The SSLeay library

The package uses libcrypto.so from SSLeay, Eric Young's implementation of the Secure Sockets Layer, to realize the commands md2 and sha1. Both are Message digests.

The official homepage can be found at http://www.ssleay.org/. A FAQ is available. An alternative is the OpenSSL project, which took the torch from Eric as he no longer works on SLLeay.

trf requires a shared library version of libcrypto. Please read the documentation of SSLeay on how to generate such a version.

A binary distribution for Windows® is currently not available, but the OpenSSL sources contain a makefile for Windows, allowing its compilation on that platform. The generated shared library crypto32.dll contains the required MD2 / SHA-1 functionality.

I have no information about its availability on MacIntosh'es.
