• 加密

#!/bin/bash

ori=$(pwd)
cd $(dirname $1)
if [ $2 ]; then
  tar -zcf - $(basename $1) | openssl aes256 -salt -md sha256 > $ori/$2
else
  echo Must specify the name of output file
fi      

• 解密

#!/bin/bash

if [ $2 ]; then
  cat $1 | openssl aes256 -md sha256 -d | tar zx -C $2
else
  cat $1 | openssl aes256 -md sha256 -d | tar zx
fi
