History for this tool
The most recent data you entered in this tool, stored only in this browser.
Save what you type here, in this browser? Your work would go into this browser's local storage, so a refresh or a trip to another tool does not wipe it. You also get a short list of previous entries under the form, each one restorable with a click. Nothing is ever uploaded, and there is no account.
Being straight about the trade-off: anything kept there can be read by anyone who can use this browser profile, and by any script that later runs on this site. A tool page can hold a private key, a password or a signed token. Saving is convenient; it is not private.

About this tool
Hide part of a string while leaving enough of it visible to recognise — the usual way to show a card number, an API key or an email address in a log, a ticket or a screenshot without exposing the whole value.Questions
- Is this a security measure?
- No. It is a presentation aid. The original value is still wherever you copied it from, and masking is not the same thing as redaction.
