About Random Strings

Random strings are sequences of characters generated using a random or pseudo-random process. They are useful for various purposes, including:

Generating unique identifiers
Creating test data
Generating temporary passwords
Creating unique filenames
Generating API keys or tokens

Common Examples

API Key

Length: 32, Characters: A-Z, a-z, 0-9

Example: xK9pL2mN8qR4sT7vW3yZ5bH6jG1fD0c
