Trivia

In a kindergarten, children are meant to be cherished and cared for like young plants. The German word has survived to this day and has spread to many other languages. HashGarten borrows the idea: it is a garden, too, but one for hash algorithms.

Internals

• HashGarten is written entirely in Java and uses Swing.
• It uses Jacksum as a library and calls its API; it never runs the Jacksum command line tool.
• It uses FlatLaf for a modern look and feel.
• It accepts the same options as Jacksum, so it can be preconfigured from the command line.
• It stores its settings in $HOME/.HashGarten.properties.
