The Keybase file system developers have finally
released the first alpha release , announced back
in July 2015 . Keybase is a cryptographically secure file repository.
Keybase supports file system level public key encryption. Thus, cryptography is automatically imperceptibly used at all levels of work on the Internet: from file sharing and chat to software verification and control of source code modification. It is possible to use it for authentication on websites, which can make both simple password protection and two-factor authentication unnecessary.
So, in the alpha version of KFMS when writing files to a special directory
')
/keybase/public/yourname
Each file is automatically encrypted, no need to do anything manually, use
tar
or
gzip
. At the same time, the entire content of the directory is displayed on the screen in plain text, there you can drag files with the mouse.
If you know a user in a social network, then his identity (keys) can be checked with the following command.
/keybase/public/malgorithms@hackernews/ /keybase/public/malgorithms@twitter/ /keybase/public/malgorithms@reddit/ /keybase/public/bitcoyne@coinbase/
In this folder, in addition to the SSH public keys, there are a couple more things, like the “fingerprint” for the Signal application and several programs that the owner decided to post and distribute to this audience.
A public key cryptosystem ensures that the user, when connected to a folder, sees exactly what is stored on the disk. The risk of data substitution on the server or MiTM-attacks is excluded.
When you try to connect to the user’s folder via the keybase.io server, this pop-up window with a business card is displayed.
More information - from one of the developers in a text file.
cat /keybase/public/chris/plan.txt
keybase.pub/chris/plan.txt
For demonstration, the site
keybase.pub is running with all the contents of
/keybase/public
.
Keybase's mission is to make public key cryptography available to all users in the world. No need to understand the protocols anymore. Everything works automatically at the file system level. For too long, cryptography has been the lot of selected elites in niche communities, it’s time to extend it to all!
