Instructions are in RED text and should be removed from your document by deleting the text with the span tags. This document is intended to serve as an example of what is required of an OWASP project wiki page. The text in red serves as instructions, while the text in black serves as an example. Text in black is expected to be replaced entirely with information specific to your OWASP project.

What is OTR ?

OTR4J stands for off-the-record for Java. end-to-end encryption (off-the-record) is a system of communication where only communicating users can read the messages, neither eavesdropper nor communication facilitator channels can read messages, OTR4J provides simple framework and prototype that helps developers to easily implement end-to-end encryption into Java application. Example applications are messaging, file transfer, secure information transfer

Why use otr4j ?

It provides high degree of privacy and security

How does it work ?

OTR4J uses hybrid cryptography system. It uses RSA and ECDH for key exchanges and AES encryption. Technical details of protocol is explained here


Example API

Bob sends message to Alice

OTRClient bobClient = OTRClient.get(config);
bobClint.login(BOB_USER_ID, "password");
bobClient.sendMessage("Hello Alice", ALICE_USER_ID);

Alice reads messages

OTRClient aliceClient = OTRClient.get(config);
aliceClient.login(ALICE_USER_ID, "password");
aliceClient.readMessages();

Description

This is where you need to add your more robust project description. A project description should outline the purpose of the project, how it is used, and the value it provides to application security. Ideally, project descriptions should be written in such a way that there is no question what value the project provides to the software security community. This section will be seen and used in various places within the Projects Portal. Poorly written project descriptions therefore detract from a project’s visibility, so project leaders should ensure that the description is meaningful.

The Code Project Template is simply a sample project that was developed for instructional purposes that can be used to create default project pages for a Code project. After copying this template to your new project, all you have to do is follow the instructions in red, replace the sample text with text suited for your project, and then delete the sections in red. Doing so should make it clearer to both consumers of this project, as well as OWASP reviewers who are trying to determine if the project can be promoted to the next category. The information requested is also intended to help Project Leaders think about the roadmap and feature priorities, and give guidance to the reviews as a result of that effort.

Creating a new set of project pages from scratch can be a challenging task. By providing a sample layout, with instructional text and examples, the OWASP Code Project Template makes it easier for Project Leaders to create effective security projects and hence helps promote security.

Licensing

A project must be licensed under a community friendly or open source license.  For more information on OWASP recommended licenses, please see OWASP Licenses.
