Scrypt class

A class for performing scrypt key derivation.

Scrypt is a key derivation function designed to be secure against both hardware and software attacks. It is commonly used for securely deriving encryption keys from user-provided passwords.

Fields:

  • _xy: A list of 32-bit unsigned integers representing intermediate data during scrypt key derivation.
  • _v: A list of 32-bit unsigned integers representing additional intermediate data during scrypt key derivation.
  • n: An integer representing the CPU/memory cost parameter. It defines the general work factor for scrypt.
  • r: An integer representing the block size parameter, which specifies the number of iterations and memory size used.
  • p: An integer representing the parallelization parameter, which controls the amount of parallel processing.

Constructors

Scrypt(int n, int r, int p)
Creates a new Scrypt instance for key derivation.
