NAME    [Toc]    [Back]

       RSA signatures

SYNOPSIS    [Toc]    [Back]

        #include <openssl/rsa.h>

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

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

DESCRIPTION    [Toc]    [Back]

       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_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    [Toc]    [Back]

       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    [Toc]    [Back]

       These functions serve no recognizable purpose.

HISTORY    [Toc]    [Back]

       RSA_sign_ASN1_OCTET_STRING() and RSA_ver-
       ify_ASN1_OCTET_STRING() were added in SSLeay 0.8.
