Encrypt/Decrypt string with password by openssl
`openssl-cipher` is a library to encrypt/decrypt string or file with
`openssl` command.
## Install:
1. Install `openssl` command to your system by
apt, yum... whatever you desire.
Source code: http://www.openssl.org/source/
2. Put this file into load-path'ed directory, and byte compile it
if desired. And put the following expression into your ~/.emacs.
(require 'openssl-cipher)
## Usage:
* To encrypt a well encoded string (High level API)
`openssl-cipher-encrypt-string` <-> `openssl-cipher-decrypt-string`
* To encrypt a binary string (Middle level API)
`openssl-cipher-encrypt-unibytes` <-> `openssl-cipher-decrypt-unibytes`
* To encrypt a binary string (Low level API)
`openssl-cipher-encrypt` <-> `openssl-cipher-decrypt`
* To encrypt a file
`openssl-cipher-encrypt-file` <-> `openssl-cipher-decrypt-file`
## Sample:
* To encrypt my secret
Please ensure that do not forget `clear-string` you want to hide.
(defvar my-secret nil)
(let ((raw-string "My Secret"))
(setq my-secret (openssl-cipher-encrypt-string raw-string))
(clear-string raw-string))
* To decrypt `my-secret`
(openssl-cipher-decrypt-string my-secret)
