NAME
       zipcloak - encrypt entries in a zipfile

SYNOPSIS
       zipcloak [-d] [-b path] [-Ofile] [-Yem] [-h] [-v] [-L] zipfile

ARGUMENTS
       zipfile  Zipfile to encrypt entries in

OPTIONS
       -b path
       --temp-path path
              Use the directory given by path for the temporary zip file.

       -d
       --decrypt
              Decrypt encrypted entries (copy if given wrong password).

       -h
       --help
              Show a short help.

       -L
       --license
              Show software license.

       -O path
       --output-file zipfile
              Write output to new archive zipfile, leaving original archive as
              is.

       -q
       --quiet
              Quiet operation.  Suppresses some informational messages.

       -v
       --version
              Show version information.

       -Y em
       --encryption-method em
              Set the encryption method.  Supported  methods  are  Traditional
              (weak),  and  WinZip-compatible  AES  (strong)  with various key
              lengths: AES128, AES192, and AES256.   AES  encryption  must  be
              enabled  at  build  time,  and requires a compatible AES library
              kit.  An AES-capable UnZip program is  needed  to  extract  AES-
              encrypted entries.

DESCRIPTION
       zipcloak  encrypts all unencrypted entries in the zipfile.  This is the
       default action.

       The -d option is used to decrypt encrypted entries in the zipfile.

       zipcloak uses original zip encryption which is considered weak.

       Note:  The encryption code of this program is not  copyrighted  and  is
              put  in  the public domain.  It was originally written in Europe
              and can be freely distributed from  any  country  including  the
              U.S.A.  (Previously if this program was imported into the U.S.A,
              it could not be re-exported from the U.S.A to another  country.)
              See  the  file README.CR included in the source distribution for
              more on this.  Otherwise, the Info-ZIP license applies.

EXAMPLES
       To be added.

BUGS
       Large files (> 2 GB) and large archives not yet supported.

       Split archives not yet supported.  A work  around  is  to  convert  the
       split  archive to a single-file archive using zip and then use zipcloak
       on the single-file archive.  If needed, the resulting archive can  then
       be split again using zip.
