V4 keystore single
This example demonstrates how to encrypt and decrypt keystore V4 single.

Define an encrypted keystore version 4
Specify the current password of the keystore and a new 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 keystore v3.
