The ikecert command manipulates the local system's public key databases. You use this command when the ike/config file requires public key certificates. Because IKE uses these databases to authenticate the Phase 1 exchange, the databases must be populated before activating the in.iked daemon. Three subcommands handle each of the three databases: certlocal, certdb, and certrldb.
The ikecert command also handles key storage. Keys can be stored on disk, on an attached Sun Crypto Accelerator 6000 board, or in a softtoken keystore. The softtoken keystore is available when the metaslot in the Cryptographic Framework is used to communicate with the hardware device. The ikecert command uses the PKCS #11 library to locate key storage.
The tokens argument lists the token IDs that are available. Token IDs enable the ikecert certlocal and ikecert certdb commands to generate public key certificates and certificate requests. The certificates and certificate requests can also be stored by the Cryptographic Framework in the softtoken keystore, or on an attached Sun Crypto Accelerator 6000 board. The ikecert command uses the PKCS #11 library to locate certificate storage.
The certlocal subcommand manages the private key database. Options to this subcommand enable you to add, view, and remove private keys. This subcommand also creates either a self-signed certificate or a certificate request. The -ks option creates a self-signed certificate. The -kc option creates a certificate request. Keys are stored on the system in the /etc/inet/secret/ike.privatekeys directory, or on attached hardware with the -T option.
When you create a private key, the options to the ikecert certlocal command must have related entries in the ike/config file. The correspondences between ikecert options and ike/config entries are shown in the following table.
Table 19-1 Correspondences Between ikecert Options and ike/config Entries
If you issue a certificate request with the ikecert certlocal -kc command, you send the output of the command to a PKI organization or to a certificate authority (CA). If your company runs its own PKI, you send the output to your PKI administrator. The PKI organization, the CA, or your PKI administrator then creates certificates. The certificates that the PKI or CA returns to you are input to the certdb subcommand. The certificate revocation list (CRL) that the PKI returns to you is input for the certrldb subcommand.
The certdb subcommand manages the public key database. Options to this subcommand enable you to add, view, and remove certificates and public keys. The command accepts, as input, certificates that were generated by the ikecert certlocal -ks command on a remote system. For the procedure, see How to Configure IKE With Self-Signed Public Key Certificates. This command also accepts the certificate that you receive from a PKI or CA as input. For the procedure, see How to Configure IKE With Certificates Signed by a CA.
The certrldb subcommand manages the certificate revocation list (CRL) database, /etc/inet/ike/crls. The CRL database maintains the revocation lists for public keys. Certificates that are no longer valid are on this list. When PKIs provide you with a CRL, you can install the CRL in the CRL database with the ikecert certrldb command. For the procedure, see How to Handle a Certificate Revocation List.
The /etc/inet/ike/publickeys directory contains the public part of a public-private key pair and its certificate in files, or slots. The directory is protected at 0755. The ikecert certdb command populates the directory. The -T option stores the keys on the Sun Crypto Accelerator 6000 board rather than in the publickeys directory.
The slots contain, in encoded form, the X.509 distinguished name of a certificate that was generated on another system. If you are using self-signed certificates, you use the certificate that you receive from the administrator of the remote system as input to the command. If you are using certificates from a CA, you install two signed certificates from the CA into this database. You install a certificate that is based on the certificate signing request that you sent to the CA. You also install a certificate of the CA.
The /etc/inet/secret/ike.privatekeys directory holds private key files that are part of a public-private key pair. The directory is protected at 0700. The ikecert certlocal command populates the ike.privatekeys directory. Private keys are not effective until their public key counterparts, self-signed certificates or CAs, are installed. The public key counterparts are stored in the /etc/inet/ike/publickeys directory or on supported hardware.
The /etc/inet/ike/crls directory contains certificate revocation list (CRL) files. Each file corresponds to a public certificate file in the /etc/inet/ike/publickeys directory. PKI organizations provide the CRLs for their certificates. You can use the ikecert certrldb command to populate the database.
