alid ECDSA signature of the hash value <i>dgst</i> of size <i>dgstlen</i> using the public key <i>eckey</i>. The parameter <i>type</i> is ignored.</p>

<p>ECDSA_do_verify() is similar to ECDSA_verify() except the signature is presented in the form of a pointer to an <b>ECDSA_SIG</b> structure.</p>

<p>The remaining functions utilise the internal <i>kinv</i> and <i>r</i> values used during signature computation. Most applications will never need to call these and some external ECDSA ENGINE implementations ma
