title: Is it possible to use 'ALG_HMAC_SHA1' method from 'Signature' class in javacard framework 2.2.1 version?
body: <p>I want to use ALG_HMAC_SHA1 method from javacard.security.Signature class. But my javacard framework version is 2.2.1 so Signature class does not include this method for this version. 
  it includes this method after 2.2.2. Is it possible to use this method without upgrading framework version? </p>
