Values:

[.NET] [Pascal] [ActiveX] Description

kuDigitalSignature = SmallInt(1) kuDigitalSignature kuDigitalSignature = 1 Subject private key is used with a digital signature mechanism to support security services other than non-repudiation, certificate signing, or revocation information signing.

kuNonRepudiation = SmallInt(2) kuNonRepudiation kuNonRepudiation = 2 Subject public key is used to verify digital signatures used to provide a non-repudiation service which protects against the signing entity falsely denying some action, excluding certificate or CRL signing.

kuKeyEncipherment = SmallInt(4) kuKeyEncipherment kuKeyEncipherment = 4 Subject private key is used for key transport.

kuDataEncipherment = SmallInt(8) kuDataEncipherment kuDataEncipherment = 8 Subject public key is used for enciphering user data, other than cryptographic keys.

kuKeyAgreement = SmallInt(16) kuKeyAgreement kuKeyAgreement = 16 Subject public key is used for key agreement.

kuKeyCertSign = SmallInt(32) kuKeyCertSign kuKeyCertSign = 32 Subject private key is used for certificates signing.

kuCRLSign = SmallInt(64) kuCRLSign kuCRLSign = 64 Subject private key is used for revocation information signing (e.g., a CRL).

kuEncipherOnly = SmallInt(128) kuEncipherOnly kuEncipherOnly = 128 When the EncipherOnly property is set and the KeyAgreement is also set, the subject public key may be used only for enciphering data while performing key agreement.

kuDecipherOnly = SmallInt(256) kuDecipherOnly kuDecipherOnly = 256 When the DecipherOnly property is set and the keyAgreement is also set, the subject private key may be used only for deciphering data while performing key agreement.

Description

Use this property to specify key usages that certificate must have.

Note: KeyUsageOptions assigning differs for VCL and ActiveX and .NET versions. To enable several options in ActiveX and .NET use bitwise OR operation, for example "kuDigitalSignature | kuCRLSign | kuKeyAgreement".
