Re: Problems with cipher behavior

FYI: I haven't used that behaviour at all. :)

The errors you pasted look like encoding issues. You might be
encrypting data into a field that can't handle the input.
mypassword is a good varchar(255) but my password ciphered might
require a blob or at least some other charset.

When I wrote my own "mini-cipher" I god pure binary data back from
Cakes Security::cipher() and had to hex-encode the data before I could
save it to the database. I also had to do the reverse when reading the
data back. This was kind of a last-minute hack and I did not like to
alter the database-schema of a live application.

This is nothing advanced so here is my code as an example:

function _encrypt($str) {
$out = bin2hex(Security::cipher( $str, 'some salt' ));
return $out;
}
function _decrypt($str) {
$out = Security::cipher(pack('H*', $str), 'some salt' );
return $out;
}

After encryption it is bin2hexed and before decryption is is returned
to binary data.
