python3-pycryptodomex (Python Cryptography Toolkit)

PyCryptodome is a self-contained Python package of low-level

cryptographic primitives. PyCryptodome is a fork of PyCrypto.

PyCryptodome is not a wrapper to a separate C library like OpenSSL.

To the largest possible extent, algorithms are implemented in pure

Python. Only the pieces that are extremely critical to performance

(e.g. block ciphers) are implemented as C extensions.
