RSA_sign_ASN1_OCTET_STRING(3)
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
  The RSA_sign_ASN1_OCTET_STRING() function 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. The
  sigret must point to RSA_size(rsa) bytes of memory.

  The dummy is ignored.

  The random number generator must be seeded prior to calling the
  RSA_sign_ASN1_OCTET_STRING() function.

  The RSA_verify_ASN1_OCTET_STRING() function verifies that the signature
  sigbuf of size siglen is the DER representation of a given octet string m
  of size m_len. The dummy is ignored. The rsa is the signer's public key.

RESTRICTIONS
  These functions serve no recognizable purpose.

RETURN VALUES
  The RSA_sign_ASN1_OCTET_STRING() function returns 1 on success, 0
  otherwise. The RSA_verify_ASN1_OCTET_STRING() function returns 1 on
  successful verification, 0 otherwise.

  The error codes can be obtained by using the ERR_get_error() function.

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