1. Introduction

   Encrypted connections are not limited to just one way doing this.

   A list of a few encryption algorithms:
   
   (1) Advanced Encryption Standard (AES)
   (2) Data Encryption Standard (DES, 3DES)
   (3) Ron's Code 4 (RC4)
   (4) ...

   As an example a list of some kinds of the Camellia encryption
   algorithm [CAMELLIA] (names taken from OpenSSL help [OPENSSL]):

   (1) CAMELLIA-128-CBC: 128-bit Camellia encryption in CBC mode
   (2) CAMELLIA-128-ECB: 128-bit Camellia encryption in ECB mode
   (3) CAMELLIA-192-CBC: 192-bit Camellia encryption in CBC mode
   (4) CAMELLIA-192-ECB: 192-bit Camellia encryption in ECB mode
   (5) CAMELLIA-256-CBC: 256-bit Camellia encryption in CBC mode
   (6) CAMELLIA-256-ECB: 256-bit Camellia encryption in ECB mode
