Description

rsatools is a program for encrypting and decrypting files with the RSA algorithm. When you have installed rsatools then you must at first create a publickey and a privatekey file. The data will be encrypted with the publickey file and decrypted with the privatekey file. The longer the key is the moresecure it is. You must specify the length of the key in bits. Usually 1024 bits is enough.

Features

• uses the RSA algorithm
• variable key length
• can encrypt and decrypt any files (binaries too)

History

To do

• test it under *BSD and other Unixes
• port it to other platforms (Windows: /dev/urandom (?), FileExists)
• don't open the files for writing when an error occurs
• make a -f option that overwrites existing files

• don't store the plainfile in the memory

Requirements

• Unix (with a random engine like /dev/urandom)
• GMP library (http://www.swox.com/gmp/)
