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.
