+RFC 5581             The Camellia Cipher in OpenPGP            June 2009
+
+
+1.  Introduction
+
+   The OpenPGP protocol [RFC4880] can support many different symmetric
+   ciphers.  This document presents the necessary information to use the
+   Camellia [RFC3713] symmetric cipher in the OpenPGP protocol.
+
+2.  Requirements Notation
+
+   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
+   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
+   document are to be interpreted as described in [RFC2119].
+
+3.  Camellia
+
+   Camellia is specified in [RFC3713].  It is a 128-bit symmetric block
+   cipher (as are AES and Twofish in OpenPGP) that supports 128-bit,
+   192-bit, and 256-bit keys.  This document defines the use of Camellia
+   in OpenPGP.
+
+     +---------------------+----------------------------------------+
+     | Camellia Key Length | OpenPGP Symmetric-Key Algorithm Number |
+     +---------------------+----------------------------------------+
+     |         128         |                   11                   |
+     |         192         |                   12                   |
+     |         256         |                   13                   |
+     +---------------------+----------------------------------------+
+
+   OpenPGP applications MAY implement Camellia.  If implemented,
+   Camellia may be used in any place in OpenPGP where a symmetric cipher
+   is usable, and it is subject to the same usage requirements (such as
+   its presence in the Preferred Symmetric Algorithms signature
+   subpacket) as the other symmetric ciphers in OpenPGP.
+
+   While the OpenPGP algorithm preferences system prevents
+   interoperability problems with public key encrypted messages, if
+   Camellia (or any other optional cipher) is used for encrypting
+   private keys, there could be interoperability problems when migrating
+   a private key from one system to another.  A similar issue can arise
+   when using an optional cipher for symmetrically encrypted messages,
+   as this OpenPGP message type does not use the algorithm preferences
+   system.  Those using optional ciphers in this manner should take care
+   they are using a cipher that their intended recipient can decrypt.
+
+4.  Security Considerations
+
+   At publication time, there are no known weak keys for Camellia, and
+   the Camellia algorithm is believed to be strong.  However, as with
+   any technology involving cryptography, implementers should check the
+

+   current literature, as well as the Camellia home page at
+   http://info.isl.ntt.co.jp/camellia/ to determine if Camellia has been
+   found to be vulnerable to attack.

+
+   IANA assigned three algorithm numbers from the registry of OpenPGP
+   Symmetric-Key Algorithms that was created by [RFC4880].
