Either convert your encrypted data to strings or pass the length along with the data through your code paths. You can only use 'strlen' on something that you know is in fact a string. The encrypted data is *not* a string, it's a chunk of arbitrary bytes. The result of calling 'strlen' on it is effectively random. There is no way to know how many bytes it holds just from looking at the data -- you need to store that separately.
