+  <CH.Code>
+    ```js keystoreV4-single.js
+    const { Wallet } = require("@kaiachain/ethers-ext/v6");
+
+    // Klaytn V4 with one key. kcn account new --lightkdf

+    }`;
+    const password = "password";
+    const newPassword = "newPassword";
+
+    async function main() {
+      const account = Wallet.fromEncryptedJsonSync(encryptedKey, password);
+
+      console.log("decrypted (address, privateKey)");
+      console.log(account.klaytnAddr, ", ", account.privateKey);
+
+      const v3encryptedKey = await account.encrypt(newPassword);
+
+      const newAccount = Wallet.fromEncryptedJsonSync(v3encryptedKey, newPassword);
+
+      console.log("\ndecrypted (address, privateKey) with new password");
+      console.log(newAccount.address, ", ", newAccount.privateKey);
+    }
+
+    main();
+    ```

+
+  從 **@kaiachain/ethers-ext/v6** 軟件包中導入錢包類。
+
+  ```js keystoreV4-single.js focus=1
+  ```
+
+  ---
+
+  定義加密密鑰庫 \*\* version 4\*\*
+
+  ```js keystoreV4-single.js focus=4:20
+  ```
+
+  ---
+
+  指定密鑰存儲的**當前密碼**和**新密碼**。
+
+  ```js keystoreV4-single.js focus=21:22
+  ```
+
+  ---
+
+  使用**當前密碼**加載密鑰庫
+
+  ```js keystoreV4-single.js focus=25
+  ```
+
+  ---
+
+  解密後，您可以訪問**公鑰**和**私鑰**。
+
+  <CH.Code>
+    ```js keystoreV4-single.js focus=27:28
+    ```
+
+    ---
+
+    ```zsh output
+    decrypted (address, privateKey)
+    0xec5eaa07b4d3cbafe7bf437a1ea9a898209f617c ,  0x4062512193ef1dab8ccf3e3d7a4862e3c740bdf11d852954ed48bc73643e354f
+    ```
+  </CH.Code>
+
+  ---
+
+  您可以使用解密密鑰和新密碼生成新的密鑰存儲。  請注意，新的加密密鑰將是 keystore v3。
+
+  ```js keystoreV4-single.js focus=30
+  ```
+
+  ---
+
+  檢查新的密鑰庫 **public** 和 **private** 密鑰，它將與原始密鑰庫不同，因為密鑰庫 v3 \*\* 不支持 klaytn 賬戶系統。
+
+  <CH.Code>
+    ```js keystoreV4-single.js focus=32:35
