> An offhand comment by [~dlofthouse] got me thinking about a possibly major simplification and improvement to the file system realm.
> Right now it uses XML to store the identity and all its credentials; this is fairly complex and also not very secure.
> As an alternative approach, the realm could be rewritten to store each identity in two parts: authentication information and authorization information.  The authentication information could consist of a KeyStore (probably a org.wildfly.security.keystore.WrappingPasswordKeyStore which could be enhanced to support modular crypt or another general format of password), whose aliases correspond to credential names.  The authorization information could simply be a properties file which is loaded in to become Attributes.  Recent identities could be cached for efficiency.
> This would massively simplify the realm implementation, and also improve the security of the stored credentials.
