NAME

gpgsm - CMS encryption and signing tool

SYNOPSIS

gpgsm [--homedir dir] [--options file] [options] command

[args]

DESCRIPTION

gpgsm is a tool similar to gpg to provide digital encryption

and signing services on X.509 certificates and the CMS pro-

tocol. It is mainly used as a backend for S/MIME mail pro-

cessing. gpgsm includes a full features certificate manage-

ment and complies with all rules defined for the German Sphinx project. COMMANDS Commands are not distinguished from options except for the fact that only one command is allowed. Commands not specific to the function

--version

Print the program version and licensing information. Note that you cannot abbreviate this command.

--help, -h

Print a usage message summarizing the most useful

command-line options. Note that you cannot abbreviate

this command.

--warranty

Print warranty information. Note that you cannot abbreviate this command.

--dump-options

Print a list of all available options and commands. Note that you cannot abbreviate this command.

GNU Privacy Guard GPGSM(1) Commands to select the type of

--encrypt

Perform an encryption. The keys the data is encrypted

too must be set using the option --recipient.

--decrypt

Perform a decryption; the type of input is automati-

cally determined. It may either be in binary form or

PEM encoded; automatic determination of base-64 encod-

ing is not done.

--sign

Create a digital signature. The key used is either the

fist one found in the keybox or those set with the --

local-user option.

--verify

Check a signature file for validity. Depending on the arguments a detached signature may also be checked.

--server

Run in server mode and wait for commands on the stdin.

--call-dirmngr command [args]

Behave as a Dirmngr client issuing the request command with the optional list of args. The output of the Dirmngr is printed stdout. Please note that file names given as arguments should have an absolute file name

(i.e. commencing with / because they are passed verba-

tim to the Dirmngr and the working directory of the Dirmngr might not be the same as the one of this client. Currently it is not possible to pass data via stdin to the Dirmngr. command should not contain spaces. This is command is required for certain maintaining tasks of the dirmngr where a dirmngr must be able to

call back to gpgsm. See the Dirmngr manual for

details.

--call-protect-tool arguments

Certain maintenance operations are done by an external

program call gpg-protect-tool; this is usually not

GNU Privacy Guard GPGSM(1) installed in a directory listed in the PATH variable. This command provides a simple wrapper to access this tool. arguments are passed verbatim to this command;

use --help to get a list of supported operations.

How to manage the certificates and

--gen-key

This command allows the creation of a certificate sign-

ing request. It is commonly used along with the --

output option to save the created CSR into a file. If

used with the --batch a parameter file is used to

create the CSR.

--list-keys

-k List all available certificates stored in the local key

database. Note that the displayed data might be refor-

matted for better human readability and illegal charac-

ters are replaced by safe substitutes.

--list-secret-keys

-K List all available certificates for which a correspond-

ing a secret key is available.

--list-external-keys pattern

List certificates matching pattern using an external server. This utilizes the dirmngr service.

--list-chain

Same as --list-keys but also prints all keys making up

the chain.

--dump-cert

--dump-keys

List all available certificates stored in the local key database using a format useful mainly for debugging.

GNU Privacy Guard GPGSM(1)

--dump-chain

Same as --dump-keys but also prints all keys making up

the chain.

--dump-secret-keys

List all available certificates for which a correspond-

ing a secret key is available using a format useful mainly for debugging.

--dump-external-keys pattern

List certificates matching pattern using an external server. This utilizes the dirmngr service. It uses a format useful mainly for debugging.

--keydb-clear-some-cert-flags

This is a debugging aid to reset certain flags in the

key database which are used to cache certain certifi-

cate stati. It is especially useful if a bad CRL or a weird running OCSP responder did accidentally revoke

certificate. There is no security issue with this com-

mand because gpgsm always make sure that the validity

of a certificate is checked right before it is used.

--delete-keys pattern

Delete the keys matching pattern. Note that there is no command to delete the secret part of the key directly. In case you need to do this, you should run

the command gpgsm --dump-secret-keys KEYID before you

delete the key, copy the string of hex-digits in the

``keygrip'' line and delete the file consisting of

these hex-digits and the suffix .key from the private-

keys-v1.d directory below our GnuPG home directory

(usually ~/.gnupg).

