Encryption produces gibberish string

You’ll notice that the createKey() method outputs binary data, which is hard to deal with (i.e., a copy-paste may damage it), so you may use bin2hex(), or base64_encode to work with the key in a more friendly manner.

You might find the same technique useful for the results of encryption:

Code:

// Encrypt some text & make the results text
$encoded = base64_encode($encrypter->encrypt($plaintext));

I think you have the base64_encode in the wrong place.



I figured it out, thanks.
