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.NET]
Public Shared Function GetSigHashAlgorithm ( _
inputFile As String, _
certFile As String _
) As Integer
Parameters
- inputFile
- name of file containing CMS signed-data object
- certFile
- an (optional) X.509 certificate file to be used to identify the signer
Return Value
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)
