110 \&\fBECDSA_size()\fR returns the maximum length of a DER encoded ECDSA signature
111 created with the private EC key \fIeckey\fR. To obtain the actual signature
114 \&\fBECDSA_sign()\fR computes a digital signature of the \fIdgstlen\fR bytes hash value
121 \&\fBECDSA_do_sign()\fR is similar to \fBECDSA_sign()\fR except the signature is returned
126 \&\fBECDSA_verify()\fR verifies that the signature in \fIsig\fR of size \fIsiglen\fR is a
127 valid ECDSA signature of the hash value \fIdgst\fR of size \fIdgstlen\fR using the
130 \&\fBECDSA_do_verify()\fR is similar to \fBECDSA_verify()\fR except the signature is
134 during signature computation. Most applications will never need to call these
143 \&\fBECDSA_sign_ex()\fR computes a digital signature of the \fIdgstlen\fR bytes hash value
145 \&\fIkinv\fR and \fIrp\fR. The DER encoded signature is stored in \fIsig\fR and its

162 signature, 0 for an invalid signature and \-1 on error.
166 Creating an ECDSA signature of a given SHA\-256 hash value using the
185 Second step: compute the ECDSA signature of a SHA\-256 hash value
207 Third step: verify the created ECDSA signature using \fBECDSA_do_verify()\fR:
