[security-dev] SHA salted passwords

Mon Jan 7 11:32:45 EST 2013

I've got no problem with that...are there any other types of passwords 
besides text passwords anyway?

I think it might actually be a good idea to remove hashed passwords as an option and instead offer things more secure such as bcrypt or scrypt. One of those at least, imo, should be default. Hashed passwords, even with a salt are really not that secure and I'm not talking about rainbow table attacks, just plain brute force attacks with small box lots of GPU power and some coda code are quickly become the norm for brute forcing passwords.

But if he chooses PTP, should we do the default salting/hashing in the background? The EncodedPassword can allow configuration of salting/hashing mechanisms.

The code you pointed out is already doing that:https://github.com/picketlink/TODO/blob/master/server/src/main/java/org/aerogear/todo/server/security/register/RegistrationEndpoint.java#L85  Behind the scenes it is using SHA-512 and a SecureRandom-1024 salt. Unfortunately, you can not change such configuration for now. Regards.

So, the PlainTextPassword can be used to store encoded password which algorithm will be used behind!
