套件：python3-pycryptodome（3.20.0 dfsg-3）

cryptographic Python library (Python 3)

PyCryptodome is a self-contained Python package of low-level cryptographic primitives.

PyCryptodome is 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, P-384 and P-521 curves 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 and cSHAKE XOFs), truncated SHA-512 and BLAKE2
    hash algorithms
  * Salsa20 and ChaCha20/XChaCha20 stream ciphers
  * Poly1305 MAC
  * ChaCha20-Poly1305 and XChaCha20-Poly1305 authenticated ciphers
  * scrypt, bcrypt and HKDF derivation functions
  * 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.

This is the Python 3 version of the package.
