     NAME
          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.
