a collaborative effort to develop a robust, commercial-grade, full-featured
Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3)
and Transport Layer Security (TLS v1) protocols as well as a full-strength
general purpose cryptography library.

The EVP_VerifyFinal() function from OpenSSL is used to determine if a
digital signature is valid.  The SSL layer in OpenSSL uses
EVP_VerifyFinal(), which in several places checks the return value
incorrectly and treats verification errors as a good signature.  This
is only a problem for DSA and ECDSA keys.");
