The Shell Cipher (Challenge)

[Tiberius]

As I said before, if you want me to encrypt something (a phrase, a letter, a word, etc) under the same key I used in this one, or a custom key, let me know. I wrote a program to do it all so it will literally take seconds.

Here's hoping it's leaky like crazy.

Post a bunch more samples, unrelated if necessary to Shell's unique letters. Thank you.

[Tiberius]

Do you want samples with a known plaintext, or do you just want me to find some random paragraphs and encrypt them without saying what they mean?

[Tiberius]

Bump just in case Synackaon didn't see this.

[Autumnlicious]

Well, if you post plain -> encrypted, then it becomes a matter of figuring out what transforms you did to it to go from plain->encrypted. If its sufficiently complex of a cipher, that will be needed to solve quickly.

If it's simpler than that, blocks of encrypted text.

If Shell is impatient:
plain-> encrypted samples.

If not, just couple of encrypted samples.

I've been meaning to pick up on cryptography and poke at it just to see what it is.

This would be the first cipher I've ever attempted to solve... not having much luck I have to admit.

Ok, a couple more (same key as the first):

and a much longer one:
