Class Encrypt

java.lang.Object
  de.schlichtherle.Encrypt

Direct Known Subclasses:

encrypt

public class Encrypt
extends Object

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

Please note that you should not use this utility to encrypt a plain ZIP file to an RAES encrypted ZIP file (usually a files with a ".tzp" or ".zip.rae" suffix). 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 encrypt a plain ZIP file to an RAES encrypted ZIP file, use the "cp" command of the nzip class instead. This class knows about the correct character sets for the various flavours of ZIP compatible files.
