Route
/zip/encrypt
Open the workspace, protect the file, and download the result locally.
Why teams protect ZIP archives
People use this route when they need to encrypt ZIP files online and want a browser-based workflow instead of relying only on archive-level protection.
When Cryptvert is better than native protection
Archive passwords can be fine for ZIP-specific workflows, but Cryptvert is better when you want a consistent .vault handoff across archives and other file types with the same user experience.
Best for
- Project bundles delivered to vendors or clients
- Backups that need a separate password from the stored archive
- Operations handoffs where one ZIP contains many internal files
Not for
- Unzipping or inspecting the archive contents during encryption
- Replacing existing archive tooling for compression settings
- Multi-file uploads when you have not created the ZIP yet
Common use cases
- Wrap a release bundle before sending it externally
- Encrypt archived project files for long-term storage
- Protect vendor handoff packages that already ship as ZIPs
Mistakes to avoid
- Expecting Cryptvert to unpack or preview the archive
- Using a ZIP route for a single file that would be simpler on its own format page
- Reusing the same passphrase across multiple external handoffs
Quick checklist
- Confirm the source file is a .zip archive
- Generate a strong passphrase before processing
- Download the .vault result and store it safely
- Send the password over a different channel from the archive
Before you send
- Confirm that the selected ZIP archive is the one you want to protect.
- Keep the vault file and the passphrase in separate channels.
- Test one decrypt cycle first for important or time-sensitive handoffs.
Password reminders
- Store the passphrase somewhere secure before you send the vault.
- Avoid reusing passwords from other sensitive workflows.
- If you share the file with someone else, send the password separately.
What to expect after download
- The downloaded result will be a .vault package.
- The original file is wrapped, not converted into a native passworded document format.
- Review the filename after download so you know exactly what you are sending.
Visible FAQ
What does the ZIP encrypt route actually do?
Cryptvert wraps the original ZIP archive inside an encrypted .vault package in your browser. It does not apply a native ZIP password format to the file itself.
Does Cryptvert unpack or inspect the ZIP contents?
No. Cryptvert wraps the archive file itself, not the individual contents inside it.
Will I get the same ZIP archive back after decryption?
Yes. The decrypt route restores the original ZIP archive without changing its internal file structure.
Why use a vault around a ZIP file?
Teams often use this route when they want one consistent passphrase workflow across ZIP archives and non-archive file types.
