About these security & encoding tools
Hashing, encoding and password utilities that run locally using the Web Crypto API. Nothing you type is transmitted, logged or stored — check the network tab and see for yourself.
All 100 tools here are free and open immediately — there is no registration step, no credit card and no daily allowance to run out of. Most of them do their work in your browser, which means the page keeps working on a slow connection and your input is never sent to a server.
