I am trying to initialize the prng, but it does not seem to like the way I am initializing everything. My code is as follows #include <mycrypt.h> int main() { ...

Hi ! I'd like to use LibTomCrypt inside an AVR microcontroller (ATMega163). But I don't know how to copile LibTomCrypt for an embeded environment, and ...
... It's not likely to work as a whole. The AVR is a space limited 8-bit processor. LibTomCrypt [and most of my other libs] assume at the very least a 32-bit...
On Sunday I took the pent-up rage I had over the reviewer comments and wrote an entire new library. This one is based off of LibTomMath and provides multiple...
... Well, first I'd imagine you need to setup a cross-platform build environment, so you can compile ATMega163 binaries. Once you do that, you just need to...

I was going to release LTC 0.95 today but I decided to just get the PKCS #1 code done and over with. So far I've written an OAEP encoder [as well as the...
