Class HMACParameterSpec

java.lang.Object
javax.xml.crypto.dsig.spec.HMACParameterSpec
All Implemented Interfaces:
AlgorithmParameterSpec, SignatureMethodParameterSpec
public final class HMACParameterSpec extends Object implements SignatureMethodParameterSpec
Parameters for the XML Signature HMAC Algorithm. The parameters include an optional output length which specifies the MAC truncation length in bits. The resulting HMAC will be truncated to the specified number of bits. If the parameter is not specified, then this implies that all the bits of the hash are to be output. The XML Schema Definition of the HMACOutputLength element is defined as: 
<element name="HMACOutputLength" minOccurs="0" type="ds:HMACOutputLengthType"/>
<simpleType name="HMACOutputLengthType">
  <restriction base="integer"/>
</simpleType>
