i need to import all users from a dnn 4 site to dnn 5 site.i have already imported all tables.but in membership table the password encryption is different for dnn4 and dnn5. i have register the same user in both sites.and the password and passwordsalt are different in version 4 and 5.so while import users from dnn 4 to 5,i cannot login to the new site.

How to decrypt the old password and encrypt the same for new one?

dnn 4 and dnn6 uses the same password schemes (actually all releases since 3.0 do) - i suspect your problem is that you've not copied across the machinekey values (from web.config) as they're used to encrypt/decrypt the password

that would be because the password is a combination of the password, the password salt and the encryption key -the password salt ensures that the same password does not have the same ciphertext otherwise it would be easy to crack (using rainbow tables)
