crypto.scryptSync(password, salt, keylen[, options])

• password <string> | <Buffer> | <TypedArray> | <DataView>
• salt <string> | <Buffer> | <TypedArray> | <DataView>
• keylen <number>
• options <Object>
  • cost <number> CPU/内存消耗参数。必须是大于一的二的幂。默认值： 16384。
  • blockSize <number> 块大小参数。默认值： 8。
  • parallelization <number> 并行化参数。默认值： 1。
  • N <number> 是 cost 的别名。两者只能指定一个。
  • r <number> blockSize 的别名。两者只能指定其一。
  • p <number> parallelization 的别名。两者只能指定其一。
  • maxmem <number> 内存上限。当 (大约) 128 * N * r > maxmem 时，会发生错误。默认值： 32 * 1024 * 1024。
• 返回：<Buffer>

提供同步 scrypt 实现。Scrypt 是一种基于密码的密钥派生函数，设计上在计算和内存方面成本很高，以使暴力破解攻击得不到回报。

🌐 Provides a synchronous scrypt implementation. Scrypt is a password-based key derivation function that is designed to be expensive computationally and memory-wise in order to make brute-force attacks unrewarding.

salt 应尽可能唯一。建议盐值是随机的，并且至少为 16 字节长。详情请参阅 NIST SP 800-132。

🌐 The salt should be as unique as possible. It is recommended that a salt is random and at least 16 bytes long. See NIST SP 800-132 for details.

在传递 password 或 salt 字符串时，请考虑 将字符串用作加密 API 输入时的注意事项。

🌐 When passing strings for password or salt, please consider caveats when using strings as inputs to cryptographic APIs.

当密钥派生失败时，会抛出异常，否则派生的密钥将作为 Buffer 返回。

🌐 An exception is thrown when key derivation fails, otherwise the derived key is returned as a Buffer.

当任何输入参数指定无效的值或类型时，会抛出异常。

🌐 An exception is thrown when any of the input arguments specify invalid values or types.
