Stellar Secret Just Got a Major Upgrade — Now With Encrypted File Sharing
-
Stellar Security
Share:
We’re excited to announce a powerful new feature on Stellar Secret: you can now attach files to your secret messages — and just like your messages, these files are fully encrypted and viewable only once by the receiver.
🔒 One-Time, One-Viewer, Fully Encrypted
Here’s how it works:
When you send a message, you can now attach a file (up to 15 MB).
Both the message and the file are encrypted end-to-end.
The receiver can view the message and download the file once — after that, both are gone forever.
Even we can’t see what you share. No logs, no backups, no surveillance.
This is all made possible by the architecture behind Stellar Secret — which is, and always will be, open-source. Anyone can audit the code to verify that your data stays yours.
📁 File Sharing Starts Now
Today’s update supports files up to 15 MB in size. We know that’s just the beginning — and we’re already working on expanding this limit. This is the first step toward even richer, more secure forms of communication.
🌐 Check the Code
We believe in transparency. That’s why all of Stellar Secret’s code is available publicly:
Go ahead and poke around. Fork it, contribute, or just verify for yourself that everything is encrypted and private.
We’re not stopping here. More updates are on the way — but in the meantime, go try the new feature and send a secret (or a file) today: stellarsecret.io
