generateNonce method

String generateNonce([
  1. int length = 32
])

Generates a cryptographically secure random nonce of the specified length. Defaults to 32 characters, which is recommended for most use cases.

Implementation

String generateNonce([int length = 32]) {
  const charset =
      '0123456789ABCDEFGHIJKLMNOPQRSTUVXYZabcdefghijklmnopqrstuvwxyz-._';
  final random = math.Random.secure();
  return List.generate(length, (_) => charset[random.nextInt(charset.length)])
      .join();
}
