py3-cryptodomex-3.23.0

PyCryptodome is a self-contained Python package of low-level cryptographic primitives. It is an cleaned and simplified fork of PyCrypto, exposing almost the same API. Most applications run unmodified, apart from a very few compatibility breaks for those parts of the API that represented a security hazard or that were too hard to maintain. 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. PyCryptodomeX provides the same library as PyCryptodome but under the Cryptodome module name rather than Crypto. As well as functionality supported by PyCrypto, this adds support for: - Authenticated encryption modes (GCM, CCM, EAX, SIV, OCB) - Elliptic curves cryptography (NIST P-256 curve only) - SHA-3 (including SHAKE XOFs), SHA-512/t and BLAKE2 hash algorithms - Salsa20 and ChaCha20 stream ciphers - scrypt and HKDF - Deterministic (EC)DSA
