Cryptography IP-cores & tests written in VHDL / Verilog

The components in this repository are not intended as productional code. They serve as proof of concept, for example how to implement a pipeline using only (local) variables instead of (global) signals. Furthermore they were used how to do a VHDL-to-Verilog conversion for learning purposes.

The testbenches to verify DES, AES, CTR-AES and CBC-AES are examples how useful GHDLs VHPIdirect is. They use openSSL as reference models to check the correctness of the VHDL implementation.

HINT:

The tests of some algorithms use the OSVVM library, which is redistributed as submodule. To get & initialize the submodule, please use the --recursive option when cloning this repository. Use git submodule update --recursive to update the submodule if you already chaked out the main repository.
