Andrew Jaquith commented on JSPWIKI-20:
---------------------------------------
One thing I should have added in the Javadoc is that hashes are updated
transparently whenever the password is changed, OR upon successful login.
Otherwise, if the hash is still in the old format, we keep it that way. It's
quite transparent to the user and admin.
> Password hash should be salted

> The password hash is calculated as a direct SHA1-digest of the password.
> Unfortunately this means that it's vulnerable to brute-force attacks - there
> are many web sites which store SHA1 hashes of common passwords. The key
> space in most languages is pretty small... So the password should really be
> properly salted with preferably a long, random string.