--export [pattern]

Export all certificates stored in the Keybox or those

specified by the optional pattern. Those pattern con-

sist of a list of user ids (see: [how-to-specify-a-

user-id]). When used along with the --armor option a

few informational lines are prepended before each

block. There is one limitation: As there is no com-

monly agreed upon way to pack more than one certificate into an ASN.1 structure, the binary export (i.e. without using armor) works only for the export of one certificate. Thus it is required to specify a pattern

which yields exactly one certificate. Ephemeral certi-

ficate are only exported if all pattern are given as

GnuPG 2.0.13 Last change: 2010-10-12 4

GNU Privacy Guard GPGSM(1) fingerprints or keygrips.

--export-secret-key-p12 key-id

Export the private key and the certificate identified

by key-id in a PKCS#12 format. When using along with

the --armor option a few informational lines are

prepended to the output. Note, that the PKCS#12 format

is not very secure and this command is only provided if there is no other way to exchange the private key.

(see: [option --p12-charset])

--import [files]

Import the certificates from the PEM or binary encoded

files as well as from signed-only messages. This com-

mand may also be used to import a secret key from a

PKCS#12 file.

--learn-card

Read information about the private keys from the smartcard and import the certificates from there. This

command utilizes the gpg-agent and in turn the scdae-

mon.

--passwd user_id

Change the passphrase of the private key belonging to

the certificate specified as user_id. Note, that

changing the passphrase/PIN of a smartcard is not yet supported. OPTIONS GPGSM comes features a bunch of options to control the exact behaviour and to change the default configuration. How to change the configuration These options are used to change the configuration and are usually found in the option file.

GnuPG 2.0.13 Last change: 2010-10-12 5

GNU Privacy Guard GPGSM(1)

--options file

Reads configuration from file instead of from the

default per-user configuration file. The default con-

figuration file is named gpgsm.conf and expected in the

.gnupg directory directly below the home directory of the user.

--homedir dir

Set the name of the home directory to dir. If this option is not used, the home directory defaults to

~/.gnupg. It is only recognized when given on the com-

mand line. It also overrides any home directory stated through the environment variable GNUPGHOME or (on W32 systems) by means of the Registry entry HKCU\Software\GNU\GnuPG:HomeDir.

-v

--verbose

Outputs additional information while running. You can

increase the verbosity by giving several verbose com-

mands to gpgsm, such as -vv.

--policy-file filename

Change the default name of the policy file to filename.

--agent-program file

Specify an agent program to be used for secret key operations. The default value is the

/usr/local/bin/gpg-agent. This is only used as a fall-

back when the environment variable GPG_AGENT_INFO is

not set or a running agent can't be connected.

--dirmngr-program file

Specify a dirmngr program to be used for CRL checks. The default value is /usr/sbin/dirmngr. This is only used as a fallback when the environment variable

DIRMNGR_INFO is not set or a running dirmngr can't be

connected.

--prefer-system-dirmngr

If a system wide dirmngr is running in daemon mode, first try to connect to this one. Fallback to a pipe based server if this does not work. Under Windows this

GnuPG 2.0.13 Last change: 2010-10-12 6

GNU Privacy Guard GPGSM(1) option is ignored because the system dirmngr is always used.

--disable-dirmngr

Entirely disable the use of the Dirmngr.

--no-secmem-warning

Don't print a warning when the so called "secure memory" can't be used.

--log-file file

When running in server mode, append all logging output to file. Certificate related options

--enable-policy-checks

--disable-policy-checks

By default policy checks are enabled. These options may be used to change it.

--enable-crl-checks

--disable-crl-checks

By default the CRL checks are enabled and the DirMngr is used to check for revoked certificates. The disable

option is most useful with an off-line network connec-

tion to suppress this check.

--enable-trusted-cert-crl-check

--disable-trusted-cert-crl-check

By default the CRL for trusted root certificates are checked like for any other certificates. This allows a CA to revoke its own certificates voluntary without the need of putting all ever issued certificates into a CRL. The disable option may be used to switch this extra check off. Due to the caching done by the Dirmngr, there won't be any noticeable performance

GnuPG 2.0.13 Last change: 2010-10-12 7

GNU Privacy Guard GPGSM(1) gain. Note, that this also disables possible OCSP checks for trusted root certificates. A more specific way of disabling this check is by adding the ``relax'' keyword to the root CA line of the trustlist.txt

--force-crl-refresh

Tell the dirmngr to reload the CRL for each request. For better performance, the dirmngr will actually optimize this by suppressing the loading for short time intervals (e.g. 30 minutes). This option is useful to

make sure that a fresh CRL is available for certifi-

cates hold in the keybox. The suggested way of doing

this is by using it along with the option --with-

validation for a key listing command. This option should not be used in a configuration file.

