[FlagsAttribute]
public enum X509KeyUsageFlags

Members

Member name	Value	Description
None	0	No limitations for the key usage are set.
EncipherOnly	1	The key may only be used for enciphering data during key agreement.
CrlSign	2	The key may be used for verifying signatures on certificate revocation lists (CRLs).
KeyCertSign	4	The key may be used for verifying signatures on certificates.
KeyAgreement	8	The key is meant to be used for key agreement.
DataEncipherment	16	The key may be used for data encipherment.
KeyEncipherment	32	The key is meant to be used for key encipherment.
NonRepudiation	64	The key may be used to verify digital signatures used to provide a non-repudiation service.
DigitalSignature	128	The key may be used for digitally signing data.
DecipherOnly	32,768	The key may only be used for deciphering data during key agreement.

Remarks

The X.509 Key Usage Flags can be used to determine what operations a certificate can be used for.

Tip
A value of None indicates that there are no restrictions on the use of the X509Certificate.
