Short description: One-Time Password (OTP) validation server for YubiKey tokens
First things first, you will need access to a server or computer running CentOS 8. This guide was written specifically with a server running CentOS 8 in mind, although it should also work on older, supported versions of the operating system.
Also, make sure you are running a regular, non-root user with sudo privileges configured on your server. When you have an account available, log in as your non-root user to begin.
There are several ways to install ykval-export on CentOS 8. You can use (links are clickable):
In the following sections, we will describe each method in detail. You can choose one of them or refer to the recommended one.
First, update dnf packages database with
dnf by running the next command:
sudo dnf makecache --refresh
After updating database,
You can install ykval-export using
dnf by running the
sudo dnf -y install yubikey-val
Because ykval-export is available in CentOS 8’s default
it is possible to install it from these repositories using the
To begin, update local packages database with

dnf update yubikey-val
To uninstall only the
ykval-export package you can execute
sudo dnf remove yubikey-val
YubiKeys are USB tokens that act like keyboards and generate one-time passwords. This package contains a server written in PHP for use with Apache to validate YubiKey OTPs. The architecture is that a set of validation servers manage the token counters and respond to OTP requests from clients, and utilize a set of back-end YubiKey Key Storage Module (KSM) servers to perform the actual AES key decryption. The protocols are openly published. There are two implementations of the KSM available: yubikey-ksm (PHP, secrets on disk in database) and yhsm-yubikey-ksm (Python, for use with secrets protected by the YubiHSM hardware). Sometimes the KSM runs on another server than the validation server, but it is possible to run both on the same machine. After installing and configuring this package you will have a YubiKey validation server up and running via Apache.
You now have a full guide on how to install
yum package managers.
Also, we showed how to update manually as a single package and different ways to uninstall
