GPwd Commandline Python Password Manager

Program for retreiving passwords from an encrypted file and pushing them neatly to the clipboard.

Requirements:

• Linux
• xclip [clipboard]
• Python >= 3.0
  • PyCrypto pip install pycrypto

How is this different from any other password manager?

Most password managers appeal to the masses and utilise clunky GUIs, wasting system resources and complicating the process. I wanted to create a simple password manager which:

• runs simply from the commandline
• integrates into the system for automation
• uses intelligent string matching
• is uncomplicated and fast
• gives the user complete control

Usage:

Note that in all get cases, the name of the service doesn't have to be an exact match. The program will find the closest match. If no matches are found, the program will exit with an error message.

Set new login details

gpwd set [name of service] [parameters] Valid parameters:

--service -s --username -u --password -p --email -e --name -n --phone -q --info -i --domain -d

Options

-x n Generate random password of length n. Write to file and copy to clipboard. If n is omitted, default of 10 is used.
--quiet Don't write anything to stdout.

Return Values: [1] Success! [output info] [0] [Error Message]

Example:

gpwd set -x 8 -s youtube -u mychannel -e 'superb@email.com' -n 'Alice Wonderland' -q '+61411856144'
> 'Generating password...'
> 'Success | Details saved.'

Get commands

• Print the information on a given service
  gpwd info [service(s)]
  Example:

  gpwd info youtube
  > username:   supercoolkid
  > email:      super@cool.kid
  > password:   strongpwd123
  

• List all services
  gpwd list
  Example:

  gpwd list
  > github    github.com
  > facebook  facebook.com
  > twitter   twitter.com
  > youtube   youtube.com
  > ...
  

• Copy password to clipboard
  gpwd pwd [service]
  Example:

  gpwd pwd github
  > Password for Github copied to clipboard.
  

• Print login credentials
  gpwd get [service]
  Example:

  gpwd get gmail
  > url:      https://gmail.com/
  > email:    email@gmail.com
  > password: mypassword123
  > phone:    +1 1234 345 678

* * * ## How does it work? When a user sets a new service file they will be prompted to enter their master key. Now, a new file is created with a lowercased filename equal to the entry in **--service**. The file is encrypted with the master key from plaintext, with the contents having the following format: u username \n p password \n e email \n n name \n d domain \n q phone \n i info \n

• Necessarily, all newlines in entries will be removed and replaced with spaces.
• Entries which are too long [over 256 chars] will cause the program to exit.

On a get command, the program will likewise request the master key, before decrpyting the file and retreiving the required information.

Todo

• Allow for custom credential parameters in the set function.
• Allow user to specify the encryption spec
• Allow authentication over a specified period
  • Eg. after 10 minutes, the user must enter master password to continue
  • Implement by storing a hash of password in a temp file for validation. Requies a background process to re-encrypt when interval is up.
  • Increases attack surface
