RSA_sign_ASN1_OCTET_STRING, RSA_verify_ASN1_OCTET_STRING -
       RSA signatures


SYNOPSIS

        #include <openssl/rsa.h>

        int RSA_sign_ASN1_OCTET_STRING(int dummy, unsigned char *m,
           unsigned int m_len, unsigned char *sigret, unsigned int *siglen,
           RSA *rsa);

        int RSA_verify_ASN1_OCTET_STRING(int dummy, unsigned char *m,
           unsigned int m_len, unsigned char *sigbuf, unsigned int siglen,
           RSA *rsa);


DESCRIPTION

       RSA_sign_ASN1_OCTET_STRING() signs the octet string m of
       size m_len using the private key rsa represented in DER
       using PKCS #1 padding. It stores the signature in sigret
       and the signature size in siglen. sigret must point to
       RSA_size(rsa) bytes of memory.

       dummy is ignored.

       The random number generator must be seeded prior to
       calling RSA_sign_ASN1_OCTET_STRING().

       RSA_verify_ASN1_OCTET_STRING() verifies that the signature
       sigbuf of size siglen is the DER representation of a given
       octet string m of size m_len. dummy is ignored. rsa is the
       signer's public key.


RETURN VALUES

       RSA_sign_ASN1_OCTET_STRING() returns 1 on success, 0
       otherwise.  RSA_verify_ASN1_OCTET_STRING() returns 1 on
       successful verification, 0 otherwise.

       The error codes can be obtained by ERR_get_error(3).


BUGS

       These functions serve no recognizable purpose.
