RSA Implementation by Querdos

An implementation of the RSA algorithm according to PKCS#1

Prerequisits

This implementation use the well known library Gnu Multiple Precision (GMP).

Usage

Three possibilities:

• Generate a key-pair

  ./rsa --generate-key-pair

  If the .rsa directory doesn't exists, it will create it and generate 2 files in it: rsa.priv and rsa.pub

• Encrypt a file

  ./rsa --encrypt file

  It requires that the --generate-key-pair has been used before. Otherwise, will raise an error.

• Decrypt a file

  ./rsa --decrypt file

  It requires that the --generate-key-pair has been used before. Otherwise, will raise an error.
