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).
Restrictions
These functions serve no recognizable purpose.

HISTORY
RSA_sign_ASN1_OCTET_STRING() and RSA_verify_ASN1_OCTET_STRING()
were added in SSLeay 0.8.
