macOS Keychain Certificates

You can add and remove certificates provided by the Signum agent to the macOS keychain. This is required to be able to use keys with native tools like Codesign and Productsign.

Use the signum-util tool with the keychain command to add and remove certificates.

Private keys cannot be exported from the HSM.

Adding to Keychain

The signum-util keychain --add command adds all certificates to the keychain:

CODE

signum-util keychain --add

CODE

Certificate with alias [Signum-RSA-4096] and ID [21] was added successfully to the KeyChain

After adding to the keychain, the certificate(s) should be listed:

CODE

sc_auth identities

CODE

SmartCard: com.keyfactor.signum.token:21
Unpaired identities:
C08811A3E3E1CA52F4629433E700FA44B42EA701	Signum-RSA-4096

Removing from Keychain

To remove certificates from the keychain, run the following command:

CODE

signum-util keychain --clear

CODE

Signum certificates where successfully removed from the KeyChain

After removing from the keychain, the certificate(s) are removed and will not be available to the keychain.
