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.

HISTORY

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

NAME

       RSA_sign, RSA_verify - RSA signatures

SYNOPSIS

        #include <openssl/rsa.h>

        int RSA_sign(int type, const unsigned char *m, unsigned int m_len,
           unsigned char *sigret, unsigned int *siglen, RSA *rsa);

        int RSA_verify(int type, const unsigned char *m, unsigned int m_len,
           unsigned char *sigbuf, unsigned int siglen, RSA *rsa);

DESCRIPTION

       RSA_sign() signs the message digest m of size m_len using the private key rsa as specified in PKCS #1 v2.0. It stores the signature in
       sigret and the signature size in siglen. sigret must point to RSA_size(rsa) bytes of memory.

       type denotes the message digest algorithm that was used to generate m. It usually is one of NID_sha1, NID_ripemd160 and NID_md5; see
       objects(3) for details. If type is NID_md5_sha1, an SSL signature (MD5 and SHA1 message digests with PKCS #1 padding and no algorithm
       identifier) is created.

       RSA_verify() verifies that the signature sigbuf of size siglen matches a given message digest m of size m_len. type denotes the message
       digest algorithm that was used to generate the signature.  rsa is the signer's public key.

RETURN VALUES

       RSA_sign() returns 1 on success, 0 otherwise.  RSA_verify() returns 1 on successful verification, 0 otherwise.

       The error codes can be obtained by ERR_get_error(3).

BUGS

       Certain signatures with an improper algorithm identifier are accepted for compatibility with SSLeay 0.4.5 :-)
