RC4 BASE64 encryptor

Script submitted by Franck Couvy. Download the script.

This uses Base64 and RC4 encrytion. It uses symmetric passwords, so it is not suitable for encrypting web data from browser to server, but can be used from server to browser. It could be cracked using brute force, but accepts very long passwords (upto 256 characters), making that difficult or time consuming to do. As an added benefit, it makes the output completely incomprehensible with even small variations in decrytion keys.

Enter some text to encrypt/decrypt

Password:

To encrypt:
output = (new Rc4B64Class()).Encrypt('Plain text','password');
To decrypt:
output = (new Rc4B64Class()).Decrypt('Encrypted text','password');
