如何使用encrypt在Dart中实现rsa加密

dependencies:
  encrypt: ^5.0.0

import 'package:encrypt/encrypt.dart';

final keyPair = RSAKeyGenerator().generateKeyPair();
final publicKey = keyPair.publicKey;
final privateKey = keyPair.privateKey;

final encrypter = Encrypter(RSA(publicKey: publicKey));
final encrypted = encrypter.encrypt('Hello, World!');
final encryptedText = encrypted.base64;

final encrypter = Encrypter(RSA(privateKey: privateKey));
final decrypted = encrypter.decrypt64(encryptedText);

import 'package:encrypt/encrypt.dart';

void main() {
  final keyPair = RSAKeyGenerator().generateKeyPair();
  final publicKey = keyPair.publicKey;
  final privateKey = keyPair.privateKey;

  final encrypter = Encrypter(RSA(publicKey: publicKey));
  final encrypted = encrypter.encrypt('Hello, World!');
  final encryptedText = encrypted.base64;

  final decrypter = Encrypter(RSA(privateKey: privateKey));
  final decrypted = decrypter.decrypt64(encryptedText);

  print('Encrypted: $encryptedText');
  print('Decrypted: $decrypted');
}
