ft_ssl [md5] [sha256]

This prorgamm was a first project of security branch at 42 Silicon Valley. The goal was to recreate part of the OpenSSL functionality.

Implemented Hash Functions

• MD5
• SHA224
• 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
