Flutter:MD5加密解密哈希函數
最近更新時間 2019-12-28 20:22:58
純Dart實現的一組加密哈希函數,支持以下哈希算法:
- SHA-1
- SHA-224
- SHA-256
- SHA-384
- SHA-512
- MD5
- HMAC (i.e. HMAC-MD5, HMAC-SHA1, HMAC-SHA256)
安裝
1. 在配置文件 pubspec.yaml中添加依賴,如下所示:
dependencies:
crypto: ^2.1.4
2. 命令行安裝軟件包:
pub get
flutter pub get
3. Import it
import 'package:crypto/crypto.dart';
使用
字符串MD5加密
import 'package:crypto/crypto.dart';
import 'dart:convert'; // for the utf8.encode method
void main() {
var bytes = utf8.encode("foobar"); // data being hashed
var digest = md5.convert(bytes);
print("Digest as bytes: ${digest.bytes}");
print("Digest as hex string: $digest");
}
