+ * Eric Young implemented DES in the library libdes, that grew into
+ * libcrypto in the ssleay package. ssleay went into recession and
+ * then got picked up by the OpenSSL (htp://www.openssl.org/)
+ * project.
+ *
+ * libhcrypto is an independent implementation with no code decended
+ * from ssleay/openssl. Both includes some common imported code, for
+ * example the AES implementation.
