Pbkdf2(Int32, in ImmutableArray<Byte>, Int32)

Configures parameters of PBKDF2.

Declaration

public Pbkdf2(int iterations, in ImmutableArray<byte> salt, int keyLength)

Parameters

Type	Name	Description
Int32	iterations	The number of iterations desired. Corresponds to `c`.
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.
