+/* Snefru is a cryptographic hash function invented by Ralph Merkle
+ * which supports 128-bit and 256-bit output. It was named after the
+ * Egyptian Pharaoh Sneferu, continuing the tradition of the Khufu and
+ * Khafre block ciphers.
+ *
+ * Snefru is a public-domain one-way hash function. For more information see
+ * http://www.funet.fi/pub/crypt/mirrors/idea.sec.dsi.unimi.it/rpub.cl.msu.edu/
+ *   crypt/docs/merkle-khufu-khafre-snefru.txt.gz
+ *
+ * This code was written by B. Poettering in 2004 for the mhash library. It
+ * is in the public domain.
