%global _description %{expand: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.}
