+ * This is an OpenSSL-compatible implementation of the RSA Data Security,
+ * Inc. MD5 Message-Digest Algorithm (RFC 1321).
+ *
+ * Written by Solar Designer <solar at openwall.com> in 2001, and placed
+ * in the public domain.  There's absolutely no warranty.
+ *
+ * This differs from Colin Plumb's older public domain implementation in
+ * that no 32-bit integer data type is required, there's no compile-time
+ * endianness configuration, and the function prototypes match OpenSSL's.
+ * The primary goals are portability and ease of use.
+ *
+ * This implementation is meant to be fast, but not as fast as possible.
+ * Some known optimizations are not included to reduce source code size
+ * and avoid compile-time configuration.
