That took 2 seconds. Now do it for real.

Privacy Act Compliant

Every unencrypted email is a breach waiting to happen.

Your receptionist emails patient records as PDF attachments. Every one sits in cleartext on mail servers. ObsidianVault encrypts files in the browser before they leave. The server never sees your data.

Protect your next file

No account. No sign-up. 30 seconds.

Three steps. Zero trust required.

Drop your file

Drag and drop or click to select. Any file type, up to 200MB.

It encrypts locally

AES-256-GCM encryption happens in your browser. A random key is generated. Only ciphertext is uploaded.

Share the link

The decryption key lives in the URL fragment (#). Never sent to our server. Only the link holder can decrypt.

What does the recipient see?

They click the link. The file decrypts in their browser. No account. No app. No extra steps. They just get the file.

What if...

Our server is seized by law enforcement?

They get ciphertext. Random bytes. Mathematically indistinguishable from noise without the key. We don't have the key. It never touches our server.

We get hacked?

The attacker gets encrypted blobs and an audit log. No plaintext. No keys. The encryption key exists only in the URL you shared and in your browser's memory during the operation.

You subpoena us?

We'll comply fully. You'll receive ciphertext and a hash-chained audit trail proving when files were uploaded and downloaded. You will not receive plaintext, because we never had it.

A Melbourne medical practice needed to send patient records to a specialist. The files were too large to email. They split them across five unencrypted messages. Every one was a Privacy Act breach. With ObsidianVault, the receptionist dropped the files into a link. Encrypted in her browser. Delivered in 30 seconds. Zero training.
