A small utility library for crypto. It declares a class names CryptoUtils which can replace the one in package:crypto. It includes the few methods this class provides.

I created this library because I had a bunch of crypto-related utility functions that I used across different projects and wanted to avoid code duplication.

If you have other crypto-related code you don't want to duplicate, feel free to include it and file a PR.

Currently it includes:

all the methods CryptoUtils from package:crypto
a Codec (including separate encoder and decoder classes) for the following encidongs:
- base64
- base58
- Base58Check
an abstract class Hash and several fixed-sized hash classes, Hash128, Hash160, Hash256, Hash512

Changelog #

0.3.0 #

Remove base58(check) codec because it is in package:base58check
Remove UnmodifiableUint8List (remove zengen dependency)

0.2.1 #

Updated bignum dependency to v0.1.0

0.2.0 #

Changed the library structure to have separate libraries for all aspects and have `cryptoutils.dart`` export them all.
Used ZenGen for delegation so that dart:mirrors is no longer used.

0.1.10 (2015-06-10) #

Updated dependency of bignum to latest version (0.0.6)
Updated dependency of collection to latest version (1.1.1)
