Base-64 #

Supports conversion without padding, and
the URL/Filename-safe Base64 conversion.

Available codecs:

• standard (RFC-4648): ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/ (default)
• urlSafe: ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_
• bcrypt: ./ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789

UTF-8 #

Available codecs:

• standard: RFC-3629

BigInt #

Supports both the Big-Endian and Little-Endian conversion

Available codecs:

• msbFirst: treats the input bytes in big-endian order
• lsbFirst: treats the input bytes in little-endian order

Modular Crypt Format (PHC String Format) #

Encoding and Decoding of Hash algorithm output according to the PHC string format specification.

Getting Started #

The following import will give you access to all of the algorithms in this package.

import 'package:hashlib_codecs/hashlib_codecs.dart';

Check the API Reference for details.

Usage #

Examples can be found inside the example folder.

import 'package:hashlib_codecs/hashlib_codecs.dart';
