Examples of java.security.Signature.sign()

java.security.Signature.sign()
Returns the signature bytes of all the data updated. The format of the signature depends on the underlying signature scheme.
A call to this method resets this signature object to the state it was in when previously initialized for signing via a call to initSign(PrivateKey). That is, the object is reset and available to generate another signature from the same signer, if desired, via new calls to update and sign. @return the signature bytes of the signing operation's result. @exception SignatureException if this signature object is notinitialized properly or if this signature algorithm is unable to process the input data provided.
