DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN These functions load the certificates and private keys intothe SSL_CTX or SSL object, respectively.
The SSL_CTX_* class of functions loads the certificates and
keys into the SSL_CTX object ccccttttxxxx. The information is passed
to SSL objects ssssssssllll created from ccccttttxxxx with SSL_new(3) by
copying, so that changes applied to ccccttttxxxx do not propagate to already existing SSL objects.8/Apr/2005 Last change: 0.9.8o 1
OpenSSL SSL_CTX_use_certificate(3openssl)
The SSL_* class of functions only loads certificates and
keys into a specific SSL object. The specific information iskept, when SSL_clear(3) is called for this SSL object.
SSL_CTX_use_certificate() loads the certificate xxxx into ccccttttxxxx,
SSL_use_certificate() loads xxxx into ssssssssllll. The rest of the
certificates needed to form the complete certificate chaincan be specified using the SSL_CTX_add_extra_chain_cert(3)
function.SSL_CTX_use_certificate_ASN1() loads the ASN1 encoded
certificate from the memory location dddd (with length lllleeeennnn)into ccccttttxxxx, SSL_use_certificate_ASN1() loads the ASN1 encoded
certificate into ssssssssllll.SSL_CTX_use_certificate_file() loads the first certificate
stored in ffffiiiilllleeee into ccccttttxxxx. The formatting ttttyyyyppppeeee of the certificate must be specified from the known typesSSL_FILETYPE_PEM, SSL_FILETYPE_ASN1.
SSL_use_certificate_file() loads the certificate from ffffiiiilllleeee
into ssssssssllll. See the NOTES section on whySSL_CTX_use_certificate_chain_file() should be preferred.
SSL_CTX_use_certificate_chain_file() loads a certificate
chain from ffffiiiilllleeee into ccccttttxxxx. The certificates must be in PEM format and must be sorted starting with the subject's certificate (actual client or server certificate), followed by intermediate CA certificates if applicable, and ending at the highest level (root) CA. There is no corresponding function working on a single SSL object.SSL_CTX_use_PrivateKey() adds ppppkkkkeeeeyyyy as private key to ccccttttxxxx.
SSL_CTX_use_RSAPrivateKey() adds the private key rrrrssssaaaa of type
RSA to ccccttttxxxx. SSL_use_PrivateKey() adds ppppkkkkeeeeyyyy as private key to
ssssssssllll; SSL_use_RSAPrivateKey() adds rrrrssssaaaa as private key of type
RSA to ssssssssllll. If a certificate has already been set and the private does not belong to the certificate an error is returned. To change a certificate, private key pair the newcertificate needs to be set with SSL_use_certificate() or
SSL_CTX_use_certificate() before setting the private key
with SSL_CTX_use_PrivateKey() or SSL_use_PrivateKey().
SSL_CTX_use_PrivateKey_ASN1() adds the private key of type
ppppkkkk stored at memory location dddd (length lllleeeennnn) to ccccttttxxxx.SSL_CTX_use_RSAPrivateKey_ASN1() adds the private key of
type RSA stored at memory location dddd (length lllleeeennnn) to ccccttttxxxx.SSL_use_PrivateKey_ASN1() and SSL_use_RSAPrivateKey_ASN1()
add the private key to ssssssssllll.SSL_CTX_use_PrivateKey_file() adds the first private key
found in ffffiiiilllleeee to ccccttttxxxx. The formatting ttttyyyyppppeeee of the certificatemust be specified from the known types SSL_FILETYPE_PEM,

SSL_FILETYPE_ASN1. SSL_CTX_use_RSAPrivateKey_file() adds
the first private RSA key found in ffffiiiilllleeee to ccccttttxxxx.SSL_use_PrivateKey_file() adds the first private key found
in ffffiiiilllleeee to ssssssssllll; SSL_use_RSAPrivateKey_file() adds the first
private RSA key found to ssssssssllll.SSL_CTX_check_private_key() checks the consistency of a
private key with the corresponding certificate loaded intoccccttttxxxx. If more than one key/certificate pair (RSA/DSA) is installed, the last item installed will be checked. If e.g. the last item was a RSA certificate or key, the RSA key/certificate pair will be checked.
SSL_check_private_key() performs the same check for ssssssssllll. If
no key/certificate was explicitly added for this ssssssssllll, the last item added into ccccttttxxxx will be checked.

When reading certificates and private keys from file, filesof type SSL_FILETYPE_ASN1 (also known as DDDDEEEERRRR, binary
encoding) can only contain one certificate or private key,consequently SSL_CTX_use_certificate_chain_file() is only
applicable to PEM formatting. Files of typeSSL_FILETYPE_PEM can contain more than one item.
SSL_CTX_use_certificate_chain_file() adds the first
certificate found in the file to the certificate store. The other certificates are added to the store of chaincertificates using SSL_CTX_add_extra_chain_cert(3). There
exists only one extra chain store, so that the same chain is appended to both types of certificates, RSA and DSA! If it is not intended to use both type of certificate at the same time, it is recommended to use theSSL_CTX_use_certificate_chain_file() instead of the
SSL_CTX_use_certificate_file() function in order to allow
the use of complete certificate chains even when no trusted CA storage is used or when the CA issuing the certificate shall not be added to the trusted CA storage. If additional certificates are needed to complete the chain during the TLS negotiation, CA certificates are additionally looked up in the locations of trusted CA certificates, seeSSL_CTX_load_verify_locations(3).
The private keys loaded from file can be encrypted. In order to successfully load encrypted keys, a function returning the passphrase must have been supplied, seeSSL_CTX_set_default_passwd_cb(3). (Certificate files might
be encrypted as well from the technical point of view, it8/Apr/2005 Last change: 0.9.8o 3
