%global _description \
PyCryptodome 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 curve 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) and BLAKE2 hash algorithms\
* Salsa20 and ChaCha20 stream ciphers\
* scrypt and HKDF\
* 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)\
* Cleaner RSA and DSA key generation (largely based on FIPS 186-4)\
* Major clean ups and simplification of the code base\
\
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.
