 820 @itemize
 821 @item Authenticated encryption modes (GCM, CCM, EAX, SIV, OCB)
 822 @item Accelerated AES on Intel platforms via AES-NI
 823 @item First class support for PyPy
 824 @item Elliptic curves cryptography (NIST P-256 curve only)
 825 @item Better and more compact API (nonce and iv attributes for ciphers,
 826 automatic generation of random nonces and IVs, simplified CTR cipher mode, and
 827 more)
 828 @item SHA-3 (including SHAKE XOFs) and BLAKE2 hash algorithms
 829 @item Salsa20 and ChaCha20 stream ciphers
 830 @item scrypt and HKDF
 831 @item Deterministic (EC)DSA
 832 @item Password-protected PKCS#8 key containers
 833 @item Shamir’s Secret Sharing scheme
 834 @item Random numbers get sourced directly from the OS (and not from a CSPRNG
 835 in userspace)
 836 @item Cleaner RSA and DSA key generation (largely based on FIPS 186-4)
 837 @item Major clean ups and simplification of the code base
