Classes

Utils

This class provides utility functions. The createGuid() method generates a unique GUID string. It uses the crypto module to generate random bytes and convert them to hexadecimal values. The generated GUID follows the pattern xxxxxxxx-xxxx-4xxx-8xxx-xxxxxxxxxxxx, where each x is replaced with a random hexadecimal digit.
