Syntax

public static int MakeDetachedSig(
   string outputFile,
   string hexDigest,
   string certList,
   string privateKey,
   HashAlgorithm hashAlg = HashAlgorithm.Sha1,
   Cms.SigDataOptions advOptions = Cms.SigDataOptions.Default 
)

Public Shared Function MakeDetachedSig (
   outputFile As String,
   hexDigest As String,
   certList As String,
   privateKey As String,
   Optional hashAlg As HashAlgorithm = HashAlgorithm.Sha1,
   Optional advOptions As Cms.SigDataOptions = Cms.SigDataOptions.Default 
) As Integer

Parameters

outputFile  String

name of output file to be created

hexDigest  String

string containing message digest in hex format

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.

hashAlg  HashAlgorithm  (Optional)

Message digest algorithm to be used in signature [default=SHA-1]

advOptions  Cms.SigDataOptions  (Optional)

Advanced option flags.
