de.schlichtherle.truezip.sample.file.app
Class Decrypt

java.lang.Object
  de.schlichtherle.truezip.file.TApplication<RuntimeException>

public class Decrypt
extends Application
extends Application

Decrypts the contents of the RAES file provided as the first argument into the file provided as the second argument for the main method.

Please note that you should not use this utility to decrypt an RAES encrypted ZIP file (usually a file with a ".tzp" or ".zip.rae" suffix) back to a plain ZIP file. This is because RAES encrypted ZIP files use the "UTF-8" as their character set, whereas plain ZIP files use "IBM437", a.k.a. "CP437". To decrypt an RAES encrypted ZIP file to a plain ZIP file, use the cp command of the Nzip class instead. This class knows about the correct character set charsets for the various flavours of ZIP compatible files.

public static void main(String[] args)
                 throws FsSyncException

Equivalent to System.exit(new Decrypt().run(args));.

Throws:: FsSyncException

runChecked

Description copied from class: Application

Runs this command line utility. Throws an exception if an error occurs.

Avoid repeating this method and updating the same archive file upon each call! This would degrade the overall performance from O(n) to O(m*n), where m is the number of new or modified entries and n is the number of all entries in the archive file!

Specified by:: runChecked in class Application

Parameters:: args - an array of arguments for this command line utility.
Returns:: A negative integer in order to continue calling this method in a loop. Otherwise, the return value is used as the exit status of the VM.
Throws:: Application.IllegalUsageException - on any exception.; IOException
