keystore_signature 1.0.0

A Flutter plugin to retrieve Android app signature hash keys and convert them into SHA/MD5 hashes in Hex or Base64 format.

Introduction

A Flutter plugin for Android that retrieves the app signature hash keys and converts them into various hash formats (SHA-1, SHA-256, SHA-512, MD5) in Hex or Base64 encoding.

This plugin is mainly useful for registering app hash keys with services like Firebase (hex format) or Kakao Developers (Base64 format).

Usage

This section covers the basic usage of this package and how to integrate it into your application.

Getting Hashed App Keys

import 'package:keystore_signature/keystore_signature.dart';

void main() async {
  // Get SHA-1 hash key in Hex (for Firebase)
  final hexKeys = await KeystoreSignature.digestAsHex(HashAlgorithm.sha1);
  print('SHA-1 Hex Key: ${hexKeys.first}');

  // Get SHA-256 hash key in Base64 (for Kakao Developers)
  final base64Keys = await KeystoreSignature.digestAsBase64(HashAlgorithm.sha256);
  print('SHA-256 Base64 Key: ${base64Keys.first}');
}

Getting Raw App Signatures

// Get the raw app signatures directly from the Android keystore.
// These are the original bytes before being hashed or encoded.
final hashKeys = await KeystoreSignaturePlatform.instance.getSignatures();
print('Raw Hash Key: ${hashKeys.first}');
