A link container bundles several download links under a single, short address. The target links are stored server-side encrypted and only delivered to the visitor after the access check is passed – ideal for sharing collections securely and neatly.

Every container can be secured with a password, a captcha and geo/IP rules. The target links are stored encrypted and never served in plain text before a visitor passes the access protection. This keeps your sources hidden from crawlers, bots and prying eyes.

The target links are stored in the database encrypted with AES-256-GCM on the server and are never served in plain text while the access protection has not been passed. This is encryption at rest, not true end-to-end encryption: the key lives on the server so that Zaulto can, for example, run the automatic online check on the links. What is encrypted are the target links themselves; a container's title and description are stored in plain text – so don't put confidential information there.

Three: a simple arithmetic challenge, an invisible proof-of-work (compute-based, no clicks) and a custom question with a stored answer. The proof-of-work offers the strongest protection against automated bots.

Yes. Zaulto generates DLC container files and Click'n'Load links that JDownloader processes directly – a single click adds all links to the download manager at once. The handover only happens after the access check has been passed.

Zaulto generates DLC files and Click'n'Load links for download managers such as JDownloader, which handle this container format directly. Internet Download Manager (IDM) does not support Click'n'Load or DLC. However, after unlocking you can copy the links contained in the container manually and paste them into IDM.

DLC, CCF and RSDF are encrypted link container formats that bundle several download links together and hide them from prying eyes. JDownloader can read all three formats. Zaulto exports your containers in the widely used DLC format and additionally offers Click'n'Load.

Yes. You can store several mirror sources for a file. Zaulto checks the links regularly and automatically switches to a working mirror if one goes down (failover), so downloads stay reliable.
Yes. Multi-part collections – such as RAR archives split into several parts – can be bundled as a link list in a single container. After unlocking, visitors get all parts at once, ideal for JDownloader.
Yes. Zaulto checks the status of the stored links automatically and marks whether a file is online or offline. Combined with mirror links, it switches to a working source if one fails.

Create a container, add your download links and secure it with a password, captcha or geo/IP rules. You then share only the short container address (optionally as a QR code) – the actual links stay encrypted until a visitor passes the access protection.

Creating and sharing containers is free. You only need a free account to create a container.
Yes. You need a free account to create a container. With an account you can also manage your containers later, view statistics and organize them in folders.
You can set a password for a container. Visitors must enter it before the links are released. The password is not stored in plain text, only as a secure hash (argon2id) for verification. It acts as an access key – the actual link encryption runs independently on the server.

With geo and IP rules you can restrict access to certain countries or block individual IP ranges. Requests that don't match are denied access to the links.

In stealth mode the actual container page is hidden behind an inconspicuous intermediate page. The real content is only revealed after the access check is passed – useful against automated preview and crawler bots.

AutoProtect automatically masks embedded containers and places an intermediate page in front of them so links can't be read directly by bots. The settings can be adjusted per account.

Yes. You can set an expiry date and limit the number of permitted accesses. Once expired or the limit is reached, the container is no longer accessible.

Yes. With an account you can group several containers into folders and share a folder via a single link. This keeps larger collections tidy.
The dashboard shows an access overview of the last 7 days: number of views, rough geographic distribution and the timeline. Zaulto builds no personal user profiles and sets no advertising trackers or third-party cookies. Technical access data is processed solely for statistics, protection rules (geo/IP, rate limit) and abuse prevention.
Containers are always tied to an account. In your dashboard you can deactivate any of your own containers any time with a single click – it is then immediately no longer accessible and disappears from the public directory. The associated links are no longer reachable afterwards.
The captcha challenges are HMAC-signed, single-use and verified server-side in constant time. After unlocking, the visitor receives a short-lived access token, so the download endpoints cannot be bypassed directly.

Yes. Creating, sharing, unlocking and the dashboard are fully optimized for mobile devices. Shared links can also be displayed as a QR code.
Containers with an expiry date, an auto-delete date or a reached access limit are automatically deactivated and are no longer accessible afterwards. A background process checks this continuously (every few minutes), so expired content disappears promptly – you don't have to do anything manually.

Each container can hold up to 40 links, plus optionally up to 20 mirror groups (mirror sets) with up to 200 links each. Title and description are length-limited. The number of containers per account is not rigidly capped; fair use applies. Per container you can also set your own rate limits, expiry dates and access caps.
Zaulto runs as a modern single-page application. JavaScript is needed to create containers, handle the access protection (captcha or proof-of-work), release links after a passed check, and provide features such as Click'n'Load and the dashboard. Without JavaScript enabled, containers can therefore neither be created nor unlocked.
Zaulto is a neutral technical service and does not host any files or target content itself – Zaulto is not a file host, it only protects and bundles links. The creator of a container is solely responsible for the linked content. Unlawful content can be reported and affected containers are blocked. Details are in the disclaimer.
You can report specific legal infringements via the contact form. Once we become aware, we remove affected containers without undue delay. Please provide the container address and a short justification.
