Node crypto.checkPrimeSync function | API Reference | Bun

Checks the primality of the candidate.

A possible prime encoded as a sequence of big endian octets of arbitrary length.

true if the candidate is a prime with an error probability less than 0.25 ** options.checks.

The number of Miller-Rabin probabilistic primality iterations to perform. When the value is 0 (zero), a number of checks is used that yields a false positive rate of at most 2**-64 for random input. Care must be used when selecting a number of checks. Refer to the OpenSSL documentation for the BN_is_prime_ex function nchecks options for more details.
