Public Key Usage Property Page

This property page displays the purposes that the public key can be used for. These usages are based on the PKIX Working Group Internet Draft, X.509 Certificate, and CRL profile. Some usages may not be available, depending on the product that Novell® Certificate Server ships with.

Digital Signature
A check mark in this check box indicates that the public key is used in verifying digital signatures that have purposes other than non-repudiation, certificate signature, and CRL signature.

Non-Repudiation
A check mark in this check box indicates that the public key is used in verifying digital signatures used to provide a non-repudiation service. This protects against the signing entity falsely denying some action, excluding certificate or CRL signing.

Key Encipherment
A check mark in this check box indicates that the public key is used for key encryption so that a key can be transmitted over the network--for example, when an RSA* key is to be used exclusively for key management.

Data Encipherment
A check mark in this check box indicates that the public key is used for encrypting user data, except for cryptographic keys.

Key Agreement
A check mark in this check box indicates that the public key is used for key agreement--for example, when a Diffie-Hellman key is to be used exclusively for key management.

Certificate Signing
A check mark in this check box indicates that the public key is used for verifying a signature on certificates.

CRL Signing
A check mark in this check box indicates that the public key is used for verifying a signature on a Certificate Revocation List (CRL).

Encipher Only
If this check box and the Key Agreement check box are checked, the public key can be used for encrypting data while performing key agreement. If the Key Agreement check box is not checked, this check box has no meaning.

Decipher Only
If this check box and the Key Agreement check box are checked, the public key can be used only for decrypting data while performing key agreement. If the Key Agreement check box is not checked, this check box has no meaning.
