RSA_sign_ASN1_OCTET_STRING(3openssl) OpenSSL RSA_sign_ASN1_OCTET_STRING(3openssl)NAMERSA_sign_ASN1_OCTET_STRING, RSA_verify_ASN1_OCTET_STRING - RSA signaturesSYNOPSIS#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);DESCRIPTIONRSA_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 VALUESRSA_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).BUGSThese functions serve no recognizable purpose.SEE ALSOERR_get_error(3), objects(3), rand(3), rsa(3), RSA_sign(3), RSA_verify(3)HISTORYRSA_sign_ASN1_OCTET_STRING() and RSA_verify_ASN1_OCTET_STRING() were added in SSLeay 0.8.
