Build Status

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:
  • an abstract class Hash and several fixed-sized hash classes, Hash128, Hash160, Hash256, Hash512



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


  • Updated bignum dependency to v0.1.0


  • 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)

  • The description is too short.

    Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

  • Package is pre-v1 release.

    While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction API.

  • Maintain an example.

    Create a short demo in the example/ directory to show how to use this package. Common file name patterns include: main.dart, example.dart or you could also use cryptoutils.dart.

  • Fix analysis and formatting issues.

    Analysis or formatting checks reported 2 hints.

    Strong-mode analysis of lib/encoding/base64.dart gave the following hint:

    line: 445 col: 14
    The method '_divmod256' isn't used.

    Run dartfmt to format lib/hash.dart.
