After upgrading from 7.0 to 7.2, we are getting errors in our custom registration module. Here is the stack trace:

DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Security.PortalSecurity.Encrypt(String key, String data) at <Company Namespace>.CreateReg(UserInfo& clsUser) at stac<Company Namespace>.btnRegister_Click(Object sender, EventArgs e) --- End of inner exception stack trace ---
When we copy over the Encrypt method into our module, it does not throw an error. However, it does fail again on a different method that requires encryption.

Any help would be greatly appreciated!

Thanks,

Ray

In 7.2.0 we abstracted out the cryptographic items into a provider (so alternative implementations could select other algorithms that might be more secure, harder to crack or meet requirements such as FIPS). As such there is now a provider definition in web.config - if you check your's you should see the following

    <cryptography defaultProvider="CoreCryptographyProvider">

      <providers>

        <clear />

        <add name="CoreCryptographyProvider" type="DotNetNuke.Services.Cryptography.CoreCryptographyProvider, DotNetNuke" providerPath="~\Providers\CryptographyProviders\CoreCryptographyProvider\" />

      </providers>

    </cryptography>

If you don't see that it would suggest there was an issue updating your web.config - which is typically a permissions issue (i.e. it didn't have modify permissions), or that web.config was mistakenly set as readonly (can happen if you check out a copy of a site from source control such as vsts)

Can I add it in manually? And if so, where specifically should it be placed? And lastly, should I change the code I am using to encrypt the password?

Thanks for the quick reply!

yes you can add it manually (add it just below sitemap but before ) - and no, you don't need to change the code. The existing methods call to the provider which uses the old implementation - however having the provider allows us to offer alternative solutions (that would be available for new installs)
