Hat.sh: The Ultimate Guide to Encrypted File Sharing

Top 7 Tips for Safe File Sharing with Hat.sh

1. Use strong, unique passwords for links
   When creating an encrypted link, choose a long, random password (12+ characters with letters, numbers, and symbols). Don’t reuse passwords from other services.

2. Enable one-time access or set expirations
   Prefer links that self-destruct after one download or set a short expiration window to reduce exposure if a link is leaked.

3. Verify recipient identity out-of-band
   Send the decryption password using a different channel (e.g., SMS, phone call, or an encrypted messenger) than the link itself to prevent interception.

4. Avoid sharing sensitive metadata
   Don’t include names, account numbers, or other identifying details in filenames or accompanying messages. Rename files to neutral labels before uploading.

5. Limit file size and content scope
   Only upload what’s necessary. Split large archives if possible and avoid bundling unrelated sensitive files together.

6. Check the platform’s privacy practices
   Confirm that uploads are encrypted client-side and that the service doesn’t log identifiable metadata. Prefer services that delete files after download or expiration.

7. Keep local devices secure
   Ensure your computer and any recipient devices have up-to-date OS and antivirus, use full-disk encryption where possible, and lock screens when unattended.
