CmsMakeSigData(String, String, String, String, CmsSigAlg, CmsSigDataOptions) Method

Create a CMS object of type SignedData from an input data file (advanced options including RSA-PSS).

Namespace: CryptoSysPKI
Assembly: diCrSysPKINet (in diCrSysPKINet.dll) Version: 23.0.0.30549 (23.1.0.0)

Syntax

public static int MakeSigData(
	string outputFile,
	string inputFile,
	string certList,
	string privateKey,
	CmsSigAlg sigAlg,
	CmsSigDataOptions advOptions = CmsSigDataOptions.Default
)

Public Shared Function MakeSigData ( 
	outputFile As String,
	inputFile As String,
	certList As String,
	privateKey As String,
	sigAlg As CmsSigAlg,
	Optional advOptions As CmsSigDataOptions = CmsSigDataOptions.Default
) As Integer

Parameters

outputFile String: name of output file to be created
inputFile String: name of file containing message data to be signed
certList String: filename of the signer's certificate and (optionally) a list of other certificates to be included in the output, separated by semi-colons (;) Alternatively specify a single PKCS#7 certificate chain file (.p7c/.p7b) containing the signer's certificate.
privateKey String: private key data for the sender
sigAlg CmsSigAlg: Signature algorithm.
advOptions CmsSigDataOptions (Optional): Advanced option flags. See CmsSigDataOptions.

Return Value

Int32
Zero if successful; otherwise it returns an error code

Example

Copy

StringBuilder sbPrivateKey = Rsa.ReadPrivateKey("AlicePrivRSASign.p8e", "password");
string fnameOutput = "BasicSignByAlice.bin";
string fnameInput = "excontent.txt";
string fnameCert = "AliceRSASignByCarl.cer";
int n = Cms.MakeSigData(fnameOutput, fnameInput, fnameCert, sbPrivateKey.ToString(), Cms.SigAlg.Default, 0);
