crypto.checkPrime(candidate[, options], callback)

• candidate <ArrayBuffer> | <SharedArrayBuffer> | <TypedArray> | <Buffer> | <DataView> | <bigint> 编码为任意长度的大端字节序序列的可能素数。

  ¥candidate <ArrayBuffer> | <SharedArrayBuffer> | <TypedArray> | <Buffer> | <DataView> | <bigint> A possible prime encoded as a sequence of big endian octets of arbitrary length.

• options <Object>

  • checks <number> 要执行的 Miller-Rabin 概率素性迭代次数。当值为 0（零）时，将使用多次检查，对于随机输入产生最多 2^-64 的误报率。选择多个检查时必须小心。有关更多详细信息，请参阅 BN_is_prime_ex 函数 nchecks 选项的 OpenSSL 文档。默认值：0

    ¥checks <number> 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. Default: 0

• callback <Function>

  • err <Error> 如果检查期间发生错误，则设置为 <Error> 对象。

    ¥err <Error> Set to an <Error> object if an error occurred during check.

  • result <boolean> 如果候选者是错误概率小于 0.25 ** options.checks 的素数，则为 true。

    ¥result <boolean> true if the candidate is a prime with an error probability less than 0.25 ** options.checks.

检查 candidate 的素性。

¥Checks the primality of the candidate.
