Hi,

I have a DNN 5.6.3 website and the passwords in it are not encrypted.
If we change the password encryption in the webconfig it encrypts passwords for newly created accounts.
But, Is there any way I can encrypt all passwords that are already there in the database?

Regards
Tej

Hi Taj,

I don't know of there's a better answer... but I had a similar problem and had a lot of trouble finding a stock solution. I eventually put together a module that replaces the normal login module. When the user logs in, after running through the normal login process (and if it's successful of course), it would check their existing password format, and, if necessary, change the format. Then, it would run the change password procedure where the new password was the password they entered on the site.

The result is that the user doesn't know it happens, but, the first time they log in, their password is converted to the current format specified in the web.config file.

Hope all's well,

Mike

Mike,

I like your idea. But, how are you changing the password format?
Are you directly updating it in the database aspnet_membership table? Or are you changing it using code?

I tried changing the password format to 2 in the aspnet_membership table and then called the UserController.ChangePassword() but it is giving
me the following error when I give the new password as a string.

"The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or a non-white space character among the padding characters."

Am I missing something here? Or is this not the correct approach at all?

Regards
Tej

Hi Taj,

Yeah, I couldn't find a way to change the format, so I did it directly. Unfortunately, I'm not sure about that error.

Other than changing the format, I used the normal DNN password procedures to do everything else... I think I first reset their password, then I changed it to the value they typed in...
