You asked how to check if a file is corrupted.

Store a checksum of the encrypted file, best together with the file, maybe appended to the end.

If you meant something different, you may want to try to explain it...

update

btw: Trying to decrypt it should be enough, I'm not aware of any common encryption which can be reversed if corrupted.
