Vasuki

About

Vasuki generates different kinds of random unique identifiers, tokens, and words. It can be used as a library and as an HTTP service, aiming to provide effortless identifier generation for your applications.

Install

Prerequisites

pip install vasuki

With service API:

pip install 'vasuki[service]'

Features

Unique ID generators

• UUIDv4 universally unique identifier

• ULID universally unique lexicographically sortable identifier

• Gibberish random, pronounceable pseudo-words

• MomentName, a short epoch slug

• Nagamani19, a short, unique, non-sequential identifier based on Hashids and a custom Epoch starting on January 1, 2019.

Time and randomness is usually taking from the system as implemented by the libraries underpinning this package.

Slugifiers

• six-nibble-name converts six nibbles (three bytes) into a 4-character name

Optional service API

The fine responder optionally exposes the machinery as HTTP API.

Synopsis

# UUIDv4 universally unique identifier.
vasuki uuid

# ULID universally unique lexicographically sortable identifier.
vasuki ulid

# Gibberish random, pronounceable pseudo-words
vasuki gibberish

# MomentName short epoch slugs
vasuki moment

# Nagamani19 short, unique, non-sequential identifier.
vasuki naga19

Examples

Identifier generation

# UUIDv4
vasuki uuid

# ULID
vasuki ulid

# Gibberish
vasuki gibberish
shoomly

# MomentName
vasuki moment

# Nagamani19

With transformations

Vasuki can apply uppercase or lowercase transformation to the generated identifier or word:

# UUIDv4, uppercase
vasuki uuid --upper
43FA0272-CA48-40AE-8CC1-204302D91D89

# ULID, lowercase
vasuki ulid --lower
01defkz01k47dqkvcyhy0mz06e

With variable word length

vasuki gibberish --size medium
schreblyiopp

Slug tools

vasuki slug 42 --format=sixnibble
Baca

Multiple tokens at once

vasuki naga19 --count 10
vasuki gibberish --size large --count 50

HTTP API

Start the Vasuki service as daemon:

vasuki service

Example requests would look like:

# UUIDv4
/unique/uuid

# Uppercase UUIDv4
/unique/uuid?upper=true

# Multiple ULIDs
/unique/ulid?count=10

# Very short Nagamani19
/unique/naga19?size=small

Development

Acquire sources:

git clone https://github.com/daq-tools/vasuki
cd vasuki

Install development sandbox:

python3 -m venv .venv
source .venv/bin/activate
pip install --editable=.[develop,docs,test]
vasuki --version

Run linter and software tests:

poe check

Disclaimer

The algorithms and procedures curated here generate different kinds of random and pseudo-random identifiers, tokens, names or passwords.

While some of the generated tokens max out on the randomness and uniqueness aspects like UUIDs, others compromise on the time vs. space domain but focus more on human memorability and empathize with their common sense and humor.

Saying that, you should know what about their properties and features when using those identifiers in different contexts. YMMV.

Etymology

Kurma is one of the avatars of Vishnu. He appears in the form of a tortoise or turtle to support the foundation of the cosmos, while the gods and demons churn the cosmic ocean with the help of serpent Vasuki to produce the nectar of immortality.

Vasuki is a naga serpent king, occasionally coiling around Kurma’s or Shiva’s neck, who blessed and wore him as an ornament. He is described as having a gem called Nagamani on his head.
