Hello,
since I prefer to use passwordFormat="Encrypted" instead of "Hashed" DNN7 default, I need to change each user password format, otherwise when I try to change a user password, I got this error:

There was an error setting the password. The password has not been changed.

an exception is thrown:

DotNetNuke.Modules.Admin.Users.Password - System.Configuration.Provider.ProviderException: Hashed passwords cannot be decoded.
at System.Web.Security.SqlMembershipProvider.UnEncodePassword(String pass, Int32 passwordFormat)
at System.Web.Security.SqlMembershipProvider.GetPassword(String username, String passwordAnswer)
at WebMatrix.WebData.SimpleMembershipProvider.GetPassword(String username, String answer)
at System.Web.Security.MembershipUser.GetPassword()
at DotNetNuke.Security.Membership.AspNetMembershipProvider.ChangePassword(UserInfo user, String oldPassword, String newPassword)
at DotNetNuke.Entities.Users.UserController.ChangePassword(UserInfo user, String oldPassword, String newPassword)
at DotNetNuke.Modules.Admin.Users.Password.cmdUpdate_Click(Object sender, EventArgs e)

The users created AFTER the passwordFormat change, have no issue in password change.

Does anyone knows how to change password format for each existing user?

Thanks

what version are you running? Whilst encrypted/hashed for users works fine, we had to make a fix to support the use case where an admin sets a users password (i.e. in the case of a hashed password it's difficult to compare the "old" password value) and this change was only made in 7.1.2

Hi cathal,

when I wrote the post, I had new install of 7.1.1. And I wrote a script in order to convert to encrypt format for each user. Now, I deleted instance and installed 7.1.2. My suprise has been that in this case the token for password reset does not work. The page says that there is no corrispondence between user and token, or token is expired. But I have seen in sql tables that expiration date is 24 hours after token creation and the username is written correctly.

 ...very confused.

that's odd - the password reset page simply looks for a matching resettoken and ensures that it is still valid so as long as you are using the same value for a user that is stored in PasswordResetToken and the PasswordResetExpiration value is in the future it should work i.e. there is no check for existing password
