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.

A public instance of the HTTP service is available at https://api.hiveeyes.org/vasuki/.

# 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

pip install vasuki

With service API:

pip install 'vasuki[service]'

Please note this software is a work in progress, and its interfaces may change. For those reasons, if you use it as a dependency in your own programs, version pinning is always recommended.

• 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.

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

The fine responder library optionally exposes the machinery as HTTP API.

# UUIDv4
vasuki uuid
d192b464-d32c-48f1-9c23-0fe04a4e8133

# ULID
vasuki ulid
01DEFKXYCJ0E91DQY0YPWZY01D

# Gibberish
vasuki gibberish
shoomly

# MomentName
vasuki moment
Zese

# Nagamani19
vasuki naga19
Xm3k6mWq

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

vasuki gibberish --size medium
schreblyiopp

vasuki slug 42 --format=sixnibble
Baca

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

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

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='.[service,develop,docs,test]'
vasuki --version

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

While some 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, it is important to understand their properties and features when using those identifiers in different contexts. YMMV.

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.
