This repository will slowly get more and more cryptography code samples written in Java. Methods are related to Cryptography android application cipher method collection. Point of this repository is that users can find everything in one place, modify code, play with these methods in any way they want and this way learn how ciphers worked in the past and how they work these days. In short words this repository is meant to be educational.

- Download and install eclipse: https://www.eclipse.org/downloads/
- Download project source code by either cloning it with Git or by
Clone or downloadmenuDownload ZIPoption. - Open project in Eclipse
File-Open projects from File System... - Navigate to
/src-cryptography-Ciphers.javaand start play with it. Rest of the folder structure has method specific code and tests files for running automated tests.
I warmly recommend watching basic Eclipse tutorials if you are new to the topic.

</path>Some ciphers or parts of ciphers originate from web sites, tutorials, repositories or other sources. There's unfortunately no links to original references.
Please, write tests if you make something new.
Open issue or make new branch and create pull request when problem is fixed.
You are free to optimize code, make new branch and create pull request when ready.
