(How to set up Secure File Storage & Viewing)
STEP 1: The Setup 🛠️

Place the Vault element on your page (it can be invisible/1x1px). This loads the cryptographic engine.

STEP 2: Encrypting Files (Upload Flow) 🔒 Use this workflow when a user uploads a document/image.

Add a standard File Uploader element to your page.

Create a workflow (e.g., "Save" button).

Add the action: Vault - Encrypt File.

File URL: Dynamic link from the File Uploader.

Password: The user's secret key/password.

Add an event: Vault - Encryption Success.

Inside this event, create a new thing in your Database.

Save the Content: Save the state Vault A's encrypted_file_base64 into a Text field (or upload it as a file).

Save the Name: Save Vault A's original_file_name (e.g., "report.pdf") so you know the file type later.

STEP 3: Decrypting & Viewing Files (View Flow) 👁️ Use this workflow to safely view files without downloading them to the disk.

Create a workflow (e.g., "View Document" button).

Add the action: Vault - Decrypt File.

Encrypted File URL: The data you saved in Step 2. (Accepts both a URL or the raw Base64 string).

Password: The same secret key used to encrypt.

Displaying Images:

Set an Image element's source to Vault A's decrypted_file_url.

Downloading Files:

Set a Link element's destination to Vault A's decrypted_file_url and verify "Open in new tab" is checked.

Note: This URL is a secure Blob URL that lives only in the browser's RAM. It cannot be shared and expires when the page closes.

STEP 4: Encrypting Text/Data (Optional) 📝 For sensitive notes, API keys, or JSON.

Use the Vault - Encrypt Text action to secure text strings.

Save the encrypted_output string to your database.

Use Vault - Decrypt Text to read it back.

💡 Pro Tips:

Database Storage: Base64 strings are large. for small files (<5MB), a Text field is fine. For larger files, consider using a plugin to upload the Base64 string back to S3 as a .vault file.

Error Handling: Always use the Error event to alert the user if they entered the wrong password.

Zero Knowledge: Remind users that if they lose their password, the file is lost forever. There is no reset button.
