Partial reimplementation of OpenSSL

This is an outer circle projects at 42. Its goal is to understand and implement some features of OpenSSL.

It is split across 3 sub-projects, each focusing on an aspect of OpenSSL:

• ft_ssl_md5 -> hashing
  • md5
  • sha224 (optional)
  • sha256
  • sha384 (optional)
  • sha512 (optional)
• ft_ssl_des -> cipher/encryption
  • des
  • des-ecb
  • des-cbc
  • des-ofb (optional)
  • des3 (optional)
  • base64
• ft_ssl_rsa -> public key encryption/decryption
  • genrsa
  • rsa
  • rsautl
  • gendsa (optional)
  • gendes (optional)

• ft_ssl_md5 ongoing

  • Mandatory:
    • md5
    • sha256
  • Bonus:
    • sha224
    • sha384
    • sha512
  • Other:
    • sha1
    • sha3-256 (and variants)
    • rmd160 (and variants)
    • gost
    • sm3
    • shake128 (and shake256)
    • tiger

• ft_ssl_des maybe later

• ft_ssl_rsa maybe later
