Class Decrypt

      de.schlichtherle.io.samples.Decrypt

public class Decrypt
extends CommandLineUtility

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.
