Importance of the KPK ID and HMK ID
To decipher the contents of a keystore file, it is essential to identify the right KPK and HMK that will do the job. The KPK ID and HMK ID enable you to make this identification. Since these IDs are stored unencrypted in the keystore file header, they can be determined even if you only have access to the keystore file. It is important to choose unique IDs and remember the association of IDs to pass phrases and files to be able to perform a disaster recovery.
