%global common_summary A self-contained cryptographic library for Python
%global common_description PyCryptodome is a self-contained Python package of low-level\
cryptographic primitives. It's a fork of PyCrypto. It brings several\
enhancements with respect to the last official version of PyCrypto\
(2.6.1), for instance:\
\
  * Authenticated encryption modes (GCM, CCM, EAX, SIV, OCB)\
  * Accelerated AES on Intel platforms via AES-NI\
  * 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.\
\
Note: all modules are installed under the Cryptodome package to avoid\
conflicts with the PyCrypto library.
