The SHA Generator tool shown here is built for learners, researchers, and professionals who need a flexible and interactive way to test secure hash algorithms. Whether you're comparing SHA-1 against SHA-256, exploring SHA-3 variants, or just demonstrating how salts affect hashes, this tool provides a fast, clean interface for experimentation. You can input a central message and optionally apply a pre-salt and/or post-salt string to add variability to the output. You also have control over the output format—uppercase or lowercase—and can choose from various SHA algorithms, including SHA-0, SHA-1, SHA-2, and SHA-3 families.
Once configured, clicking "Submit" will send your input to the server, where the hash is computed in-memory using your selected settings. The result is returned instantly, without storing any data you enter. This makes the tool especially useful in academic environments, secure development testing, or cybersecurity training, where transparency and reproducibility are key.
As with all cryptographic tools on 2radical.dev, no inputs are stored, logged, or tracked. That said, we strongly advise not to use production data, real passwords, or private values within this tool. It is designed to be a trusted sandbox for hashing experimentation, education, and validation—ideal for hashing practice, but not meant for handling real-world sensitive content.
