Sign Method
Signs a buffer.
Object Oriented Interface
public function doSign($buffer, $detached);
Procedural Interface
secureblackbox_publickeycrypto_do_sign($res, $buffer, $detached);
Remarks
Use this method to sign a byte array and get the protected message in another byte array. Set the Detached parameter to false to create an enveloped/enveloping, rather than detached signature.Please note that certain signature algorithms/kinds only support detached signing.
Specify the signing key in Key property before commencing the signing.
Please note that the key assigned must have a private key part.
