Nonce contains a static generator that generates random alphanumeric strings, and can be constructed as an object containing a generated string.
nonce #
[Nonce] contains a static generator that generates random alphanumeric strings, and can be constructed as an object containing a generated string.
Usage #
import 'package:nonce/nonce.dart';
Generator #
The static method [generate] can be used to generate random alphanumeric strings.
[generate] has 3 parameters: [length], [seed], and [secure].
// Generate a string 32 characters long.
print(Nonce.generate()); // Osp54up7WU6P3U97Jz92p9j892n9LP7z
// Generate a string 64 characters long.
print(Nonce.generate(length: 64)); // LDwpr1H74qm894jbd15Lj63wF5RUL07r4L9XOY7zVMz7fLbBCXa68Y6oPw0N9XgV
// Generate a string using a seed.
print(Nonce.generate(seed: DateTime.now().millisecondsSinceEpoch));
// Generare a nonce using a secure [Random].
print(Nonce.generate(secure: true));
generate()
does not rely on Base64 encoding, instead it generates ASCII character codes directly.
Constructors #
[Nonce]'s default constructor constructs a [Nonce] of the specified length; 32
characters by default.
Nonce();
Nonce(64);
unique #
[Nonce]'s [unique] constructor references a global set of every nonce generated by it, and ensures that every nonce returned by it is unique.
Nonce.unique();
Nonce.unique(64);
secure #
[Nonce]'s [secure] constructor generates a unique nonce using a secure [Random].
Nonce.secure();
Nonce.secure(64);
key #
The [key] constructor is shorthand to generate a [unique] nonce 16
characters
in length.
Nonce.key(); // Osp54up7WU6P3U97
