Crate crypto_primes

Prime number tools for crypto-bigint

This library implements prime number generation and primality checking for crypto-bigint integers. In particular:

• Generating random primes and safe primes of given bit size;
• Sieving iterator and one-time trial division by small integers;
• Miller-Rabin test;
• Strong and extra strong Lucas tests, and Lucas-V test.

See the documentation for the specific tests for more information and references.

Modules

• hazmat
  Components to build your own primality test. Handle with care.

Traits

• RandomPrimeWithRng
  Provides a generic way to access methods for random prime number generation and primality checking, wrapping the standalone functions (is_prime_with_rng etc).

Functions

• is_primedefault-rng
  Checks probabilistically if the given number is prime using OsRng as the RNG.
• is_prime_with_rng
  Checks probabilistically if the given number is prime using the provided RNG.
• is_safe_primedefault-rng
  Checks probabilistically if the given number is a safe prime (that is, such that (n - 1) / 2 is also prime) using OsRng as the RNG.
• is_safe_prime_with_rng
  Checks probabilistically if the given number is a safe prime using the provided RNG.
• primedefault-rng
  Returns a random prime of size bit_length using OsRng as the RNG.
• prime_with_rng
  Returns a random prime of size bit_length using the provided RNG.
• safe_primedefault-rng
  Returns a random safe prime (that is, such that (n - 1) / 2 is also prime) of size bit_length using OsRng as the RNG.
• safe_prime_with_rng
  Returns a random safe prime (that is, such that (n - 1) / 2 is also prime) of size bit_length using the provided RNG.
