Private.sh Privacy Search Engine first look

[harlan4096]

Private.sh is a new search engine that was officially unveiled in November 2019. The search engine is maintained by Private Internet Access, a provider of VPN solutions and other tools, and Gigablast, a company that maintains an index of Internet pages.

Private.sh promises better privacy than other search solutions by encrypting searches on the user's system and by using secure proxies to hide user IP addresses.

The search term is encrypted automatically when users type search terms into the search field on the private.sh website and hit the search button. The request is then tunneled through a secure proxy maintained by Private Internet Access and submitted to Gigablast.

There, it is processed, encrypted using a temporary key, and send back the same way it came.

The announcement of the new service on the Private Internet Access website provides additional information on how this works:

When you enter a search term into Private.sh, the search term gets encrypted on the client side (on your computer or device) using GigaBlast’s public key, which only they can decrypt. In effect, this ensures that Private.sh never sees the search term.

After the search term is encrypted, it is passed to the GigaBlast search engine through a Private.sh proxy so GigaBlast doesn’t see your IP address, browser fingerprints, or anything that would allow for your privacy to be broken or a user profile to be created. This means that neither Private.sh or GigaBlast is able to build a user profile on you or store your search history.

Finally, the search results are encrypted by GigaBlast using your temporary public key and are returned to you through the Private.sh proxy. The results then get decrypted and rendered locally on your device using Javascript with a temporary private key that only exists on your device. This client-side keypair is changed for every search request.

The search engine itself provides a search field on the start page and options to filter by Web/News or by country. Not all countries are supported but several dozens are including the United States and other English speaking countries, France, Germany or Spain. Most Asian countries don't seem to be supported though.

Results were returned quickly during tests regardless of query or filter.

The search engine shows a text banner for Private Internet Access in a sidebar but has no other ads or unwanted content. A quick check of the network connections shows that it only connects to its own domain plus the subdomain search.private.sh.

Results are quite okay considering that the company that operates the search engine and the index does not have the resources at its disposal that Google or Microsoft have.
