allows one to easily encrypt and decrypt files symmetrically using openssl and python3

Project description

fileenc-openssl

This code allows one to easily encrypt and decrypt files symmetrically using openssl and python3.

Uses aes-256-cbc for file encryption, with salt, sha256 key stretching and sha256 checksum.

Installation

You can install using

pip install fileenc-openssl

Usage

From command line:

fileenc --key 'password123' --input '*.png' --check --overwrite
filedec --key 'password123' --input '*.png.enc' --check --overwrite --remove

From python:

from fileenc_openssl import stretch_key, encrypt_file, decrypt_file
stretched_key = stretch_key('password123')
enc_pth = encrypt_file(raw_pth, key=stretched_key)
res_pth = decrypt_file(enc_pth, key=stretched_key)

Testing (needs py.test):

py.test

Options

You can find all options using fileenc --help:

-h, --help              show this help message and exit
-k KEY, --key KEY       the key to use for encryption
-i INP, --input INP     input file, directory or pattern (as a single string) (.enc will be appended)
-o OUTP, --output OUTP  optionally, output file or directory (.enc will be stripped if available)
-d, --decrypt           decrypt the input file(s) (as opposed to encrypt,       which is the default)
-f, --overwrite         overwrite existing files when decrypting (encrypting always overwrites)
-r, --remove            remove the input file after en/decrypting (after --check)
-t, --check             test the encryption/decryption by reversing it (abort on failure)

Future

  • Multiprocessing for multiple files
  • Faster checksum algorithm?
