Please don't top post. Reply inline or at the bottom.

A keystore file can contain multiple certificates. You just need to specify
which certificate to use and that is done by specifying the "keyAlias"
attribute on your connector.

Ignore what I previously wrote here. You can store hashes of your password in
tomcat-users.xml. To do this, you need to add the "digest" attribute on your
Realm. For the default configuration that would look like this.
<Realm className="org.apache.catalina.realm.LockOutRealm">
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase" digest="SHA-256" />
</Realm>
See here for more details.
