yhsm-yubikey-ksm --key-handles ... [options]

This is a small network server with a REST-like API that decodes YubiKey OTPs.

It can be used as a decryption backend (Key Storage Module) to a validation service such as the YubiCloud.

The AES keys of the YubiKeys must be present as AEAD files decryptable to the attached YubiHSM. Such AEADs can for example be created using yhsm-import-keys\|(1).

Note that this daemon is single threaded \(hy it will only handle a single request at once. A request timeout is therefor most important.
