    Java JWT

    Java JWT

    Java implementation of JSON Web Token (JWT)

    A Java implementation of JSON Web Token (JWT) - RFC 7519. This library requires Java 8 or higher. The last version that supported Java 7 was 3.11.0. The library implements JWT Verification and Signing using several algorithms. The Algorithm defines how a token is signed and verified. It can be instantiated with the raw value of the secret in the case of HMAC algorithms, or the key pairs or KeyProvider in the case of RSA and ECDSA algorithms. Once created, the instance is reusable for token signing and verification operations. When using RSA or ECDSA algorithms and you just need to sign JWTs you can avoid specifying a Public Key by passing a null value. The same can be done with the Private Key when you just need to verify JWTs.

    Nomulus

    Nomulus

    Top-level domain name registry service on Google Cloud Platform

    Nomulus is a production-grade, open-source domain registry platform used to operate top-level domains (TLDs). It implements the core registry protocols—EPP for registrar interactions, WHOIS/RDAP for public data access—and manages the lifecycle of domain objects, hosts, and contacts. The system is built to scale and to enforce policy: pricing rules, reserved names, premium tiers, grace periods, and automated renewals are modeled explicitly. It integrates with DNS provisioning, data escrow, and billing so you can run a compliant registry end-to-end rather than stitching together separate services. Operators get admin tools for reporting, manual adjustments, and policy configuration, while registrars interact through standards-compliant channels. Nomulus treats registries as serious infrastructure: audited flows, durable storage, and clear extension points for custom policies and TLD-specific behavior.

    Java library for access to Moodle's web services via the REST protocol (09/11/2013) Development of this project has been resurrected and the current code may be downloaded from https://github.com/bantonia/MoodleRest A compiled .jar will be available here once the code has been finalized. (30/03/2012 A newer version (V0.1.5) to work with Moodle 2.2 has been uploaded. Although still requires more documentation (better than it was) etc... Calls to create and update users now provides facilities to add preferences and customfields. Removed the batch calling of the web services (not needed as all calls are via POST and not GET), code is still there but commented out. V0.1.4 was removed, too many bugs! Previous versions using the Moodle 2.1 webservice calls are still here. Code for the next release which is under development can be downloaded from: https://github.com/bantonia/MoodleRest Note: The software is supplied as is under the GNU version 2.0 License.
