Description
[Make check method in FormatPreservingEncryption protected]
Why is this needed?
[If the check method was protected I could extend the class and add some additional checks for example maybe based on regular expressions on a need basis]
Additional Information
[Since the class is not marked as final I assume there is no harm in allowing this. Do pls note new to this project. In case there is another way to achieve this please advise. Thanks]
