About The Project

A miniature implementation of openssl implementing several encryption and hashing algorithms, namely:

• md5
• sha-256
• base64
• des-ecb
• des-cbC
• des-pcbc
• des3-ecb
• des3-cbc
• des3-pcbc
• scrypt

Built With

ft_ssl is developed in C using gcc, with no outside dependencies.

Getting Started

Prerequisites

No outside dependencies are required, outside of a C compiler and Make.

Installation

1. Clone the repo

   git clone https://github.com/travmatth/ft_ssl.git

2. Compile ft_ssl

   make

Usage

export DES_KEY="C0FFEE69DEADBEEF"
export DES_IV=0011223344556677

echo "We can encode base64" | ./ft_ssl base64
echo "And decode it" | ./ft_ssl base64 | ./ft_ssl base64 -d
echo "We can encrypt with DES3" |  ./ft_ssl des3 -a -k "$DES_KEY" -v "$DES_IV" -o out.txt
# and decrypt it
./ft_ssl des3 -a -k "$DES_KEY" -v "$DES_IV" -i out.txt -d
./ft_ssl des3 -p "we can also generate secure keys using scrypt"
