Gibberish AES

A Javascript library for OpenSSL compatible AES encryption

Deprecation Notice

This library is a quite old, and uses an older and non-authenticated cipher mode, CBC. There are better and more frequently maintained alternatives. Here are a couple that I would recommend:

Usage

    // GibberishAES.enc(string, password)
    // Defaults to 256 bit encryption
    enc = GibberishAES.enc("This sentence is super secret", "ultra-strong-password");
    alert(enc);
    GibberishAES.dec(enc, "ultra-strong-password");

    // Now change size to 128 bits
    GibberishAES.size(128);
    enc = GibberishAES.enc("This sentence is not so secret", "1234");
    GibberishAES.dec(enc, "1234");

    // And finally 192 bits
    GibberishAES.size(192);
    enc = GibberishAES.enc("I can't decide!!!", "whatever");
    GibberishAES.dec(enc, "whatever");

OpenSSL Interop

In Javascript

GibberishAES.enc("Made with Gibberish\n", "password");
// Outputs: "U2FsdGVkX1+21O5RB08bavFTq7Yq/gChmXrO3f00tvJaT55A5pPvqw0zFVnHSW1o"

On the command line

echo "U2FsdGVkX1+21O5RB08bavFTq7Yq/gChmXrO3f00tvJaT55A5pPvqw0zFVnHSW1o" | openssl enc -d -aes-256-cbc -a -k password -md md5

Requirements

None.

The library is fully encapsulated, you should be able to drop it into nearly any website. The downside to this is that it grew with the addition of its own Base64 library and MD5 hashing algorithm.

Tests

The test script does require JQuery(included), but the basic GibberishAES does not.

Design Factors

It only supports CBC AES encryption mode, and it's built to be compatible with OpenSSL.
