Switch branches/tags

Name already in use

A tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Are you sure you want to create this branch?

Password Manager

Password Manager allows to store its passwords in a centralized and secure way. Indeed the passwords are encrypted on the client workstation with the current standards (see details below). Thus, the web service never has clear passwords in its possession, and has no way to decipher them.

Password Manager

Google Chrome / Opera / Vivaldi extension

The extension for browsers based on Chromium (Google Chrome, Opera, Vivaldi) automatically fills the form of the current page.

Password Manager


It is possible to replace the extension with a bookmarklet. To do this, create a bookmark with the following url:

javascript:document.location = "meziantoupasswordmanager:search?url="+ encodeURIComponent(document.location.href)


  1. Upon creation of the user account, a bi-key (RSA) is generated on the client computer
  2. The private key is encrypted with the master key
  3. When creating a password, it is encrypted with a unique generated 256-bit AES key
  4. The AES key is encrypted with the public key of the user

=> All encryption operations are performed on the client computer (not on the server). Moreover, the web service never has the private key in its possession and therefore can not decipher the passwords.

Sharing of passwords

It is possible to share an entry with another user of the service:

  1. The AES key of the password is decrypted with the private key
  2. The application retrieves the public key of the user with whom the password is shared and encrypts the AES key using it
  3. The encrypted key is sent to the service
