History backend that can encrypt the xonsh shell commands history.

History backend that encrypt the xonsh shell commands history file
to prevent leaking sensitive data from the commands history
(keys, passwords, hosts, names).

Installation

To install use pip:

xpip install xontrib-history-encrypt
# or: xpip install -U git+https://github.com/anki-code/xontrib-history-encrypt

Usage: supported encryption

Base64 (default)

Base64 is not the real encrypter and implemented as fast way to encode history file and for education reasons. It can save you from the massive scanning the file system for keywords (i.e. password, key) as well as reading the history file by not experienced user. But it can be decoded in five minutes by the professional.

# Add to xonsh RC file
$XONSH_HISTORY_ENCRYPTOR = 'base64'
xontrib load history_encrypt

Fernet

The implementation of Fernet (AES CBC + HMAC) that was strongly recommended on stackoverflow. On first start it generates a key that you should save in secure place. Than you can use this key to decrypt the history.

# Add to xonsh RC file
$XONSH_HISTORY_ENCRYPTOR = 'fernet'
xontrib load history_encrypt

Custom

from xontrib.history_encrypt.fernet import *

$XONSH_HISTORY_ENCRYPTOR = {
  'key': fernet_key,
  'enc': lambda data, key: fernet_encrypt(data.encode(), key).decode(),
  'dec': lambda data, key: fernet_decrypt(data.encode(), key).decode()  
}
xontrib load history_encrypt

How to check the backend is working

Some points about the backend

• At start the backend read and decrypt all commands and this could take time. Basically we assume that you will use the xontrib on your servers and haven't so big history.

• The commands are stored in the memory and flush to the disk at the exit from the shell. If the shell has crash there is no flushing to the disk and commands will be lost. Use history flush command if you plan to run something experimental.

• The backend has minimal history management support in comparing with json or sqlite backends and you can find the lack of features.
