Cms.GetSigHashAlgorithm Method

Find ID of message digest hash algorithm used to make signature.

Syntax

[C#]

public static int GetSigHashAlgorithm(
   string inputFile,
   string certFile 
)

[VB]

Public Shared Function GetSigHashAlgorithm (
   inputFile As String,
   certFile As String 
) As Integer

Parameters

inputFile String: name of file containing CMS signed-data object
certFile String: an (optional) X.509 certificate file to be used to identify the signer

Return Value

Int32
0=SHA-1, 1=MD5, 2=MD2, 3=SHA-256, 4=SHA-384, 5=SHA-512, 6=SHA-224; or a negative error code

Remarks

This method returns an integer ID number. Alternatively, use Cms.QuerySigData(inputFile, "digestAlgorithm") to get the name directly as a string, e.g. "sha1". See QuerySigData(String, String)
