:octocat: The goal of the project to recreate part of the OpenSSL functionality, specifically the MD5 and SHA-256 hashing algorithms. OpenSSL is a cryptographic toolkit library written in C that is used to secure communications over computer networks.

ft_ssl_md5

This prorgamm was a first project of security branch at 42 Silicon Valley. The goal was to recreate part of the OpenSSL functionality. OpenSSL is a cryptographic toolkit library written C that is used to secure communications over computer networks. It implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) network protocols to protect against eavesdropping and verify identities during network communication.

Implemented functions for this project: MD5, SHA254, SHA256, SHA384, SHA512.

How to use

1. Build

   make

2. Launch

   ./ft_ssl command [command opts] [command args]

Usage

• command: md5 sha224 sha256 sha384 sha512

• command opts: [-pqr] [-s string] [files ...]

  • -p, echo STDIN to STDOUT and append the checksum to STDOUT
  • -q, quiet mode
  • -r, reverse the format of the output
  • -s, print the sum of the given string

Examples

./ft_ssl md5 -s "Hello World"

MD5 ("Hello World") = b10a8db164e0754105b7a99be72e3fe5

echo "Some important message" | ./ft_ssl sha256 -p -s "Hello World" Makefile

Some important message

31d1104978e7f73a0da6375f1b0d9add90bf96fbc5ef4dc9fb16804697ef2894

SHA256("Hello World")= a591a6d40bf420404a011733cfb7b190d62c65bf0bcda32b57b277d9ad9f146e

SHA256(Makefile)= 8f959d6ccc1e4127677099b0a0f99f85cf97e232eccc1def7c13e7437c2d9b2e
