Hi,

I am a rails newbie and I can’t find out how to use act\_as\_authenticated  
with  
an existing user table.

The problem is that I can not figure out how  
to encrypt all existing passwords/logins to the  
fields encrypted\_password/salt for each row in my user table.

The user table is already migrated and the AAA plugin works well with  
new records/users but I also need to convert the remain 28000 records.

Anybody out there who can point me in the right direction?

Thank you  
Chris
