Encryptr Zero-Knowledge System Based Password Manager For Linux

Encryptr is free and Open-Source password manager that is based on a very secure ‘Zero-Knowledge Crypton Framework‘. Zero-Knowledge system does not allow even a server to know what data is being sent and saved on the server by user. Encryptr saves all of your passwords, credit card data, PINs, or access codes, in the cloud with a simple and sleek user interface. The following tutorial instructs installing Encryptr on Ubuntu/Linux Mint or other Debian based distributions.


The best thing about Encryptr that makes it different from other passwords manager or e-wallet is that it is based on Zero-Knowledge Crypton framework. Here is a small description for those who don’t know what Zero-Knowledge Crypton Framework is.

What Is Zero-Knowledge Crypton Framework?

‘Zero-Knowledge’ privacy means the server is never capable of viewing plaintext data; therefore, the data may never be compromised through mismanagement, prying eyes, or external bodies looking to gain access.Crypton is a unique way to build applications, primarily because it makes it simple to store data with a server in such a way that the server doesn’t know what that data is.

How Does It Work?

Working with it is not dissimilar to using a “Backend as a Service”. Crypton-based applications are developed completely on the client, and the server acts as a “dumb pipe” to store and retreive data. There are some exceptions to the dumb pipe rule, such as users must prove that they know an account’s password before their encrypted keyring is sent to them. However, these considerations are abstracted out and application developers need not worry about them.Being such a nice system, there may be a problem if you forget your passphrase because You can not reset it because it was never sent to the server for security reasons.

Encryptr is multi-platform so you don’t have to worry if you use other devices such as Android, Widows tablet and Mac OS X.
