As the author of SecureShare Vault (SSV), I designed this solution with one clear mission: to enable secure file and text sharing with zero-knowledge encryption. This means that no one — not even the server — can access your data. Everything is encrypted on the client-side, and decryption happens only in the recipient's browser with the correct key and optional master password.

You can explore the documentation at https://ssv.hlab.au/help.

Key Features

Client-side encryption Your message and files are encrypted before leaving your browser.
Zero-knowledge architecture The server never sees your plaintext content or passwords.
Optional password protection Add a master password for an additional layer of security.
Custom URLs Create human-friendly short links for easier sharing.
Expiration settings Define the maximum number of downloads and storage duration.
Automatic deletion Assets self-destruct after reaching download or time limits.

Creating a Secure Share

The process is simple and user-friendly.

Step 1: Enter Your Message and Files

You can enter an optional text message and upload multiple files. Both will be encrypted together.

Step 2: Add Security and Customization

  • Set a master password (optional).
  • Define a custom short URL for easy access.
  • Configure expiration settings — e.g., 3 downloads within 1 day.

Step 3: Generate Secure Link

Once created, you'll receive both a short URL and a full URL. Share either with your recipient.

Recipients will need the master password to decrypt if you enabled it.

Accessing Shared Content

When the recipient opens the link:

  1. If password-protected, they'll first enter the master password.

  2. After successful decryption (performed locally in their browser), the content is revealed:

    • The message
    • Downloadable files
    • Remaining download count and expiry date
    Decrypted content display with files and metadata
    Decrypted content

Use Cases

  • Secure business communications: Share confidential contracts, invoices, or sensitive project files.
  • Personal data sharing: Safely send IDs, passwords, or private documents.
  • Temporary access: Provide information that should expire after one-time or limited use.
  • Audit and compliance: Ensure content is automatically destroyed after intended use.

Why SecureShare Vault?

Unlike conventional file-sharing services, SecureShare Vault ensures absolute confidentiality by design:

  • The server only stores encrypted blobs.
  • Decryption happens only in the client's browser.
  • The master password is never transmitted.

This guarantees trustless security, making SecureShare Vault ideal for sensitive and regulated environments.
