/ft_ssl_md5

This C project involves implementing hash functions (MD5, SHA256, SHA512, SHA384, SHA224) and encryption algorithms (Base64, DES) from scratch, employing object-oriented programming principles.

Primary LanguageC

Examples:

HASH

  • -q, quet mode
  • -s, hash from string
> ./ft_ssl md5 file.txt
MD5 (file.txt) = ca2df19397125e25c55ce165cb209c59 # md5 hash of file

> ./ft_ssl sha384  file.txt
SHA384 (file.txt) = 7d17e90b83269decaf0564095bd733243f3caa74ff035cbb9157e3bdec49b014d93bb8bd43d36e12826f656ba6e9b099 # sha384 hash of file

> ./ft_ssl sha512 -q -s "The quick brown fox jumps over the lazy dog"

BASE64

  • -d, decode mode
  • -e, encode mode (default)
  • -i, input file
  • -o, output file
