Encryption and Compression woes

Hey list,

I would be so grateful if I could get some help on this seemingly never-ending quest. I have not been able to solve this problem for what seems 4 months now.

I need a cross platform compression and encryption method for both a Cobalt Linux RaQ server with a MIPS processor, as well as a solution for OS X and PB

The solution would have to be C so that both the server I have created (C) and the client (mixture of C and Obj-C) could call it

I have worked with nearly every encryption algorithm (I like BlowFish the most) but I can never encrypt text on OS X, send it across a socket to the server, and decrypt it. I looked into the Big and Little endian dilemas and have tried nearly every implementation available to no luck. I would be SO grateful if someone could send some code my way. :)


Another problem of the same calibre is string compression to minimize socket use. I would like to use Zlib, but:

a) I don't know how to use Zlib in C (I know OS X has it installed) - an example would be great!
b) I don't know if the high ascii characters would be able to be decrypted serverside

Again, I would be SO grateful if someone could help me out and end my torment! :)


What about other algorithms that have worked?


Thanks in advance,

Graham Wihlidal
