public enum X509CertificatePropertyType
  Member nameValueDescription
None0 No property is identified.
Handle1 The handle of the private key associated with the certificate.
ProviderInfo2 Information about a CSP key container or a Cryptography API: Next Generation (CNG) key.
SHA1Hash3 SHA-1 hash value of the certificate
MD5Hash4 MD5 hash value of the certificate
DefaultHash3 Hash of the certificate created by using the default hashing algorithm. The default algorithm is currently SHA-1.
KeyContext5 Information necessary to retrieve a key, including the CSP or key service provider (KSP) handle and a value that indicates whether the key is used for signing or encryption.
KeySpec6 Value that identifies whether the key is used for signing or for encryption and whether the key is associated with a CNG Key Storage Provider.
