Re: [security-dev] SHA salted passwords

It's actually currently a unique salt per account, but we need to change it to unique salt per password (see getSalt() method in [1]). I'm also -1 for EncodedPassword, as it doesn't fit the design of the credential handler SPI. What we probably really need is an EncodedPasswordCredentialHandler, similar to [1] which will manage the persistence of a PlainTextPassword however provide a pluggable mechanism for controlling the encoding process. This will require some additional changes though to the SPI to support overriding the default credential handlers (not a major problem though).

Are we using the same salt for every password? 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. >> >> This also brings up a good point with what are our recommendations and defaults?

It clearly tells the user/developer what type of password is being stored. But if he chooses PTP, should we do the default salting/hashing in the background? The EncodedPassword can allow configuration of salting/hashing mechanisms. >>>> >> >>>> >>We should not at any cost save plain text passwords in the tables. >>> >+1 and maybe for a while we could refactor PlainTextPassword to EncodedPassword and avoid some misunderstanding. >>> > >>> >Makes sense? >>>> >> >>>> >>Wdyt? >>>> >> >>>> >> >>>> >>On 01/07/2013 08:14 AM, Pedro Igor Silva wrote: >>>>> >>>Yeah, the class name is not good and leads to confusion. Today you do not need any extra code to get encoded passwords. The code you pointed out is already doing that:https://github.com/picketlink/TODO/blob/master/server/src/main/java/... Behind the scenes it is using SHA-512 and a SecureRandom-1024 salt. Unfortunately, you can not change such configuration for now. Regards.
