Layanan Kriptografi
*******************

Modul-modul yang dideskripsikan di bagian ini mengimplementasikan
berbagai algoritma dunia kriptografi. Mereka (modul-modul) tersedia
bebas saat pemasangan. Pada sistem Unix, modul "crypt" mungkin saja
tersedia. Berikut ini ikhtisar:

* "hashlib" --- Secure hashes and message digests

  * Hash algorithms

  * SHAKE variable length digests

  * Key derivation

  * BLAKE2

    * Creating hash objects

    * Konstanta

    * Contoh-contoh

      * Simple hashing

      * Using different digest sizes

      * Keyed hashing

      * Randomized hashing

      * Personalization

      * Tree mode

    * Credits

* "hmac" --- Keyed-Hashing for Message Authentication

* "secrets" --- Generate secure random numbers for managing secrets

  * Random numbers

  * Generating tokens

    * How many bytes should tokens use?

  * Other functions

  * Recipes and best practices
