Which is a better technique than URL parameter encryption?
For instance, for the page listed above, the logic implementing that page would check the identity of the currently-logged in user. If the id of the logged-in user matches the producerId of the page parameter, then you show them the information.
What to do if URL parameter does not match?
If the id of the logged-in user matches the producerId of the page parameter, then you show them the information. If the id does not match, you do not show them the information: if it is some other user, you show them an error page (with information about how to get access), or if the user has not logged in yet, you redirect them to a login page.
Can you ever ( safely ) include credentials in an url?
Phishing becomes pointless as there are no credentials to phish independent of the links they are part of. In certain cases, even XSS attacks become less effective, as we shall see later. Many security professionals reading this will baulk at the very idea of putting security tokens into URLs, and with good reason.
Can a username and password be included in a URL?
Way back in the prehistory of the web there was a standard way to encode a username and password into a URL using the following syntax: http://bob:[email protected]/some/path. Here “bob” is the username and “sekret” is the password.
How to encrypt URL parameters in PHP Paragon?
Instead of encrypting URL parameters, add a column that stores a random 12-character string for each row (which is generated by base64-encoding 9 bytes from a CSPRNG ), and use that in your URLs and SELECT queries. (Code snippet above uses paragonie/constant_time_encoding .)
Do you need RBAC for URL parameter encryption?
It does not require modifications to the persistence layer. It doesn’t even require implementing RBAC (role-based access control), but everything is about that function getPrincipalSalesId. It’s basically the same code you use to generate the URL, but this time you hammer that value into the query, making it implicit.