--enable-ocsp

--disable-ocsp

Be default OCSP checks are disabled. The enable option may be used to enable OCSP checks via Dirmngr. If CRL

checks are also enabled, CRLs will be used as a fall-

back if for some reason an OCSP request won't succeed. Note, that you have to allow OCSP requests in Dirmngr's

configuration too (option --allow-ocsp and configure

dirmngr properly. If you don't do so you will get the error code Not supported.

--auto-issuer-key-retrieve

If a required certificate is missing while validating the chain of certificates, try to load that certificate from an external location. This usually means that Dirmngr is employed to search for the certificate. Note that this option makes a "web bug" like behavior possible. LDAP server operators can see which keys you request, so by sending you a message signed by a brand new key (which you naturally will not have on your local keybox), the operator can tell both your IP address and the time when you verified the signature.

--validation-model name

This option changes the default validation model. The only possible values are "shell" (which is the default) and "chain" which forces the use of the chain model. The chain model is also used if an option in the trustlist.txt or an attribute of the certificate

GnuPG 2.0.13 Last change: 2010-10-12 8

GNU Privacy Guard GPGSM(1) requests it. However the standard model (shell) is in that case always tried first. Input and Output

--armor

-a Create PEM encoded output. Default is binary output.

--base64

Create Base-64 encoded output; i.e. PEM without the

header lines.

--assume-armor

Assume the input data is PEM encoded. Default is to autodetect the encoding but this is may fail.

--assume-base64

Assume the input data is plain base-64 encoded.

--assume-binary

Assume the input data is binary encoded.

--p12-charset name

gpgsm uses the UTF-8 encoding when encoding passphrases

for PKCS#12 files. This option may be used to force

the passphrase to be encoded in the specified encoding name. This is useful if the application used to import the key uses a different encoding and thus won't be

able to import a file generated by gpgsm. Commonly

used values for name are Latin1 and CP850. Note that

gpgsm itself automagically imports any file with a

passphrase encoded to the most commonly used encodings.

--default-key user_id

Use user_id as the standard key for signing. This key

is used if no other key has been defined as a signing

GnuPG 2.0.13 Last change: 2010-10-12 9

GNU Privacy Guard GPGSM(1)

key. Note, that the first --local-users option also

sets this key if it has not yet been set; however --

default-key always overrides this.

--local-user user_id

-u user_id

Set the user(s) to be used for signing. The default is the first secret key found in the database.

--recipient name

-r Encrypt to the user id name. There are several ways a

user id may be given (see: [how-to-specify-a-user-id]).

--output file

-o file

Write output to file. The default is to write it to stdout.

--with-key-data

Displays extra information with the --list-keys com-

mands. Especially a line tagged grp is printed which tells you the keygrip of a key. This string is for example used as the file name of the secret key.

--with-validation

When doing a key listing, do a full validation check for each key and print the result. This is usually a slow operation because it requires a CRL lookup and other operations.

When used along with --import, a validation of the cer-

tificate to import is done and only imported if it succeeds the test. Note that this does not affect an already available certificate in the DB. This option is therefore useful to simply verify a certificate.

--with-md5-fingerprint

For standard key listings, also print the MD5

GnuPG 2.0.13 Last change: 2010-10-12 10

GNU Privacy Guard GPGSM(1) fingerprint of the certificate. How to change how the CMS

--include-certs n

Using n of -2 includes all certificate except for the

root cert, -1 includes all certs, 0 does not include

any certs, 1 includes only the signers cert (this is the default) and all other positive values include up to n certificates starting with the signer cert.

--cipher-algo oid

Use the cipher algorithm with the ASN.1 object identif-

ier oid for encryption. For convenience the strings 3DES, AES and AES256 may be used instead of their OIDs. The default is 3DES (1.2.840.113549.3.7).

