Yet Another Team Password manager? Yes, but there are some unique features:

• scriptability: API to get passwords from Tarkin in your scripts (using authentication token, no need to store username and password in a script)

• unixability: command-line client and interactive shell (no need to run browser if you need some of your passwords!) as well as Ruby Gem with easy-to-use client class

• high security: asynch AES-256 used to store passwords: password is encrypted with group public key, and group private key is ciphered by your public key, so to decrypt the stored password you need your own password to get your private key, which can decrypt the group private key, which is able to decipher the stored password.

• manageability: standard users/groups model, web-based management (so far)

• accessibility: mobile-friendly web (see demo on tarkin.tg.pl)

All passwords are crypted with AES-256 with the group public key. Group private key is ciphered by the user public key. User private key is crypte with user password. Thus, to decrypt the password, you must have user password - this password decrypts the user private key, with which system decrypts the groups private key, which is used to decrypt the password… Sounds complicated? Well, it is completely transparent for the user - you just need to remember your password.

This means that the only group members can read the stored passwords. There is no way to read it even if you have an access to the whole database. This also means that you can’t loose you password to the system. There is no way to retrieve lost password.

UI is based on Zurb Foundation and it is compatible with mobiles.

Passwords are shown only when highlighted. System downloads it on demand via Ajax, so they are not stored in HTML.

Search for items and directories using Unix-like wildcard

You can group your passwords in Unix-like directories and use this folders in URLs to go directly to specified path.

See demo on tarkin.tg.pl to find out more

Command-line client is included into Tarkin Gem - rubygems.org/gems/tarkin - a Ruby Client for Tarkin Server. Find out more on github.com/grych/tarkin-client

$ gem install tarkin

Tarkin API allows you to use it with your own scripts, so you don’t need to store passwords with plain-text anymore and you have one centralized system for all passwords, so you need to change it only in one place.

To not store a password to tarkin in the script, you should generate a token, then you can use this token to authorize:

resp = conn.get("http://localhost:3000/_api/v1/_authorize", email: "[email protected]", password="password0")
token = resp.body if resp.status == 200
#=> "vwbtYjEtZl4IY31HBfJbXD31EUdTLv4stnzVQG8AiiZDagQ3s2IIKcRp..."

in Shell:

OS_TOKEN=`curl "http://localhost:3000/_api/v1/[email protected]&password=password0"`

or, using http authentication:

OS_TOKEN=`curl --user [email protected]:password0 "http://localhost:3000/_api/v1/_authorize"`

then to get specified password use URL: host/_api/v1/Unix-like-path

PASSWORD=`curl -H "Authorization: Token token=$OS_TOKEN" "http://localhost:3000/_api/v1/db/postgres/root"`
