The project is 15291719Sjkim managed by a worldwide community of volunteers that use the Internet to 16291719Sjkim communicate, plan, and develop the OpenSSL toolkit and its related 17291719Sjkim documentation. 1855714Skris 19291719Sjkim OpenSSL is descended from the SSLeay library developed by Eric A. Young 2055714Skris and Tim J. Hudson.
