Password-Chain (PwChain) is a password manager that enables you to securely manage your passwords and to keep them encrypted on your device via the Advanced Encryption Standard (AES).

Features::
• No request for internet connection; you will feel safe by the fact that your private (decrypted) data are handled offline.
• Database import/export support; backup and restore your encrypted database at either locally or via another app that support file sharing (Dropbox Box Google Drive Email and etc.)
• Password generator; generate strong and complicated passwords with a single click and not have to worry about forgetting them.

Security Design::
In a nutshell your master-password is used along with a random data (salt) to derive a secret-key using PBKDF2. After authentication your secret-key is temporarily stored in memory and acts as a symmetric-key for data encryption and decryption purposes. As for the encryption algorithm the app by default uses AES with a 256-bit key length.
