Your point about AES is a good one, and the man pages (ssh_config and
sshd_config) have now been updated.

Rijndael is not listed because it's a non-standard vendor extension that's
equivalent to aes256-cbc and is retained for config file backwards compatibility
only.  (If you put it in your config file then you ought to already know what it
is :-)

 Ciphers
       Specifies the ciphers allowed for protocol version 2 in order of
       preference.  Multiple ciphers must be comma-separated.  The sup-
       ported ciphers are ``3des-cbc'', ``aes128-cbc'', ``aes192-cbc'',
      ``aes256-cbc'', ``aes128-ctr'', ``aes192-ctr'', ``aes256-ctr'',
      ``arcfour'', ``blowfish-cbc'', and ``cast128-cbc''.  The default
       is

         ``aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,arcfour,
          aes192-cbc,aes256-cbc''
