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.
