SEMANTIC ANALYSIS

The results of our semantic analysis are shown below using the website's language.

They are the main concepts covered by jwt.io.

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

Topics
JSON Web Token Confidence: 88% Arrow up

JSON Web Token (JWT) is a JSON-based open standard (RFC 7519) for creating access tokens that assert some number of claims.

For example, a server could generate a token that has the claim "logged in as admin" and provide that to a client.

The client could then use that token to prove that it is logged in as admin.

The tokens are signed by the server's key, so the client is able to verify that the token is legitimate.

The tokens are designed to be compact, URL-safe and usable especially in web browser single sign-on (SSO) context.

JWT claims can be typically used to pass identity of authenticated users between an identity provider and a service provider, or any other type of claims as required by business processes.

The tokens can also be authenticated and encrypted.

JSON Web Signature Confidence: 86% Arrow up

A JSON Web Signature (abbreviated JWS) is an IETF proposed standard for signing arbitrary JSON.

This is used as the basis for a variety of web based technologies including JSON Web Token.

Jehovah's Witnesses Confidence: 80% Arrow up

Jehovah's Witnesses is a millenarian restorationist Christian denomination with nontrinitarian beliefs distinct from mainstream Christianity.

The group reports a worldwide membership of more than 8.3 million adherents involved in evangelism, convention attendance figures of more than 17 million, and an annual Memorial attendance of more than 20 million.

Jehovah's Witnesses are directed by the Governing Body of Jehovah's Witnesses, a group of elders in Warwick, New York, which establishes all doctrines based on its interpretations of the Bible.

They prefer to use their own translation, the New World Translation of the Holy Scriptures, although their literature occasionally quotes and cites other Bible translations.

They believe that the destruction of the present world system at Armageddon is imminent, and that the establishment of God's kingdom over the earth is the only solution for all problems faced by humanity.

JWt (Java web toolkit) Confidence: 80% Arrow up

JWt (pronounced "jay-witty") is an open source widget-centric web application framework for the Java programming language developed by Emweb.

It has an API that uses established GUI application development patterns.

The programming model is component-based and event-driven, similar to Swing.

Digital signature Confidence: 77% Arrow up

A digital signature is a mathematical scheme for demonstrating the authenticity of digital messages or documents.

A valid digital signature gives a recipient reason to believe that the message was created by a known sender (authentication), that the sender cannot deny having sent the message (non-repudiation), and that the message was not altered in transit (integrity).
