Subject [jira] Commented: (GERONIMO-411) Add Hash Password Rewrite to File Realm

Alan Cabrera commented on GERONIMO-411:
---------------------------------------

I'm not fond of the idea of rewriting the files w/ hashed passwords.  

What do you think about the idea of having the passwords already hashed and that the login
module would do a hash on the password that was entered and compare it against what was in
the file?

The hash that is used can be configurable.

> It would be nice if the properties file realm could rewrite your properties file with
hashed passwords when it reads it.  We would need to be able to recognize hashed vs. unhashed
entries and perhaps even different algorithms.  Perhaps it could go like this:
> user1=plaintext
> user2=MD5{...}
> user3=SHA1{...}
> Anyway, the idea is that this could be a reasonably secure alternative, but you still
wouldn't need to manually hash things to add or update entries -- just put a plain text entry
in and the next time the server reads the file it would hash it for you.
> I guess we'd need to synchronize on the hash operation to avoid threading problems if
multiple apps or whatever use the same properties file, but it shouldn't be bad if we only
rewrite the file if we find any plain text entries.
