=head1 SYNOPSIS
ECDSA_verify() verifies that the signature in B<sig> of size
B<siglen> is a valid ECDSA signature of the hash value
-value B<dgst> of size B<dgstlen> using the public key B<eckey>.
+B<dgst> of size B<dgstlen> using the public key B<eckey>.
The parameter B<type> is ignored.
ECDSA_do_sign() is wrapper function for ECDSA_do_sign_ex with B<kinv>
ECDSA_size() returns the maximum length signature or 0 on error.
-ECDSA_sign_setup() and ECDSA_sign() return 1 if successful or -1
+ECDSA_sign_setup() and ECDSA_sign() return 1 if successful or 0
on error.
ECDSA_verify() and ECDSA_do_verify() return 1 for a valid
int ret;
