The https://a-maugli.github.io/bip39toalgo/ is the Github web page for the repository https://github.com/a-maugli/bip39toalgo, forked from the original repository https://github.com/abmera/bip39toalgo
In the https://github.com/a-maugli/bip39toalgo repository the node app and the web app
was rebuilt from sources. This seemed the appropriate way, as bip39toalgo handles very sensitive data.
