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 Eric Young which was believed to be the first open-source implementation of DES. Development of SSLeay unofficially mostly ended, and volunteers forked the project under the

banner around December 1998, when Hudson and Young both commenced working for
RSA Security in Australia.
SSLeay
SSLeay was developed by Eric A. Young, starting in 1995. Windows support was added by Tim J. Hudson. Patches to open source applications to support SSL using SSLeay were produced by Tim Hudson. Development by Young and Hudson ceased in 1998. The SSLeay library and codebase is licensed under its own SSLeay License, a form of

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.
