一、拿到 credentials-config.json 文件

1、打开 Dbeaver 后,点击 “窗口 — 首选项”

2、找到worksapce path

3、进入 workspace path 的文件夹,再进入到 \General.dbeaver 文件夹,找到文件 credentials-config.json (可以备份一下这个文件,万一不小心改了内容)。

二、对 credentials-config.json 文件解码

1、方法一: 如果你有安装 ubuntu、centos 等这些 linux 操作系统,并且系统上安装了 openssl,则可以使用 openssl 对credentials-config.json文件解码(以 centos 系统为例): (1)先把文件复制到 centos 系统某个目录下 (2)还是在这个目录下,使用如下命令

openssl aes-128-cbc -d \

-K babb4a9f774ab853c96c2d653dfe544a \

-iv 00000000000000000000000000000000 \

-in credentials-config.json | \

dd bs=1 skip=16 2>/dev/null

(3)命令执行后,就得到解码后的json字符串(为了方便查看 json 串,可以借助工具 https://www.json.cn/ 查看)

2、方法二: 如果没有 linux 系统和 openssl ,可以用 windows 系统和 java (1)在某个文件夹新建文件 DefaultValueEncryptor.txt ,把下面这段代码粘贴进去保存。

import javax.crypto.Cipher;

import javax.crypto.CipherInputStream;

import javax.crypto.SecretKey;

import javax.crypto.spec.IvParameterSpec;

import javax.crypto.spec.SecretKeySpec;

import java.io.ByteArrayInputStream;

import java.io.ByteArrayOutputStream;

import java.io.InputStream;

import java.nio.file.Files;

import java.nio.file.Paths;

public class DefaultValueEncryptor {

public static final String CIPHER_NAME = "AES/CBC/PKCS5Padding";

public static final String KEY_ALGORITHM = "AES";

private final SecretKey secretKey;

private final Cipher cipher;

public DefaultValueEncryptor(SecretKey secretKey) {

this.secretKey = secretKey;

try {

this.cipher = Cipher.getInstance(CIPHER_NAME);

} catch (Exception e) {

System.out.println("Internal error during encrypted init" + e);

throw new RuntimeException(e);

}

}

public byte[] decryptValue(byte[] value) {

try (InputStream byteStream = new ByteArrayInputStream(value)) {

byte[] fileIv = new byte[16];

byteStream.read(fileIv);

cipher.init(Cipher.DECRYPT_MODE, secretKey, new IvParameterSpec(fileIv));

try (CipherInputStream cipherIn = new CipherInputStream(byteStream, cipher)) {

ByteArrayOutputStream resultBuffer = new ByteArrayOutputStream();

int bufferSize = 100;

byte[] buffer = new byte[bufferSize];

while ((bufferSize = cipherIn.read(buffer)) != -1) {

resultBuffer.write(buffer, 0,bufferSize);

}

return resultBuffer.toByteArray();

}

} catch (Exception e) {

System.out.println("Error decrypting value" + e);

throw new RuntimeException(e);

}

}

public static void main(String[] args) throws Exception {

if (args.length != 1) {

System.err.println("plese input param1: full path to your credentials-config.json file");

System.exit(1);

}

final byte[] LOCAL_KEY_CACHE = new byte[]{-70, -69, 74, -97, 119, 74, -72, 83, -55, 108, 45, 101, 61, -2, 84, 74};

SecretKey aes = new SecretKeySpec(LOCAL_KEY_CACHE, KEY_ALGORITHM);

DefaultValueEncryptor encryptor = new DefaultValueEncryptor(aes);

byte[] credentialsConfigBytesSecret = Files.readAllBytes(Paths.get(args[0]));

byte[] credentialsConfigBytesPlain = encryptor.decryptValue(credentialsConfigBytesSecret);

System.out.println(new String(credentialsConfigBytesPlain));

}

}

(2)然后再把文件名的后缀从 .txt 改为 .java ,并把之前的 credentials-config.json 文件也复制到同个目录下。

(3)cmd 命令行进入到该目录,然后依次执行命令 ,即可。

javac DefaultValueEncryptor.java

java DefaultValueEncryptor credentials-config.json
