%description -n python3-%{pypi_name}
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.
