About This Website

This Link Will Self Destruct (TLWSD) is a free public temporary URL service. Our mission is to provide the internet with a fast, friendly, private, and secure means to exchange hyperlinks without leaving a digital paper trail.

This service is designed for exchanging links over an untrusted medium (such as Facebook, internet forums, or IRC) without passive attackers (people with access to your conversation logs at a later date) being able to know what link you sent.

In the event of a successful exchange, this service does not obscure the destination URL from the intended recipient.

How To Use This Website

First, you need to have a URL you want to distribute to a limited number of end users. (For example, a Cryptocat chatroom.) Then head over to the TLWDS homepage and provide your hyperlink. Fill in the number of times you wish this link to be usable before it expires (a link's "life"). You may also select an expiration time (default: 30 days) so your information doesn't sit on the server forever. Select the level of security you want, then press the "Create Link" and you will receive an SDH — a Self-Destroying Hyperlink.

Security Levels:
  • Compact: Short URL. Ideal for sending over SMS and Twitter. Password recommended.
      Equivalent URL security: 24 bits
      (If multiple hash collisions are detected, security is upgraded to 32 and then 40 bits)
  • Medium: Standard level of brute-force resistance to your Self-Destroying Hyperlinks.
      Equivalent URL security: 48 bits
  • Secure: Long URL. Nearly impervious to brute-force attacks.
      Equivalent URL security: 160 bits

When someone accesses your SDH, the server will take 1 point away from the life of the hyperlink. When its life reaches 0, the file containing the hyperlink information will be shredded (learn more) from our server.

(Optional): You may also supply a password to your SDH. When users load the SDH in their web browser, they will be asked for the same password before they can continue to the destination URL. Supplying a password encrypts your destination URL.

If a brute force succeeds and an attacker arrives at your SDH, they will either arrive at your destination URL or be prompted for a password. That is why we strongly recommend passwords for compact URLs. If an attacker can find the door, they will be slowed down if it turns out to be locked.

Privacy Considerations

The use of this service does not guarantee privacy. It is always best to assume that any information sent can and will be intercepted. Any data sent to the server can be seen by the server, even if it isn't stored by design. This includes information such as your IP address, so it is highly recommended that you access our service through Tor.
