Frequently Asked Questions
Can I add a custom password to my shared file?
The 6-digit key serves as the password. It's automatically generated and cryptographically tied to the encryption. You share this key only with your intended recipient.
What happens if someone guesses the 6-digit key?
Rate limiting blocks brute-force attempts. With 1,000,000 possible combinations and rate limiting, guessing is not feasible.
Is files-share.com suitable for sharing confidential documents?
Yes — AES-256-GCM browser-side encryption means the server never sees your file. It's suitable for confidential documents, legal files, and personal data.
