Purpose
Run Base64, URL encoding, and SHA-256 hashing in the browser.
How it works
Base64 and URL encoding are reversible representations; SHA-256 is a one-way digest, not encryption or a password-storage algorithm.
Input
Enter text, numbers, a file, or a query target as required. Start with the page example to confirm the format, then replace it with your data.
Interpreting output
Confirm output format, units, and status, then compare with the input and target environment; successful formatting does not prove validity.
Limitations and privacy
This tool processes input locally in the browser and does not send it to the server.
