Samuel Ottenhoff commented on DS-861:
-------------------------------------
It should be possible to re-encrypt all user passwords using the dspace
command-line tool.
Adding a prefix to the user password will be enough for the code to know that
the password has been salted and re-hashed. The user changing the password will
then result in a "clean" (non-prefixed) salted, hashed password.

> Key: DS-861
> URL: https://jira.duraspace.org/browse/DS-861
> Project: DSpace
> Issue Type: Improvement
> Components: DSpace API
> Affects Versions: 1.7.0
> Reporter: Alex Lemann
>
> DSpace does not store and use salted hash passwords for local database based
> authentication (PasswordAuthentication). This constitutes a security risk in
> that given a database dump an attacker can more easily crack passwords using
> a rainbow table. For more information see the wikipedia article on salting
> password hashes:
> http://en.wikipedia.org/wiki/Salt_(cryptography)
> Possible Tasks:
> Create new configuration parameter for the salt value
> Automatically generate a securely random hash for new projects
> Document new configuration option & install information
> Store salted hashes in passwords in DB
> Use salt for authentication