--digest-algo name

Use name as the message digest algorithm. Usually this

algorithm is deduced from the respective signing certi-

ficate. This option forces the use of the given algo-

rithm and may lead to severe interoperability problems. Doing things one usually don't want

--extra-digest-algo name

Sometimes signatures are broken in that they announce a

different digest algorithm than actually used. gpgsm

uses a one-pass data processing model and thus needs to

rely on the announced digest algorithms to properly hash the data. As a workaround this option may be used to tell gpg to also hash the data using the algorithm name; this slows processing down a little bit but

allows to verify such broken signatures. If gpgsm

prints an error like ``digest algo 8 has not been

GnuPG 2.0.13 Last change: 2010-10-12 11

GNU Privacy Guard GPGSM(1) enabled'' you may want to try this option, with SHA256 for name.

--faked-system-time epoch

This option is only useful for testing; it sets the system time back or forth to epoch which is the number of seconds elapsed since the year 1970. Alternatively epoch may be given as a full ISO time string (e.g. "20070924T154812").

--with-ephemeral-keys

Include ephemeral flagged keys in the output of key listings. Note that they are included anyway if the key specification for a listing is given as fingerprint or keygrip.

--debug-level level

Select the debug level for investigating problems. level may be one of: none no debugging at all. basic some basic debug messages advanced more verbose debug messages expert even more detailed messages guru all of the debug messages you can get How these messages are mapped to the actual debugging flags is not specified and may change with newer releases of this program. They are however carefully selected to best aid in debugging.

--debug flags

This option is only useful for debugging and the behaviour may change at any time without notice; using

--debug-levels is the preferred method to select the

debug verbosity. FLAGS are bit encoded and may be

given in usual C-Syntax. The currently defined bits

are:

GnuPG 2.0.13 Last change: 2010-10-12 12

GNU Privacy Guard GPGSM(1) 0 (1) X.509 or OpenPGP protocol related data 1 (2) values of big number integers 2 (4) low level crypto operations 5 (32) memory allocation 6 (64) caching 7 (128) show memory statistics. 9 (512)

write hashed data to files named dbgmd-000*

10 (1024) trace Assuan protocol

Note, that all flags set using this option may get overrid-

den by --debug-level.

--debug-all

Same as --debug=0xffffffff

--debug-allow-core-dump

Usually gpgsm tries to avoid dumping core by well writ-

ten code and by disabling core dumps for security rea-

sons. However, bugs are pretty durable beasts and to squash them it is sometimes useful to have a core dump. This option enables core dumps unless the Bad Thing happened before the option parsing.

--debug-no-chain-validation

This is actually not a debugging option but only useful

as such. It lets gpgsm bypass all certificate chain

validation checks.

--debug-ignore-expiration

This is actually not a debugging option but only useful

as such. It lets gpgsm ignore all notAfter dates, this

is used by the regression tests.

--fixed-passphrase string

Supply the passphrase string to the gpg-protect-tool.

This option is only useful for the regression tests included with this package and may be revised or removed at any time without notice.

--no-common-certs-import

Suppress the import of common certificates on keybox creation.

All the long options may also be given in the confi-

guration file after stripping off the two leading dashes. HOW TO SPECIFY A USER ID There are different ways to specify a user ID to GnuPG. Some of them are only valid for gpg others are only good for

gpgsm. Here is the entire list of ways to specify a key:

By key Id. This format is deduced from the length of the string and its content or 0x prefix. The key Id of an X.509

certificate are the low 64 bits of its SHA-1 finger-

print. The use of key Ids is just a shortcut, for all automated processing the fingerprint should be used. When using gpg an exclamation mark (!) may be appended to force using the specified primary or secondary key and not to try and calculate which primary or secondary key to use. The last four lines of the example give the key ID in

their long form as internally used by the OpenPGP pro-

tocol. You can see the long key ID using the option --

with-colons.

GnuPG 2.0.13 Last change: 2010-10-12 14

GNU Privacy Guard GPGSM(1) By fingerprint. This format is deduced from the length of the string and its content or the 0x prefix. Note, that only the

20 byte version fingerprint is available with gpgsm

(i.e. the SHA-1 hash of the certificate).

When using gpg an exclamation mark (!) may be appended to force using the specified primary or secondary key and not to try and calculate which primary or secondary key to use. The best way to specify a key Id is by using the fingerprint. This avoids any ambiguities in case that there are duplicated key IDs. 1234343434343434C434343434343434 123434343434343C3434343434343734349A3434 0E12343434343434343434EAB3484343434343434 0xE12343434343434343434EAB3484343434343434

(gpgsm also accepts colons between each pair of hexadecimal

digits because this is the de-facto standard on how to

present X.509 fingerprints.) By exact match on OpenPGP user This is denoted by a leading equal sign. It does not make sense for X.509 certificates.

