Configuring CA with Random Serial Numbers v3

Overview

This page describes the process to switch the ID generators in an existing CA from the legacy Sequential Serial Numbers or Random Serial Numbers v1 to Random Serial Numbers v3.

Warning

Switching back from Random Serial Numbers v3 to the legacy Sequential Serial Numbers or Random Serial Numbers v1 is not supported.

Configuration Process

Stopping PKI Server

First, stop PKI server:

$ pki-server stop --wait

Configuring Certificate Request ID Generator

Disable the legacy ID generator for certificate requests:

$ pki-server ca-config-unset dbs.beginRequestNumber
$ pki-server ca-config-unset dbs.endRequestNumber
$ pki-server ca-config-unset dbs.requestIncrement
$ pki-server ca-config-unset dbs.requestLowWaterMark
$ pki-server ca-config-unset dbs.requestCloneTransferNumber
$ pki-server ca-config-unset dbs.requestRangeDN

Enable the RSNv3 ID generator for certificate requests:

$ pki-server ca-config-set dbs.request.id.generator random
$ pki-server ca-config-set dbs.request.id.length 128

Configuring Certificate ID Generator

Disable the legacy ID generator for certificates:

$ pki-server ca-config-unset dbs.beginSerialNumber
$ pki-server ca-config-unset dbs.endSerialNumber
$ pki-server ca-config-unset dbs.serialIncrement
$ pki-server ca-config-unset dbs.serialLowWaterMark
$ pki-server ca-config-unset dbs.serialCloneTransferNumber
$ pki-server ca-config-unset dbs.serialRangeDN
$ pki-server ca-config-unset dbs.enableRandomSerialNumbers
$ pki-server ca-config-unset dbs.randomSerialNumberCounter

Enable the RSNv3 ID generator for certificates:

$ pki-server ca-config-set dbs.cert.id.generator random
$ pki-server ca-config-set dbs.cert.id.length 128

Restarting PKI Server

Finally, restart PKI server:

$ pki-server start --wait
