java后台写法
Cipher cipher = Cipher.getInstance(algorithmName, BouncyCastleProvider.PROVIDER_NAME);
Key sm4Key = new SecretKeySpec(key, ALGORITHM_NAME);
IvParameterSpec ivParameterSpec = new IvParameterSpec(iv);
cipher.init(mode, sm4Key, ivParameterSpec);
return cipher;
android 正确的使用BouncyCastleProvider
Cipher cipher = Cipher.getInstance(ALGORITHM_NAME_CBC_PADDING, new BouncyCastleProvider());
Key sm4Key = new SecretKeySpec(key, "SM4");
cipher.init(Cipher.ENCRYPT_MODE, sm4Key);
cipher.doFinal(plain);
如果安卓 使用BouncyCastleProvider.PROVIDER_NAME 就会报错。要使用new BouncyCastleProvider()
