"Warning: mcrypt_encrypt(): Key of size XX not supported by this algorithm. Only keys of size 24 supported in"

If you receive this error when you use an Encryption password to encrypt a file or backup via automation services like Clientexec Database backup, it is likely that the encryption password is set to less than 24 characters.

With PHP version 5.6, the password will need to be at least 24 characters.
