CkCmsSigParams() public method

Initializes a new instance of the CkCmsSigParams class.

public CkCmsSigParams ( ObjectHandle certificateHandle, ulong signingMechanism, ulong digestMechanism, string contentType, byte requestedAttributes, byte requiredAttributes ) : System
certificateHandle	ObjectHandle	Object handle for a certificate associated with the signing key
signingMechanism	ulong	Mechanism to use when signing a constructed CMS SignedAttributes value
digestMechanism	ulong	Mechanism to use when digesting the data
contentType	string	String indicating complete MIME Content-type of message to be signed or null if the message is a MIME object
requestedAttributes	byte	DER-encoded list of CMS Attributes the caller requests to be included in the signed attributes
requiredAttributes	byte	DER-encoded list of CMS Attributes (with accompanying values) required to be included in the resulting signed attributes
return	System
