SCrypt

scrypt in accordance with RFC 7914. Directly implements the KDF interface.

Parameters:

• CPU/memory cost parameter; must be a positive power of two greater than 1; controls how many independent transformations of the input must be held in memory

• affects: scryptBlockMix

• parallelization parameter; must be >=1; controls how many blocks scryptROMix is run on in parallel

• affects: final key derivation

• blockSize factor; must be >=1; fine-tunes sequential memory read size and performance. Defaults to 8, which is commonly used.

• affects: scryptBlockMix and scryptROMix
