Overview

This is to keep backwards compatibility with the old fastlane version which used the local openssl installation. The encryption parameters in this implementation reflect the old behavior which was the most common default value in those versions. As for decryption, 1.0.x OpenSSL and earlier versions use MD5, 1.1.0c and newer uses SHA256, we try both before giving an error
