Encrypt and decrypt files in AES Crypt format (version 2)
pyAesCrypt is a Python 3 file-encryption module and script that uses AES256-CBC to encrypt/decrypt files.
The script is Free Software, released under the Apache License, Version 2.0.
pyAesCrypt is brought to you by Marco Bellaccini - marco.bellaccini(at!)gmail.com.
IMPORTANT SECURITY NOTE: version 2 of the AES Crypt file format does not authenticate the “file size modulo 16” byte. This implies that an attacker with write access to the encrypted file may alter the corresponding plaintext file size by up to 15 bytes.
NOTE: there is no low-level memory management in Python, hence it is not possible to wipe memory areas were sensitive information was stored.
Module usage example
Here is an example showing encryption and decryption of a file:
import pyAesCrypt # encryption/decryption buffer size - 64K bufferSize = 64 * 1024 password = "foopassword" # encrypt pyAesCrypt.encryptFile("data.txt", "data.txt.aes", password, bufferSize) # decrypt pyAesCrypt.decryptFile("data.txt.aes", "dataout.txt", password, bufferSize)
Script usage examples
Encrypt file test.txt in test.txt.aes:
pyAesCrypt -e test.txt
Decrypt file test.txt.aes in test.txt:
pyAesCrypt -d test.txt.aes
Encrypt file test.txt in test2.txt.aes:
pyAesCrypt -e test.txt -o test2.txt.aes
Decrypt file test.txt.aes in test2.txt:
pyAesCrypt -d test.txt.aes -o test2.txt
