BitPunch

The goal of the project is to create a standalone implementation of the McEliece cryptosystem in C language.

Project is now only in development version.

Version 0.0.4:

• see CHANGES.txt

Documentation

• clone repo and see doc/ or visit http://fruh.github.io/BitPunch

Build:

• go to cd lib folder
• type make
  • it builds default application which is target test

Now you can build test aplication in realease or debug mode, you can specify whether you want to use precomputed H matrix (parity-check matrix - requires more memory) or not:

• make help - it is make help
• make print-info - info about where your aplication is
• make test - with H matrix
• make test-debug - with H matrix
• make test-wo-h - without H matrix
• make test-wo-debug - without H matrix
• make static - to build static lib
• make shared - to build shared lib

Built libraries are located in dist/ folder. For more preprocessor options see lib/src/bitpunch/config.h file. Default optimization is -O2. To set up more verbosity define -DERRORL, -DWARNING_L or DDEBUG_L - these are using functions like BPU_printError, BPU_printWarning, BPU_printDebug.

Example:

• examples of keygen, encryption and decryption can be found in lib/src/main.c
