libcrypto42

Description

This is a small library designed to work with the 42 projects that would need to use some cryptographic functions.

Dependencies

• make (version 4.3 or greater)
• gcc (version 13.1.1 or greater)
• The bundled libft (another library that I created in the context of 42)
• libm

And the following libraries (to build and run tests):

• Google test which is declared as a submodule of this repos (it will be pulled and built by the Makefile)
• openssl itself to use its library

How to use it

$ make # compile only libcrypto42
$ make check # run tests

To compile an executable using this library, you need to add the following libraries:

• libcrypto42.a (-L<path to libcrypto42> -lcrypto42)
• libft.a (-L<path to libft> -lft)
• The system math library (-lm)

Progress

• MD5
• SHA2 suite (sha224, sha256, sha384, sha512, sha512/224, sha512/256)
• SHA3 suite
• PBKDF
• HMAC
• DES
• AES
  • AES128
  • AES192
  • AES256
• 3DES (EDE only)
  • 2 Keys option
  • 3 Keys option
• Operation modes for symmetric encryption
  • ECB
  • CBC
  • CFB
  • OFB
  • CTR
• Base64
• Use of the Kernel CSPRNG
