Base64 is just a simple encoding algorithm, completely lossless and with a unique output for every unique input. In other words, base64(somestring) != base64(someotherstring) always holds true. Maybe you are confusing it with destructive cryptographic functions like MD5 ? Sven Johansson Twitter: @svjson
