RSA_sign_ASN1_OCTET_STRING(3)					      OpenSSL					     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
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. SEE ALSO

RSA_sign_ASN1_OCTET_STRING() and RSA_verify_ASN1_OCTET_STRING() were added in SSLeay 0.8. 0.9.7d 2003-11-20 RSA_sign_ASN1_OCTET_STRING(3)

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 :-) CONFORMING TO
