Package org.bouncycastle.crypto.examples

Class DESExample

  • public class DESExample
extends java.lang.Object
    DESExample is a simple DES based encryptor/decryptor.

    The program is command line driven, with the input and output files specified on the command line. 

     java org.bouncycastle.crypto.examples.DESExample infile outfile [keyfile]
    A new key is generated for each encryption, if key is not specified, then the example will assume encryption is required, and as output create deskey.dat in the current directory. This key is a hex encoded byte-stream that is used for the decryption. The output file is Hex encoded, 60 characters wide text file.

    When encrypting;

    • the infile is expected to be a byte stream (text or binary)
    • there is no keyfile specified on the input line

    When decrypting;

    • the infile is expected to be the 60 character wide base64 encoded file
    • the keyfile is expected to be a base64 encoded file

    This example shows how to use the light-weight API, DES and the filesystem for message encryption and decryption.
