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

Namespace: CryptoSysPKI
Assembly: diCrSysPKINet (in diCrSysPKINet.dll) Version: 23.0.0.30549 (23.1.0.0)
Syntax
Copy
public static int GetSigHashAlgorithm(
	string inputFile,
	string certFile
)

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)
