V3 keystore

本例演示如何加密和解密 keystore V3。

从 @kaiachain/ethers-ext/v6 软件包中导入钱包类。

已声明加密密钥和密码信息。

您还可以使用 **ethers.Wallet.createRandom().encrypt()**函数创建加密密钥。

使用密码从加密密钥解密账户。

您可以查看账户的地址和私钥。

用另一个密码password2加密账户。它将生成另一个 encryptedKey2.

使用 password2 重新解密来自 encryptedKey2 的 account2 并检查 account2 的地址和私钥是否与来自 encryptedKey 的 account 的信息相同。

执行主函数。
