Determenistic password generator
Project description
nopassword is a determenistic two factor password generator for the command line
Installation
pip install nopassword
Usage
The generated passwords are stored in your clipboard, enter a seed/key to generate a password
nopassword seed
Example
Generate password using “facebook” as seed
nopassword facebook 6n1eby^@]{dm6T-{]r{5NC^Z^`%vZ9w4.nemgcrN-v&,|,gS3fn]KzXRH,br"$=zf*"v_q@j@
Generate password using “github” as seed
nopassword github k/Mzz-$6AQ\K`1n/mD7]1o0|E'b};RO*ZLzCC]Iuo!oJ#}oB2+a~rx{:o;}&R|O*5k*+u~,%@
As this is determenistic, “github” again will generate the same result
nopassword github k/Mzz-$6AQ\K`1n/mD7]1o0|E'b};RO*ZLzCC]Iuo!oJ#}oB2+a~rx{:o;}&R|O*5k*+u~,%@
Commandline help
nopassword --help

Required arguments:
SEED Seed to generate password
Optional arguments:
-a --alphabet=ascii Character set used: [alphanumeric, ascii, digits]
-l --length=73 Length of generated passwords
-k --keyfile=default Keyfile to use
-i --itterations=113 Number of itterations
Switches:
-h --help Display options and commands
-g --generate Generate new keyfile
Change alphabet to alphanumeric
nopassword github -a=alphanumeric jgddAr2RqhMyNYfYOKLkLUZd8cvnVZcb9tu7yJxa8O2ircJLV9EyhHVm9Lo99eHNTVLMzIj0g
Set password length to 10
nopassword github -l=10 -a=alphanumeric 3HB8VNJ3dd
Set itterations 10
nopassword github -l=10 -a=alphanumeric -i=10 MgHDdXCuUP
Set itterations 11, result different
nopassword github -l=10 -a=alphanumeric -i=11 BBU9FgEamB
Generate new keyfile
nopassword -k=my_organisation -g Keyfile my_organisation created
Use keyfile
nopassword github -l=10 -a=alphanumeric -i=11 -k=my_organisation pZv645w04Z
Keyfiles
Keyfiles are stored in json format in the ~/.nopassword/ directory. Keyfiles kan be shared between devices and individuals, copy the .json file.
ls -lh ~/.nopassword/ total 216K -r-------- 1 oskar oskar 99K apr 11 12:31 default.json -r-------- 1 oskar oskar 99K apr 11 19:21 my_organisation.json
Two factor password generator?
I’d like to think so. Something you got: key file and something you know: seed, iterations and alphabet.
So for a attacker to be able to generate your password they need the keyfile and the parameters.
