Hi Don,

Thanks for your reply, very much appreciated. Totally agree with what you suggested RE: delivering password security.

Just to clarify though, does that mean it is not possible to do the reverse of
Code:
echo '[q]sa[ln0=aln256%Pln256/snlbx]sb3135071790101768542287578439snlbxq'|dc

? Smilie

I am a bit curious of a way to a generate a 'magic'/garbled string of some sort. For example, how do I work out what string echo | dc would give me 'Hello World'? It does not have to be echo | dc, perhaps there is another UNIX command that is easier to use that can achieve the same thing.

I know it is trivial. I guess that is why I say UNIX fun Smilie I want to create a simple tagline of some sort to use for my scripts so I can more easily identify which ones I've written and not tampered with.
