wrap method on the other side of the context. The method will return the message supplied by the peer application to its wrap call, while at the same time verifying the embedded MIC for that message.The MessageProp object is instantiated by the application and is used by the underlying mechanism to return information to the caller such as the QOP, whether confidentiality was applied to the message, and other supplementary message state information.
Since some application-level protocols may wish to use tokens emitted by wrap to provide "secure framing", implementations should support the wrapping and unwrapping of zero-length messages.
@param inBuf a byte array containing the wrap token received frompeer. @param offset the offset where the token begins. @param len the length of the token @param msgProp upon return from the method, this object will containthe applied QOP, the privacy state of the message, and supplementary information stating if the token was a duplicate, old, out of sequence or arriving after a gap. @return a byte[] containing the message unwrapped from the inputtoken. @throws GSSException containing the following major error codes: {@link GSSException#DEFECTIVE_TOKEN GSSException.DEFECTIVE_TOKEN}, {@link GSSException#BAD_MIC GSSException.BAD_MIC}, {@link GSSException#CONTEXT_EXPIRED GSSException.CONTEXT_EXPIRED}, {@link GSSException#FAILURE GSSException.FAILURE}
