V4 keystore single
This example demonstrates how to encrypt and decrypt keystore V4 single.
Import the Web3 class from the @kaiachain/web3js-ext package.
Set up the provider and define a web3 instance using the provider.
Define an encrypted keystore version 4
Specify the current password of the keystore and a new password.
Load the keystore with its current password
After decryped, you can access the public and private key.
You can generate a new keystore using the descrypted key and a new password. Note that the new encrypted key will be a keystore v3.
