[SOLVED] blowfish algorithm: encrypting the p-array.
Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!
1. The problem statement, all variables and given/known data:
I am trying to encrypt the p-array. The first element will print correctly once returned from my encrypt function, but that is after it is shifted back and forth. When printed from its initial creation it is the number I need with an extra 2 on the far left. I was also able to get the Ri to print, but I don't remember why. None of the other numbers seemed correct for the p-array. Possibly something about endianness? I'll be looking up what that is.
2. Relevant commands, code, scripts, algorithms:
Here is the given key we take from the command line. Also, here is the p-array we are trying to produce after the encryption.
Code:
KEY: 9abcdef012345678
P ARRAY
8e620a62 820f473e f6cdeb7b 5a03458a ed4cb11d 6b8d2187

3. The attempts at a solution (include all code and scripts):
Code:
/*
=============================================================
The hex digits of pi, arranged as four s_boxes & one p_array,
as per the Blowfish default. These have passed muster w/ Eric
Young's set of test vectors. Enjoy. -Mike Schaudies
