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.
