YubiCloud Connector Libraries

Yubico has declared end-of-life for the YubiKey Validation Server (YK-VAL) and YubiKey Key Storage Module (YK-KSM). These have been moved to YubicoLabs as a reference architecture. See article, YK-VAL, YK-KSM and YubiHSM 1 End-of-Life.

These libraries help with connecting to the YubiCloud for Yubico OTP validation from a number of different programming languages. Learn how to use a connector library here.

Third party implementations can be discovered on GitHub for example.
