javax.xml.crypto.dsig.spec.HMACParameterSpec
- All Implemented Interfaces:
- AlgorithmParameterSpec,- 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>
