FileSafe -- A simple Ruby script for encrypting/decrypting files using 256-bit AES and a master key derived from a password/passphrase via the PBKDF2 function.I wrote this script for use on several systems where I needed to regularly encrypt/decrypt one or more files using a password or passphrase. The method used should be reasonably secure for the uses I required. I have NOT adapted the script (yet) for non-POSIX environments (Windows) however. This script was written and tested using Ruby 1.9.x. No attempts to adapt or test it under earlier Ruby versions were made. It requires/relies on: OpenSSL (encryption/HMAC/hash algorithms), securerandom (cryptographically secure random data), the pbkdf2 gem (for the password-based key derivitive function PBKDF2), the highline gem (for reading a password/passphrase from a terminal), and tempfile for temporary file creation. Latest VersionThe latest version is version 3.0.0 released on 29 Oct. 2011. You can download the latest gem (3.0.0) here: SHA256 and MD5 sums of the gem are:
