 Synopsis:               FFI bindings to OpenSSL's EVP digest interface
 Description:            Foreign-function bindings to the OpenSSL library
                         <http://www.openssl.org/>. Currently provides
-                        access to the messages digests MD5, SHA, SHA1,
-                        DSS, DSS1, and RIPEMD160 through the EVP digest
-                        interface.
