Class Protos.ScryptParameters

  • All Implemented Interfaces:
    com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, Protos.ScryptParametersOrBuilder
    Enclosing class:
    Protos
    public static final class Protos.ScryptParameters
extends com.google.protobuf.GeneratedMessageLite<Protos.ScryptParameters,​Protos.ScryptParameters.Builder>
implements Protos.ScryptParametersOrBuilder
     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:
