Parameters

key

Type: SystemByte
The key to derive from.

salt

Type: SystemByte
The salt. A unique salt means a unique SCrypt stream, even if the original key is identical.

cost

Type: SystemInt32
The cost parameter, typically a fairly large number such as 262144. Memory usage and CPU time scale approximately linearly with this parameter.

blockSize

Type: SystemInt32
The mixing block size, typically 8. Memory usage and CPU time scale approximately linearly with this parameter.

parallel

Type: SystemInt32
The level of parallelism, typically 1. CPU time scales approximately linearly with this parameter.

maxThreads

Type: SystemNullableInt32
The maximum number of threads to spawn to derive the key. This is limited by the parallel value. null will use as many threads as possible.

derivedKeyLength

Type: SystemInt32
The desired length of the derived key.
