Basic Server Libraries

---

To integrate decryption and parsing of Yubikey One-Time Password (OTP) codes into your own server environment, you can use our free software libraries written in C and Java. To be useful, these packages needs to be combined with a database and server component. Note that most applications typically talk to a verification server, using our client libraries.
