# Swap keys generator



[Cette page en français.](LISEZMOI.md)



Generator of reversible 256-byte blocks for encrypting data by exchanging values. Each byte in the final set is represented only once.



If you're developing under Delphi or Pascal in general, you can use these blocks with the TOlfCryptDecrypt.SwapCrypt and TOlfCryptDecrypt.SwapDecrypt functions in the [Olf.RTL.CryptDecrypt](https://github.com/DeveloppeurPascal/librairies/blob/master/src/Olf.RTL.CryptDecrypt.pas) unit.



This code repository contains a project developed in Object Pascal language under Delphi. You don't know what Delphi is and where to download it ? You'll learn more [on this web site](https://delphi-resources.developpeur-pascal.fr/).

## Source code installation



To download this code repository, we recommend using "git", but you can also download a ZIP file directly from [its GitHub repository](https://github.com/DeveloppeurPascal/Swap-Keys-Generator).



This project uses dependencies in the form of sub-modules. They will be absent from the ZIP file. You'll have to download them by hand.



* [DeveloppeurPascal/AboutDialog-Delphi-Component](https://github.com/DeveloppeurPascal/AboutDialog-Delphi-Component) must be installed in the ./lib-externes/AboutDialog-Delphi-Component subfolder.

* [DeveloppeurPascal/librairies](https://github.com/DeveloppeurPascal/librairies) must be installed in the ./lib-externes/librairies subfolder.



## Compatibility



As an [Embarcadero MVP](https://www.embarcadero.com/resources/partners/mvp-directory), I benefit from the latest versions of [Delphi](https://www.embarcadero.com/products/delphi) and [C++ Builder](https://www.embarcadero.com/products/cbuilder) in [RAD Studio](https://www.embarcadero.com/products/rad-studio) as soon as they are released. I therefore work with these versions.



Normally, my libraries and components should also run on at least the current version of [Delphi Community Edition](https://www.embarcadero.com/products/delphi/starter).



There's no guarantee of compatibility with earlier versions, even though I try to keep my code clean and avoid using too many of the new ways of writing in it (type inference, inline var and multiline strings).



If you detect any anomalies on earlier versions, please don't hesitate to [report them](https://github.com/DeveloppeurPascal/Swap-Keys-Generator/issues) so that I can test and try to correct or provide a workaround.
