SecureSling

Easily and securely share your files with client-side encryption.

SecureSling ensures your files are protected during upload and download with advanced encryption techniques.

Easy to Use

The intuitive interface makes file sharing simple and straightforward.

Secure E2E Encryption

Files are encrypted with AES-GCM using a 256-bit key to ensure data privacy and security. This state-of-the-art encryption standard provides robust protection for your files.

One-Time Downloads

Enable one-time downloads to ensure your files are accessed only once.

Client-Side Encryption

With this service, your files are encrypted and decrypted directly on your device. This means that only you and the recipient can access the content of the files. The server never has access to your unencrypted files, ensuring maximum privacy and security.

Here's how it works:

Before uploading, your files are encrypted using AES-GCM with a 256-bit key, a state-of-the-art encryption standard.
Only the encrypted version of your files is uploaded to the server.
When downloading, the encrypted files are decrypted on your device using the decryption key you provided.

This client-side encryption model guarantees that your data remains private and secure, as it is never exposed to the server in an unencrypted form. You can trust that your sensitive information is safe with SecureSling.
