## 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***.**
