Python high level library for symmetric & asymmetric encryption

Project description

cryptidy

Python high level library for symmetric & asymmetric encryption

License Percentage of issues still open Maintainability codecov linux-tests windows-tests GitHub Release

This library has been written to make encryption / decryption of any python object as simple as possible, while keeping the encryption solution secure. It is based on pycryptodomex AES and RSA encrpytion implementations.

It's main features are:

  • Encrypt any pickable Python object / variable / blob
  • Add an UTC timestamp to the encrypted message
  • Verify that decrypted messages timestamps aren't in the future or too old (for bad RTC clock diags)
  • Allow symmetric encryption (AES-EAX mode)
    • 128, 192 or 256 bits encryption
  • Allow asymmetric encryption (RSA encryption with SHA384 hash algorithm and above AES encryption)
    • 1024, 2048 or 4096 bits RSA encryption with AES-256 session encryption
  • Provide the encypted data as base64 string for maximum portability between platforms and encodings
  • Unload AES key from memory as soon as possible to help prevent memory attacks

Setup

Current cryptidy tests are Python 3.7 and up.
Nevertheless, cryptidy v1.2.3 still runs on Python 2.7+ ;)

pip install cryptidy

Symmetric encryption usage

from cryptidy import symmetric_encryption

key = symmetric_encryption.generate_key(32)  # 32 bytes == 256 bits

some_python_objects = ['foo', 'bar'], 'some long string', 12
encrypted = symmetric_encryption.encrypt_message(some_python_objects, key)
timestamp, original_object = symmetric_encryption.decrypt_message(encrypted, key)

Asymmetric encryption usage

from cryptidy import asymmetric_encryption

priv_key, pub_key = asymmetric_encryption.generate_keys(2048)  # 2048 bits RSA key

some_python_objects = ['foo', 'bar'], 'some long string', 12
encrypted = asymmetric_encryption.encrypt_message(some_python_objects, pub_key)
timestamp, original_object = asymmetric_encryption.decrypt_message(encrypted, priv_key)
