+
+       * yarrow256.c: Replaced uses of aes_set_key with
+       aes_set_encrypt_key. 
+
+       * nettle-meta.h (_NETTLE_CIPHER_SEP): New macro, useful for
+       algorithms with separate encyption and decryption key setup. 
+
+       * aes-internal.h (struct aes_table): New structure, including all
+       constant tables needed by the unified encryption or decryption
+       function _aes_crypt.
+
+       * aes.c (_aes_crypt): New function, which unifies encryption and
+       decryption.
+
+       AES key setup now uses two separate functions for setting
+       encryption and decryption keys. Applications that don't do
+       decryption need no inverted subkeys and no code to generate them.
+       Similarly, the tables (about 4K each for encryption and
+       decryption), are put into separate files.
+
+       * aes.h (struct aes_ctx): Deleted space for inverse subkeys. For
+       decryption, the inverse subkeys replace the normal subkeys, and
+       they are stored _in the order they are used_. 
+
+       * aes-set-key.c (aes_set_key): Deleted file, code moved...
+       * aes-set-decrypt-key.c, aes-set-encrypt-key.c: New files,
+       separated normal and inverse key setup.
+
+       * aes-tables.c: Deleted, tables moved elsewhere...
+       * aes-encrypt.c, aes-decrypt.c: New files; moved encryption and
+       decryption funktions, and needed tables, into separate files.

        * aes.c (aes_encrypt): Don't unroll the innerloop.
