About this tool
Hash text with your browser’s built-in Web Crypto engine, as hex or Base64, line by line if you wish.
Like every tool on YantraStack, it is free with no accounts, limits or watermarks, and it works offline once the page has loaded. See how to verify that nothing is uploaded.
Questions
Why no MD5?
Browsers do not provide MD5 and it is broken for security use. Use SHA-256 or better.
Guides
How local-first browser tools work: PDFs, images and workers
A developer’s look at how tools like YantraStack process PDFs and images entirely client-side, using standard browser APIs, Web Workers and canvas.
How to generate a random password that websites will accept
Fix "password rejected" problems: set length, character types, start-with-a-letter and excluded characters, then generate several options.
How to generate a SHA-256 hash (and HMAC) of any text
Create SHA-256, SHA-512, SHA-384 or SHA-1 hashes, add a secret key for HMAC, and learn why hashing is not password storage.
