====== Encrypt Files ======

**A single file**

Encrypt and decrypt:

  openssl aes-256-cbc -salt -in file -out file.aes

  openssl aes-256-cbc -d -salt -in file.aes -out file
  
Note that the file can of course be a tar archive.

**tar and encrypt a whole directory**

  tar -cf - directory | openssl aes-256-cbc -salt -out directory.tar.aes

  openssl aes-256-cbc -d -salt -in directory.tar.aes | tar -x -f -
  
**tar zip and encrypt a whole directory**

  tar -zcf - directory | openssl aes-256-cbc -salt -out directory.tar.gz.aes

  openssl aes-256-cbc -d -salt -in directory.tar.gz.aes | tar -xz -f -
  
**Password from file option**
<code>
-pass file:<passwdfile>
</code>
