HarmonyOS开发中， ArkTS如何实现RSA加密？

Answer 1

import { cryptoFramework } from '@ohos.security.cryptoFramework'; 
import { base64 } from '@ohos.util.base64';
 
async function encryptWithRSA(publicKeyStr: string, plainText: string): Promise<string> {
  let context = cryptoFramework.createContext();
  context.setPublicKey(publicKeyStr);
 
  let encryptedData = await context.encrypt(plainText);
  let encryptedStr = base64.encode(encryptedData);
 
  return encryptedStr;
}
 
// 使用示例 
let publicKey = '...'; // 你的公钥字符串 
let plainText = 'Hello, World!';
encryptWithRSA(publicKey, plainText).then(encryptedStr => {
  console.log('Encrypted text:', encryptedStr); 
}).catch(error => { 
  console.error('Encryption failed:', error); 
});
