大佬你好，目前支持des-ecb中的pkcs7吗？

并且运行之后还报了一个错误
flutter: type 'Future<Uint8List?>' is not a subtype of type 'FutureOr<List>' in type cast

flutter doctor -v
看一下flutter版本

[qllqll]

Flutter (Channel master, 2.10.0-1.0.pre.281, on macOS 11.3.1 20E241 darwin-x64,

目前 stable 是没有问题的，建议使用稳定版
[✓] Flutter (Channel stable, 2.10.0, on macOS 12.2 21D49 darwin-x64, locale

大佬，还是一样的，是我打开的方式不对么
flutter: type 'Future<Uint8List?>' is not a subtype of type 'FutureOr<List>' in type cast

我已经换了成
Flutter is already up to date on channel stable
Flutter 2.10.0 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 5f105a6ca7 (7 天前) • 2022-02-01 14:15:42 -0800
Engine • revision 776efd2034
Tools • Dart 2.16.0 • DevTools 2.9.2

我是用encryptToBase64 这个方法会这个报错

[qllqll]

List.from()用这个转就不会报错了

[OctMon]

final_key = "u1BvOHzUOcklgNpn1MaWvdn9DT4LyzSX";
final _iv = "12345678";
final _text =
"Java, android, ios, get the same result by DES encryption and decryption.";
await FlutterDes.encryptToBase64(_text, _key, iv: _iv);
我这里是正常的，方便看下你的代码不？

[qllqll]

const string = "123456";
const key = "1644288237811";
const iv = "12345678";

try {
  var encryptBase64 =  await FlutterDes.encryptToBase64(string, key,iv: iv);
}catch(e){
  print(e);
}

[qllqll]

就这样的 和你的没啥区别

[qllqll]

还有个问题 为啥你这加密出来的不一样啊 oc代码如下
#pragma mark - DES加密方法

• (NSString *) encryptUseDES:(NSString *)plainText key:(NSString *)key
  {
  NSString *ciphertext = nil;
  const char *textBytes = [plainText UTF8String];
  NSUInteger dataLength = [plainText length];
  unsigned char buffer[1024];
  memset(buffer, 0, sizeof(char));
  //const void *iv = (const void *)[gIv UTF8String];//CBC 需要才矢量
  size_t numBytesEncrypted = 0;
  CCCryptorStatus cryptStatus = CCCrypt(kCCEncrypt, kCCAlgorithmDES,
  kCCOptionPKCS7Padding|kCCOptionECBMode,
  [key UTF8String], kCCKeySizeDES,
  NULL,
  textBytes, dataLength,
  buffer, 1024,
  &numBytesEncrypted);
  if (cryptStatus == kCCSuccess) {
  NSData *data = [NSData dataWithBytes:buffer length:(NSUInteger)numBytesEncrypted];
  ciphertext = [[NSString alloc] initWithData:[GTMBase64 encodeData:data] encoding:NSUTF8StringEncoding];
  }
  return ciphertext;
  }

我这边没问题的

[qllqll]

我试了你的工程的 是没问题 但是引入包就有问题，我也感觉奇怪

[OctMon]

用Swfit写吧

[qllqll]

工程中是des_ecb PKCS7Padding 不知道为啥和你的加密出来不一样

[OctMon]

对照着 http://tool.chacuo.net/cryptdes 这个，选一样的方式，看看结果

[qllqll]

我和网站加密出来是一样的 只是偏移量没有 填充是PKCS7Padding
