Description:

PyCryptodomex is a fork of PyCrypto. It brings the following
enhancements with respect to the last official version of PyCrypto
(2.6.1):
- Authenticated encryption modes (GCM, CCM, EAX, SIV, OCB)
- Accelerated AES on Intel platforms via AES-NI
- First class support for PyPy
- Elliptic curves cryptography (NIST P-256, P-384 and P-521 curves
only)
- Better and more compact API (nonce and iv attributes for ciphers,
automatic generation of random nonces and IVs, simplified CTR cipher
mode, and more)
- SHA-3 (including SHAKE XOFs), truncated SHA-512 and BLAKE2 hash
algorithms
- Salsa20 and ChaCha20/XChaCha20 stream ciphers
- Poly1305 MAC
- ChaCha20-Poly1305 and XChaCha20-Poly1305 authenticated ciphers
- scrypt, bcrypt and HKDF derivation functions
- Deterministic (EC)DSA
- Password-protected PKCS#8 key containers
- Shamir's Secret Sharing scheme
- Random numbers get sourced directly from the OS (and not from a
CSPRNG in userspace)
- Simplified install process, including better support for Windows
- Cleaner RSA and DSA key generation (largely based on FIPS 186-4)
- Major clean ups and simplification of the code base
