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?
