Need a DES Encryption specialist

I'm looking for an encryption expert to help analyze a data file.

The knowledge of linux is a plus

The knowledge of c/asm is a plus

The knowledge of powerpc is a plus

The knowledge of other encryption, like 3DES, TEA, RSA, is a plus

Please include this text in your bid.


The plantext, the ciphertext, and the key go like this.

plantext: 37 31 31 36 38 36 30 32 44 47 34 32 30 30 35 32 30 33 37 35

ciphertext or key? I'm not sure: A2 BB 09 CC 5D 44 F6 33

ciphertext or key? I'm not sure: 1C E9 E6 51 33 82 C7 37 6F A2 FB 70 3D C9 F6 D5 93 57 F9 2E DD F9 C2 CC

You see I know they are plantext, ciphertext and key. But I don't know how the ciphertext is calculated out of the plantext, and how to play with KS, Salt, and etc.

Please PM me if you got any clue or need more information.

I've extended the project, and increased the budget. So feel free to bid higher than $250, if you think you can make it.
