This section describes what is a 'keystore' file and what features are supported on 'keystore' files.
"keystore" - A database used by JDK "keytool" command and KeyStore class to store your own private keys,
and public key certificates you received from someone else. "keystore" supports
the following features:
Two types of entries: key entries for private keys and certificate entries for
public key certificates.
A key entry contains the private key and a certificate chain of the corresponding
public key.
Every entry has a unique alias name.
Key entries are protected by separate passwords.
"keystore" may have different implementations from different security package providers.
The default implementation from Sun is called JKS (Java KeyStore).
