The format of the new keystore(s) is PKCS#12 (files contain a ".p12" suffix).

The password or passwords for new keystores are the same as those for the old keystore. To ensure security, consider changing them as soon as possible with your certificate editing utility.

New keystore files are named according to alias information extracted from a certificate's distinguished name, or DN. If multiple keystores are created, a unique numerical suffix is appended to each file name.
