How to update jar signature?

Answer 1

Do you use a self-signed certificate? If so, you just need to use keytool to create a new certificate, and then sign your bank using keysigner.

If you use a third-party signed certificate (Verisign, Thawte, etc.), you will need to renew your key using your online system (usually the same place where you received the original certificate).
