+// SSHKDF is a key derivation function used in the SSH Transport Layer Protocol
+// defined in Section 7.2 of RFC 4253. It calculates a derived key |out| of
+// length |out_len| bytes using |evp_md| hash algorithm from the supplied
+// shared secret |key|, hash value |xcghash| and session identifier
+// |session_id|. It returns one on success and zero on error.
+//
+// |xcghash| is produced during the SSH Diffie-Hellman exchange.
