153 .IX Header "DESCRIPTION"
154 \&\fIRSA_sign_ASN1_OCTET_STRING()\fR signs the octet string \fBm\fR of size
155 \&\fBm_len\fR using the private key \fBrsa\fR represented in \s-1DER\s0 using \s-1PKCS\s0 #1
156 padding. It stores the signature in \fBsigret\fR and the signature size
157 in \fBsiglen\fR. \fBsigret\fR must point to \fBRSA_size(rsa)\fR bytes of
160 \&\fBdummy\fR is ignored.
162 The random number generator must be seeded prior to calling \fIRSA_sign_ASN1_OCTET_STRING()\fR.
164 \&\fIRSA_verify_ASN1_OCTET_STRING()\fR verifies that the signature \fBsigbuf\fR
165 of size \fBsiglen\fR is the \s-1DER\s0 representation of a given octet string
166 \&\fBm\fR of size \fBm_len\fR. \fBdummy\fR is ignored. \fBrsa\fR is the signer's
169 .IX Header "RETURN VALUES"
170 \&\fIRSA_sign_ASN1_OCTET_STRING()\fR returns 1 on success, 0 otherwise.
171 \&\fIRSA_verify_ASN1_OCTET_STRING()\fR returns 1 on successful verification, 0
174 The error codes can be obtained by \fIERR_get_error\fR\|(3).
