RSA_SIGN_ASN1_OCTET_STRING(3) FreeBSD Library Functions Manual 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. 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 or 0 otherwise. RSA_verify_ASN1_OCTET_STRING() returns 1 on successful verification or 0 otherwise. The error codes can be obtained by ERR_get_error(3). SEE ALSO RSA_new(3), RSA_sign(3), RSA_verify(3) HISTORY RSA_sign_ASN1_OCTET_STRING() and RSA_verify_ASN1_OCTET_STRING() first appeared in SSLeay 0.8.0 and have been available since OpenBSD 2.4. BUGS These functions serve no recognizable purpose. FreeBSD 14.1-RELEASE-p8 June 10, 2019 FreeBSD 14.1-RELEASE-p8
