public static final class Protos.ScryptParameters
extends com.google.protobuf.GeneratedMessage
implements Protos.ScryptParametersOrBuilder

Protobuf type wallet.ScryptParameters

 The parameters used in the scrypt key derivation function.
  The default values are taken from http://www.tarsnap.com/scrypt/scrypt-slides.pdf.
  They can be increased - n is the number of iterations performed and
  r and p can be used to tweak the algorithm - see:
