Android客戶端加密消息，java代碼Cipher cipher = Cipher.getInstance("RSA/ECB/OAEPWITHSHA-256ANDMGF1PADDING");byte[] publicBytes = Base64.decode(Configs.PUBLIC_KEY.getBytes("UTF-8"),Base64.DEFAULT);X509EncodedKeySpec keySpec = new X509EncodedKeySpec(publicBytes);KeyFactory keyFactory = KeyFactory.getInstance("RSA");PublicKey pubKey = keyFactory.generatePublic(keySpec);cipher.init(Cipher.ENCRYPT_MODE, pubKey);String plaintext = "test";byte[] encryptedBytes = cipher.doFinal(plaintext.getBytes("UTF-8"));String chipertext = Base64.encodeToString(encryptedBytes,Base64.DEFAULT);Log.d(TAG,"encrypted (chipertext) = " + chipertext);Golang服務器解密消息，golang代碼func RsaDecrypt(encryptedString string) (string, error) {     base64DecodeBytes, err := base64.StdEncoding.DecodeString(encryptedString)     if err != nil {         return "", err     }     privateKeyBlock, _ := pem.Decode([]byte(privateKey))     var pri *rsa.PrivateKey     pri, parseErr := x509.ParsePKCS1PrivateKey(privateKeyBlock.Bytes)     if parseErr != nil {         return "", parseErr     }     decryptedData, decryptErr := rsa.DecryptOAEP(sha1.New(), rand.Reader, pri, base64DecodeBytes, nil)     if decryptErr != nil {         return "", decryptErr     }     return string(decryptedData), nil}和 golang 中的錯誤： crypto/rsa: decryption error我無法更改服務器上的代碼，那么如何更改 Java 中的代碼？
