nanopass

A quasi-deterministic password management algorithm in ~300LoC

Differences

Nanopass has a few key advantages over other determinstic password managers.

• Flexible password parameters - nanopass can generate passwords with specified lengths and various special character restrictions.

• Mutable master passwords - master passwords can be changed while keeping the same generated passwords, yielding a new vault.

• Password versioning - a single generated password can be updated without a new master password or changing other generated passwords.

Determinstic password generation also has a few differences from a typical manager.

• Trust - nanopass never stores your passwords, encrypted or otherwise.

• Portability - passwords can be generated completely offline, with only a small optional configuration file required.

Config spec

Configuration can be imported a json file with the following format:

[
    {
        "name": "<name>",
        "length": <length>, // password length up to 42
        "version": <version>,
        "special": "<chars>" // excluded special characters
    }                
]
