Introduction to Random.Secure Dart

Random.Secure Dart is a package for generating cryptographically secure random values in Dart programming language. This package ensures that the generated random values are unpredictable and non-deterministic, making it suitable for use in security-critical applications.

Installation

To use Random.Secure Dart in your Dart project, add the following dependency to your pubspec.yaml file:

dependencies:
  random_secure: ^1.0.0

Then, run pub get to install the package.

Usage

To use Random.Secure Dart in your Dart code, import the package:

import 'package:random_secure/random_secure.dart';

Then, you can use the randomInt() function to generate cryptographically secure random integers:

int randomValue = randomInt(100);
print(randomValue); // prints a random integer between 0 and 99

You can also use the randomString() function to generate cryptographically secure random strings with a specified length:

String randomString = randomString(16);
print(randomString); // prints a random string with 16 characters

Security

Random.Secure Dart uses the dart:math library for generating pseudo-random values, and the dart:io library for obtaining cryptographically secure random values from the operating system's random number generator.

Note that the security of the generated random values depends on the quality of the random number generator provided by the operating system. It is recommended to use a modern, up-to-date operating system with a secure random number generator for maximum security.

Conclusion

Random.Secure Dart is a useful package for generating cryptographically secure random values in Dart programming language. With its easy-to-use API and strong security guarantees, it's a great choice for security-critical applications.
