Class JcePBMac1CalculatorBuilder

java.lang.Object

org.bouncycastle.pkcs.jcajce.JcePBMac1CalculatorBuilder

public class JcePBMac1CalculatorBuilder
extends Object

A builder for RFC 8018 PBE based MAC calculators.

By default the class uses HMAC-SHA256 as the PRF, with an iteration count of 8192. The default salt length is the output size of the MAC being used.
