What Is Encrypted File Sharing?
Encrypted file sharing means the file is transformed into ciphertext before it is sent and remains protected during the transfer. The recipient uses the shared link to obtain and decrypt the file in a compatible browser.
It is different from sending a normal email attachment or placing a file in a permanent shared drive. The security model, retention period, and link controls matter as much as the encryption algorithm.
How Looslee Protects A Transfer
- Encrypt: The current web app encrypts selected files in the browser using AES-256-GCM before upload.
- Upload: The service receives encrypted bytes and transfer metadata needed to deliver the file.
- Share: You share a temporary link or transfer code with the intended recipient.
- Expire: The transfer is designed for one successful download and a short sender-selected expiry window.
When Should You Use It?
- Sending a large document, photo set, archive, or video without creating an account.
- Sharing a temporary file that should not remain in a permanent collaboration folder.
- Moving a file between your phone and computer with a short-lived link or QR code.
Important Limits
Anyone who obtains the complete share link may be able to use the transfer, so share it through a channel you trust. Looslee is not a backup service, certified destruction system, or replacement for a managed enterprise data-loss-prevention program.
