public string SigningAlgorithm { get; set; }
Public Property SigningAlgorithm As String

Default Value



This property specifies the hash algorithm used to prepare the message digest for signature.

This property must contain either the name of the algorithm (such as "MD5" or "SHA1"), or an object id (OID) string representing the hash algorithm. Possible values are:

  • sha1
  • md5
  • sha-256 (default)
  • sha-384
  • sha-512
  • sha-224

When read, the value of the property always contains the OID of the algorithm, or an empty string if the algorithm is unknown.
