   jencrypt - jEncrypt is a file encryption archiver designed to help you
              encrypt files and directories into a single file archive.


   Synopsis
   --------
   jencrypt -e, --enc [File or folder to encrypt] [Destination file]
            -d, --dec [File to decrypt] [Destination folder]
            -p, --pwd [Password to use for en-/decryption]


   Meta information
   ----------------
   Interface             : command line
   Source language       : J2SE 7.0
   Use requirements      : Java Runtime Environment 7.0
                           Java Cryptography Extension 7.0 (enables support
                           for keys larger than 128 bits)


   Description
   -----------
   jEncrypt encrypts and decrypts files using the Java Cryptographic
   Extension (JCE) framework. 

   To use key strenghts above 128 bits with Oracle's Java software, Oracle
   provides unlimited strength policy files. The folder shell\UnlockJCE
   contains an installer for Windows XP/7 which makes backups of the
   existing policy files and installs the JCE unlimited strength policy
   files automatically to the correct folders.


   Security
   --------
   jEncrypt encrypts data with the AES-CTR mode which was first recommended
   by the National Institute of Standards and Technology in 2001 (NIST SP
   800-38A).

   The AES-CTR mode only provides confidentiality; to ensure an encrypted
   message is not accidentally modified, or maliciously tampered with, a
   separate message authentication code is required which jEncrypt
   currently does not provide.

         [Destination file].

   -dec  Decrypt [File to decrypt] to the folder [Destination folder].

   -pwd  Password from which the encryption key will be derived.

   -ini  Full path to the configuration file.

   All other parameters are configured and documented in jencrypt.ini.


   Exit codes
