SSLeay

SSLeay is an open-source SSL implementation. It was developed by Eric Andrew Young and Tim J. Hudson as an SSL 3.0 implementation using RC2 and RC4 encryption. The recommended pronunciation is to say each letter s-s-l-e-a-y and was first developed by Eric A. Young ("eay"). SSLeay also included an implementation of the DES from earlier work by Tim Hudson which was believed to be the first open-source implementation of DES. Development of SSLeay unofficially mostly ended, and the volunteers maintaining the codebase forked the project under the OpenSSL banner around December 1998, when Tim and Eric both moved to work for RSA Security.

SSLeay was developed by Eric A. Young, starting in 1995. Windows support was added by Tim J. Hudson. Development by Young and Hudson ceased in 1998. The SSLeay library and codebase is licensed under its own SSLeay License, a form of free software license. The SSLeay License is a BSD-style open-source license.

SSLeay supports X.509v3 certificates and PKCS#10 certificate requests. It supports SSL2 and SSL3. Also supported is TLSv1.

The first secure FTP implementation was created under BSD using SSLeay by Tim Hudson.

The first open source Certifying Authority implementation was created with CGI scripts using SSLeay by Clifford Heath.

OpenSSL is a fork and successor project to SSLeay and has a similar interface to it. After Young and Hudson joined RSA Corporation, volunteers forked SSLeay and continued development as OpenSSL.

RSA SSL-C is a fork of SSLeay developed by Eric A. Young and Tim J. Hudson for RSA Corporation. It was released as part of RSA BSAFE.
