I have this method in user.rb that automatically converts password to  
SHA1 hash

```
def password=(value)
    write_attribute("password", Digest::SHA1.hexdigest(value))
end

```

but my user model validations dont seem to work properly…for example  
length\_of and confirmation\_of… cause it gets SHA1 and stuff…

how do I keep it encrypted yet keep validations too?

if I remove the above mentioned method, it works fine but I risk the  
password being naked 😕
