HarmonyOS 关于HarmonyOS开发中AES/RSA加密的填充模式该如何填写？

Question

最近在做接口加密，用到RSA加密和AES加密，这个填充模式我感觉没有填对，导致卡住了， 服务端接到数据解密不了，具体代码看图片。

Answer 1

RSA加密和AES加密的填充模式，请参考以下代码片段

//RSA
// 加密消息
async function encryptMessagePromise(publicKey: cryptoFramework.PubKey, plainText: cryptoFramework.DataBlob) {
  let cipher = cryptoFramework.createCipher('RSA1024|PKCS1');//***此处 pkcs1为填充方式 尽在加解密的cipher 声明
  await cipher.init(cryptoFramework.CryptoMode.ENCRYPT_MODE, publicKey, null);
  let encryptData = await cipher.doFinal(plainText);
  return encryptData;
}
// 解密消息
async function decryptMessagePromise(privateKey: cryptoFramework.PriKey, cipherText: cryptoFramework.DataBlob) {
  let decoder = cryptoFramework.createCipher('RSA1024|PKCS1');//***此处 pkcs1为填充方式 尽在加解密的cipher 声明
  await decoder.init(cryptoFramework.CryptoMode.DECRYPT_MODE, privateKey, null);
  let decryptData = await decoder.doFinal(cipherText);
  return decryptData;
}

//AES
// 加密消息
async function encryptMessagePromise(symKey: cryptoFramework.SymKey, plainText: cryptoFramework.DataBlob) {
  let cipher = cryptoFramework.createCipher('AES128|CBC|PKCS7');//***此处 pkcs7为填充方式 尽在加解密的cipher 声明
  let iv = genIvParamsSpec();
  await cipher.init(cryptoFramework.CryptoMode.ENCRYPT_MODE, symKey, iv);
  let cipherData = await cipher.doFinal(plainText);
  return cipherData;
}
// 解密消息
async function decryptMessagePromise(symKey: cryptoFramework.SymKey, cipherText: cryptoFramework.DataBlob) {
  let decoder = cryptoFramework.createCipher('AES128|CBC|PKCS7');//***此处 pkcs7为填充方式 尽在加解密的cipher 声明
  let iv = genIvParamsSpec();
  await decoder.init(cryptoFramework.CryptoMode.DECRYPT_MODE, symKey, iv);
  let decryptData = await decoder.doFinal(cipherText);
  return decryptData;
}
