OK, fair enough - point taken :)

>I would agree with Bruce Schneier also, except that it doesn't match the definition of encryption - which was my point. Not which is better (undeniable). Encoding is considered encryption simply by its definition. That is until the definition of encryption changes...

>>:) Bruce Schneier would argue that if there is no key involved then its encoding rather than encryption. A key taken from the total keyspace provides the random factor (crypto-variable) which is used in an algorithm to produce the cipher text. The same algorithm but with a different key produces a different cipher text for any given plain text. Encoding always produces the same cipher text for any given plain text because there is no key involved.
