The encryption app that we are using seems to generate the same output for the same input. That is bad right? I'm not smart enough to understand the scheme being used though.
The string is apparently how the app stores the password (hash?) for the encrypted files generated by the app. If we use the same password for different files, then the same string appears in the header of the file.
