AES Haskell

Note

This repository has been moved to https://github.com/henry50/aes/tree/main/aes-haskell

An implementation of the Advanced Encryption Standard in Haskell.

This implementation is not cryptographically secure.

Usage

If you don't have Stack installed, find out how to get it here.

Run the program with stack run --, followed by your options.

Usage: aes-exe (-k|--key KEY) ((-f|--file FILENAME) | (-r|--raw DATA)) 
               [-d|--decrypt] [-s]
  128, 192 and 256-bit ECB AES implementation.

Available options:
  -h,--help                Show this help text
  -k,--key KEY             Key as a hexadecimal string
  -f,--file FILENAME       Input file path
  -r,--raw DATA            Input as hexadecimal string
  -d,--decrypt             Decrypt
  -s                       Output as text

Example

To encrypt the hexadecimal 3243f6a8885a308d313198a2e0370734 with key 2b7e151628aed2a6abf7158809cf4f3c (taken from Appendix B of the standard), you would run

stack run -- -k "2b7e151628aed2a6abf7158809cf4f3c" -r "3243f6a8885a308d313198a2e0370734"

which should give 3925841d02dc09fbdc118597196a0b32. To decrypt this, run

stack run -- -k "2b7e151628aed2a6abf7158809cf4f3c" -r "3925841d02dc09fbdc118597196a0b32" -d

which should give back the original.
