Manpass is an opensource, secure password manager, it has following features:

• Support Windows/Linux/OSX
• Only need to remember one masterpassword
• Use proven highly secure crypto algorithm/implementation
• Double-click to copy password to clip-board, and automatically clear it from clipboard after 20 seconds.
• Show password as QRCode image for mobile device use.
• Instant search among saved credentials (support Pinyin)
• Password history save the past passwords
• Passwords are stored in encrypted form within database, so that the database could reside in cloud storage (e.g. Dropbox) for redundancy and multi-clients synchronization.
• Support multiple Users

Binary build are provided for Windows/Linux/OSX, download from here

Run manpassc, manpassc will start manpassd automatically; for details usage, see help.htm or "Help" in popup menu

manpassc is written in python, manpassd is written in Go. You need following enviroment:

• Python 2.7.10
  • wxpython 3.0.2.0
  • pynacl 0.3.0
  • pyscrypt 1.6.2
  • M2Crypto 0.22.3
  • Pillow 2.9.0
  • qrcode 5.1
• Go 1.4.2
  • go-sqlite3

Manpass has client/server architecture, manpassd is the server which basically is a daemon for credential database, all credentials are stored in manpassd's DB; manpassc is the GUI client talk to manpassd via RESTful API over HTTPS.

• All credentials are stored in encrypted form in manpassd's DB.

• Encryption/decryption is done by manpassc, via NaCl libray

• Each credential is encrypted by a key derived from masterpassword via scrypt algorithm. the derived key is unique for each credential.

• manpassc and manpassd will authenticate each other via certificate, the CA/EE certificate are generated upon new user creation, each user has its own CA/EE certificates. the RSA key and CA certificate are encrypted by user's masterpassword.
