Examples of java.security.Signature.verify()

java.security.Signature.verify()
Verifies the passed-in signature.
A call to this method resets this signature object to the state it was in when previously initialized for verification via a call to initVerify(PublicKey). That is, the object is reset and available to verify another signature from the identity whose public key was specified in the call to initVerify. @param signature the signature bytes to be verified. @return true if the signature was verified, false if not. @exception SignatureException if this signature object is not initialized properly, the passed-in signature is improperly encoded or of the wrong type, if this signature algorithm is unable to process the input data provided, etc.
