Scrypt(Int32, ImmutableArray<Byte>, Int32, Int32, Int32)

Configures parameters of Scrypt.

Declaration

public Scrypt(int cost, in ImmutableArray<byte> salt, int keyLength, int parallelization, int blockSize)

Parameters

Type	Name	Description
Int32	cost	The CPU/memory cost parameter. Corresponds to `n`.
ImmutableArray<Byte>	salt	A cryptographic salt.
Int32	keyLength	The desired byte-length of the derived key. Corresponds to `dkLen` except that it's not bit-wise but byte-wise.
Int32	parallelization	The parallelization parameter. Corresponds to `p`.
Int32	blockSize	The blocksize parameter. Corresponds to `r`.
