Web28 apr. 2011 · An HMAC is a digest used to verify the authenticity of a message. Unlike, say an md5 signature, it's generated using a secret key known only to you and the receiving party so that it shouldn't be possible to forge by a third party. In order to generate one, you'll need to make use of some java.security classes. Try this:
