Security that is useful in everyday sharing.
Email attachments are awkward for large files, and permanent cloud folders can be more access than a recipient needs. PsiDrive creates a temporary encrypted transfer for a specific sharing moment.
The transfer key is placed after the # in the link. Browsers do not send that fragment in the normal server request.
Guest transfers normally expire after 24 hours, with an optional delete-after-first-download setting.
How to send a secure file.
Choose a file in the browser. Guest transfers can use up to 1 GB per rolling 24 hours.
Your browser encrypts the filename and content, then uploads encrypted chunks.
Copy the generated link or show its QR code. Add an optional password through a separate channel.
