NAME
       d2iDSAPublicKey, i2dDSAPublicKey, d2iDSAPrivateKey,
       i2dDSAPrivateKey, d2iDSAPUBKEY, i2dDSAPUBKEY, d2iDSASIG,
       i2dDSASIG - DSA key encoding and parsing functions.

SYNOPSIS
        #include 
        #include 

        DSA * d2iDSAPublicKey(DSA **a, const unsigned char **pp, long length);

        int i2dDSAPublicKey(const DSA *a, unsigned char **pp);

        DSA * d2iDSAPUBKEY(DSA **a, const unsigned char **pp, long length);

        int i2dDSAPUBKEY(const DSA *a, unsigned char **pp);

        DSA * d2iDSAPrivateKey(DSA **a, const unsigned char **pp, long length);

        int i2dDSAPrivateKey(const DSA *a, unsigned char **pp);

        DSA * d2iDSAparams(DSA **a, const unsigned char **pp, long length);

        int i2dDSAparams(const DSA *a, unsigned char **pp);

        DSA * d2iDSASIG(DSASIG **a, const unsigned char **pp, long length);

        int i2dDSASIG(const DSASIG *a, unsigned char **pp);

DESCRIPTION
       d2iDSAPublicKey() and i2dDSAPublicKey() decode and encode the DSA
       public key components structure.

       d2iDSAPUBKEY() and i2dDSAPUBKEY() decode and encode an DSA public
       key using a SubjectPublicKeyInfo (certificate public key) structure.

       d2iDSAPrivateKey(), i2dDSAPrivateKey() decode and encode the DSA
       private key components.

       d2iDSAparams(), i2dDSAparams() decode and encode the DSA parameters
       using a DDssss-PPaarrmmss structure as defined in RFC2459.

       d2iDSASIG(), i2dDSASIG() decode and encode a DSA signature using a
       DDssss-SSiigg-VVaalluuee structure as defined in RFC2459.

       The usage of all of these functions is similar to the d2iX509() and
       i2dX509() described in the d2iX509(3) manual page.

NNOOTTEESS
       The DDSSAA structure passed to the private key encoding functions should
       have all the private key components present.

       The data encoded by the private key functions is unencrypted and
       therefore offers no private key security.

       The DDSSAAPPUUBBKKEEYY functions should be used in preference to the
       DDSSAAPPuubblliiccKKeeyy functions when encoding public keys because they use a
       standard format.

       The DDSSAAPPuubblliiccKKeeyy functions use an non standard format the actual data
       encoded depends on the value of the wwrriitteeppaarraammss field of the aa key
       parameter.  If wwrriitteeppaarraammss is zero then only the ppuubbkkeeyy field is
       encoded as an IINNTTEEGGEERR. If wwrriitteeppaarraammss is 1 then a SSEEQQUUEENNCCEE consisting
       of the pp, qq, gg and ppuubbkkeeyy respectively fields are encoded.

       The DDSSAAPPrriivvaatteeKKeeyy functions also use a non standard structure consiting
       consisting of a SEQUENCE containing the pp, qq, gg and ppuubbkkeeyy and
       pprriivvkkeeyy fields respectively.
