What is secretshare.eu?
Encryption in the browser, decryption key in the URL fragment, one-time read and deletion after viewing.

Dear reader,
I’m Rémy Sainsard, and this is my first article about a tool I built called Secret Share.
The basic idea is simple: it lets you send a message or a short piece of text in a secure way. Stated like that, it’s vague — it’s not obvious what exactly is being “secured”.
So let me try to explain!
Encryption on your machine
Secret Share encrypts your message directly on your computer (in the browser). The text you type is not sent in plain form to our server. We only receive the already encrypted message — so it is impossible for us to know what you originally wrote. It also means it doesn’t travel over the network in a readable form.
What’s inside the URL
Once your message is encrypted, Secret Share gives you a URL. It contains two important parts:
- The reference — it lets us find the encrypted message in our database so we can deliver it to whoever opens the link.
- The decryption key — only you have it, via the generated URL: it is never stored on or sent to our servers. With that key, the person who opens the link can read the message you wanted to share.
After reading
Finally, once the message has been read using the URL you shared, the encrypted message in our database is permanently deleted. No one can read your message again.
