hashids

What it is

Hashids is a Python implementation of the hashids algorithm that generates short, unique, non-sequential IDs from integers. It's useful for obfuscating database keys and creating user-friendly URLs.

Hashids offers a simple, lightweight solution for generating obfuscated IDs in Python, making it ideal for developers who need to create secure and user-friendly identifiers without complex setup.

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited language support

   Primary implementation is in Python, which may not be suitable for projects using other languages.

2. 02

   Performance limitations with large datasets

   Hash generation can become slow when dealing with a very large number of IDs, impacting real-time applications.

3. 03

   Complex setup for customization

   Customizing alphabet and salt requires careful configuration to ensure uniqueness and security, which can be error-prone.

4. 04

   Small community support

   The project has a relatively small user base compared to more popular ID generation libraries, leading to fewer contributions and slower issue resolution.

What it does well

• Generates short, unique IDs from integers

• Obfuscates database keys for security and privacy

• Supports customization of alphabet and salt
