Introduction and Features

The Python AztecGlyph package is a useful tool for generating unique and secure IDs and keys in the form of 64-bit UUIDs. The AztecGlyph class represents UUIDs that are immutable, hashable, and can be used as dictionary keys. Converting an AztecGlyph object to a string using str() yields a base58-encoded string (URL-safe) that is 11 characters long.

The AztecGlyph class constructor accepts four possible forms of arguments: a string (base58 encoded), a bytes object, an integer, a hexadecimal string, or the values for counter, content type, and timestamp.

The AztecGlyph UUID is divided into three parts: timestamp (41 bits), counter (11 bits), and content type (12 bits).

Property	Bits	Min	Max	description
Timestamp	41	1577836800000	3776860055551	The timestamp is the number of milliseconds elapsed since January 1, 2020.
Counter	11	0	2047	The counter is a number incremented each time a new AztecGlyph is created and reset to 0 each time the timestamp is incremented.
Content Type	12	0	4095	The content type is used to identify the type of data stored in the AztecGlyph.

Requirements and Installation

To use this package, you should have Python 3.x installed. You can install the package using pip:

pip install aztecglyph

Usage and Examples

from aztecglyph import AztecGlyph

# Create a new AztecGlyph from a base58-encoded string (11111111111 to jpXCZedGfVQ)
glyph1 = AztecGlyph(s=base58_string)

# Create a new AztecGlyph from a bytes object
# (b'\x00\x00\x00\x00\x00\x00\x00\x00' to b'\xff\xff\xff\xff\xff\xff\xff\xff')
glyph2 = AztecGlyph(b=byte_object)

# Create a new AztecGlyph from an integer (0 to 18446744073709551615)
glyph3 = AztecGlyph(i=integer_value)

# Create a new AztecGlyph from a hexadecimal string
glyph4 = AztecGlyph(h=hex_string)

# Create a new AztecGlyph with specific counter, content type, and timestamp values
glyph5 = AztecGlyph(counter=counter_value, content_type=content_type_value, now=timestamp_value)

Attributes and Methods

The AztecGlyph class objects have several read-only attributes and methods:

Name	Return Type	Description
glyph.content_type	int	Content Type ID
glyph.str	str	String 11 characters
glyph.int	int	Integer
glyph.bytes	bytes	Bytes object
glyph.hex	str	Hexadecimal string
glyph.timestamp	datetime	Timestamp
glyph.datetime	datetime	Datetime
glyph.counter	int	Counter

Comparing AztecGlyph Objects

AztecGlyph objects can be compared using standard comparison operators such as==, <, <=, >, and >=`. For example:

# Equality check
if glyph1 == glyph2:
    print("glyph1 is equal to glyph2")

# Less than check
if glyph1 < glyph2:
    print("glyph1 is less than glyph2")

# Greater than or equal to check
if glyph1 >= glyph2:
    print("glyph1 is greater than or equal to glyph2")

AztecGlyphField - Django Extension

AztecGlyphField is a Django extension that enables seamless integration of the AztecGlyph library with Django models for generating unique and reliable 64-bit identifiers.

Features and Usage

• Inherits from Django's Field class for easy integration with Django models.
• Generates a unique AztecGlyph UUID for each new model instance.
• Automatically detects ContentType.
• Automatically detects the current timestamp and resets the counter if the timestamp changes.
• One Counter per ContentType per Timestamp.
• Requires Python 3.8 or higher, Django 2.2 or higher, and AztecGlyph 1.0.0 or higher.

To use AztecGlyphField, include it in your models.py file:

from aztecglyph.extensions.django import AztecGlyphField
from django.db import models

class MyModel(models.Model):
   id = AztecGlyphField(primary_key=True)

Then, use it like any other Django model field:

my_object = MyModel()
my_object.save()
print(my_object.id)  # Output: 326ZtZ1QLEJ
