OidGroup Enumeration

.NET Framework 4.5

Identifies Windows cryptographic object identifier (OID) groups.

Namespace: System.Security.Cryptography
Assembly: System (in System.dll)

public enum OidGroup

	Member name	Description
	All	All the groups.
	Attribute	The Windows group that is represented by CRYPT_RDN_ATTR_OID_GROUP_ID.
	EncryptionAlgorithm	The Windows group that is represented by CRYPT_ENCRYPT_ALG_OID_GROUP_ID.
	EnhancedKeyUsage	The Windows group that is represented by CRYPT_ENHKEY_USAGE_OID_GROUP_ID.
	ExtensionOrAttribute	The Windows group that is represented by CRYPT_EXT_OR_ATTR_OID_GROUP_ID.
	HashAlgorithm	The Windows group that is represented by CRYPT_HASH_ALG_OID_GROUP_ID.
	KeyDerivationFunction	The Windows group that is represented by CRYPT_KDF_OID_GROUP_ID.
	Policy	The Windows group that is represented by CRYPT_POLICY_OID_GROUP_ID.
	PublicKeyAlgorithm	The Windows group that is represented by CRYPT_PUBKEY_ALG_OID_GROUP_ID.
	SignatureAlgorithm	The Windows group that is represented by CRYPT_SIGN_ALG_OID_GROUP_ID.
	Template	The Windows group that is represented by CRYPT_TEMPLATE_OID_GROUP_ID.

This enumeration is used by the FromOidValue method.
