java - BadPaddingException: Decryption error

问题描述

问 题

1. 使用golang做rsa加密，java解密出现点问题

  public static byte[] rsaDecrypt(String cryptograph, String private_key) throws Exception {
    BASE64Decoder b64d = new BASE64Decoder();
    byte[] keyByte = b64d.decodeBuffer(private_key);
    PKCS8EncodedKeySpec s8ek = new PKCS8EncodedKeySpec(keyByte);
    KeyFactory keyFactory = KeyFactory.getInstance("RSA");
    PrivateKey privateKey = keyFactory.generatePrivate(s8ek);
    Cipher cipher = Cipher.getInstance("RSA/ECB/OAEPWithSHA1AndMGF1Padding");
    cipher.init(2, privateKey);
    BASE64Decoder decoder = new BASE64Decoder();
    byte[] b1 = decoder.decodeBuffer(cryptograph);
    return cipher.doFinal(b1);
  }

func RsaEncrypt(data string) (string, error) {
    encrypt, err := rsa.EncryptOAEP(sha1.New(), rand.Reader, publicKey, []byte(data), []byte(""))
    if err != nil {
        return "", err
    }
    return base64.StdEncoding.EncodeToString(encrypt), nil
}

报错信息：

javax.crypto.BadPaddingException: Decryption error

解决方案

临时犯傻！　用的公钥和私钥不是一对　　已解决
