+It brings the following enhancements with respect to the last official version
+of PyCrypto:
+
address@hidden
address@hidden Authenticated encryption modes (GCM, CCM, EAX, SIV, OCB)
address@hidden Accelerated AES on Intel platforms via AES-NI
address@hidden First class support for PyPy
address@hidden Elliptic curves cryptography (NIST P-256 curve only)
address@hidden Better and more compact API (nonce and iv attributes for ciphers,
+automatic generation of random nonces and IVs, simplified CTR cipher mode, and
+more)
address@hidden SHA-3 (including SHAKE XOFs) and BLAKE2 hash algorithms
address@hidden Salsa20 and ChaCha20 stream ciphers
address@hidden scrypt and HKDF
address@hidden Deterministic (EC)DSA
address@hidden Password-protected PKCS#8 key containers
address@hidden Shamir’s Secret Sharing scheme
address@hidden Random numbers get sourced directly from the OS (and not from a 
CSPRNG
+in userspace)
address@hidden Cleaner RSA and DSA key generation (largely based on FIPS 186-4)
address@hidden Major clean ups and simplification of the code base
address@hidden itemize\n")
