Your files are encrypted before they leave your browser. The key never touches our servers. This demo uses the Web Crypto API — the same AES-256-GCM encryption CYFR Vault uses in production.
Choose any file from your computer. It will be encrypted entirely in your browser — nothing is uploaded to a server.
Generating encryption key...
Your file has been encrypted with AES-256-GCM. The encryption key was generated in your browser and never transmitted.
The encrypted file is stored for 1 hour. Share the link and encryption key with your recipient through a secure channel.
If you received an encrypted file and the key, you can decrypt it here.
