What
Flashpaper is a secure web application designed for
confidential sharing.
When you add a secret, the app encrypts the data
entirely within the browser using JavaScript,
ensuring the server never sees or stores the
unencrypted content. Once encrypted, Flashpaper
generates a unique, one-time link that includes the
encryption key within the URL itself. This link can
then be shared with another person for secure access
to the data.
When the link is opened, the secret is decrypted in
the recipient's browser using the key in the URL.
After the link is accessed, it self-destructs,
preventing any further access. This method keeps all
sensitive information hidden from the server, with
encryption handled solely on the client side.
Wat
Using this Flashpaper app to share secrets should
feel risky! After all, you’re relying on someone
else’s code+server for sensitive encryption tasks.
Without inspecting the code yourself and hosting it
on a trusted server, you’d have to be a little bit
mad to fully trust that your data is genuinely
secure and private.
Consider building or hosting your own instance of
this Flashpaper application.