=Heinrich Heine

By exact match on an email This is indicated by enclosing the email address in the usual way with left and right angles.

By word match. All words must match exactly (not case sensitive) but can appear in any order in the user ID or a subjects name. Words are any sequences of letters, digits, the underscore and all characters with bit 7 set. +Heinrich Heine duesseldorf By exact match on the subject's This is indicated by a leading slash, directly followed

by the RFC-2253 encoded DN of the subject. Note that

you can't use the string printed by "gpgsm --list-keys"

because that one as been reordered and modified for

better readability; use --with-colons to print the raw

(but standard escaped) RFC-2253 string

/CN=Heinrich Heine,O=Poets,L=Paris,C=FR By exact match on the issuer's

This is indicated by a leading hash mark, directly fol-

lowed by a slash and then directly followed by the rfc2253 encoded DN of the issuer. This should return the Root cert of the issuer. See note above.

#/CN=Root Cert,O=Poets,L=Paris,C=FR

By exact match on serial number

This is indicated by a hash mark, followed by the hexa-

decimal representation of the serial number, then fol-

lowed by a slash and the RFC-2253 encoded DN of the

issuer. See note above.

#4F03/CN=Root Cert,O=Poets,L=Paris,C=FR

By keygrip This is indicated by an ampersand followed by the 40

hex digits of a keygrip. gpgsm prints the keygrip when

using the command --dump-cert. It does not yet work

for OpenPGP keys. &D75F22C3F86E355877348498CDC92BD21010A480 By substring match. This is the default mode but applications may want to explicitly indicate this by putting the asterisk in front. Match is not case sensitive. Heine *Heine Please note that we have reused the hash mark identifier which was used in old GnuPG versions to indicate the so

called local-id. It is not anymore used and there should be

no conflict when used with X.509 stuff.

GNU Privacy Guard GPGSM(1)

Using the RFC-2253 format of DNs has the drawback that it is

not possible to map them back to the original encoding, how-

ever we don't have to do this because our key database stores this encoding as meta data.

An adminis- </P> trator may replace this file with a custom one. The <P><P> format is a concatenation of PEM encoded X.509 certifi- </P> cates. This global file is installed in the data directory (e.g. /usr/share/gnupg/qualified.txt). Note that on larger installations, it is useful to put predefined files into the directory /etc/skel/.gnupg/ so <P><P> that newly created users start up with a working configura- </P> tion. For existing users a small helper script is provided to create these files (see: [addgnupghome]). <P><H3> For internal purposes gpgsm creates and maintains a few </H3> other files; they all live in in the current home directory <P><H3> (see: [option --homedir]). Only gpgsm may modify these </H3> files. pubring.kbx This a database file storing the certificates as well as meta information. For debugging purposes the tool kbxutil may be used to show the internal structure of this file. You should backup this file. <P><P> random_seed </P> This content of this file is used to maintain the internal state of the random number generator across invocations. The same file is used by other programs of this software too. <P><P> S.gpg-agent </P> If this file exists and the environment variable <P><H3> GPG_AGENT_INFO is not set, gpgsm will first try to connect </H3><P><P> to this socket for accessing gpg-agent before starting a new </P><P><P> gpg-agent instance. Under Windows this socket (which in </P> <P><P>GnuPG 2.0.13 Last change: 2010-10-12 20 </P> GNU Privacy Guard GPGSM(1) reality be a plain file describing a regular TCP listening <P><P> port) is the standard way of connecting the gpg-agent. </P> <P><H3>SEE ALSO </H3><P><P> gpg2(1), gpg-agent(1) </P> <P><P> The full documentation for this tool is maintained as a Tex- </P> info manual. If GnuPG and the info program are properly installed at your site, the command info gnupg should give you access to the complete manual including a menu structure and an index. <P><H3>ATTRIBUTES </H3><P><P> See attributes(5) for descriptions of the following attri- </P> butes: <P><P> _______________________________________ </P><P><H3> | ATTRIBUTE TYPE | ATTRIBUTE VALUE| </H3><P><P> |____________________|__________________|_ </P> | Availability | crypto/gnupg | <P><P> |____________________|__________________|_ </P> | Interface Stability| Uncommitted | <P><P> |____________________|_________________| </P> NOTES Source for GnuPG is available at http://opensolaris.org and at http://www.gnupg.org.
