Cms.MakeSigData(String, String, String, String, Cms.SigAlg, Cms.SigDataOptions) Method

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

Syntax

public static int MakeSigData(
   string outputFile,
   string inputFile,
   string certList,
   string privateKey,
   Cms.SigAlg sigAlg,
   Cms.SigDataOptions advOptions = Cms.SigDataOptions.Default 
)

Public Shared Function MakeSigData (
   outputFile As String,
   inputFile As String,
   certList As String,
   privateKey As String,
   sigAlg As Cms.SigAlg,
   Optional advOptions As Cms.SigDataOptions = Cms.SigDataOptions.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  Cms.SigAlg

Signature algorithm.

advOptions  Cms.SigDataOptions  (Optional)

Advanced option flags.

Return Value

Example

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);
