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
