QUESTION
I am working on a little package using PHP and MySQL to handle entries for events. After completing an entry form the user will see all his details on a page called something like website.com/entrycomplete.php?entry_id=15 where the entry_id is a sequential number. Obviously it will be laughably easy for a nosey person to change the entry_id number and look at other people's entries.
Is there a simple way of camouflaging the entry_id? Obviously I'm not looking to secure the Bank of England so something simple and easy will do the job. I thought of using MD5 but that produces quite a long string so perhaps there is something better.
...ANSWER
Answered 2021-Jun-01 at 17:28Security through obscurity is no security at all.
Even if the id's are random, that doesn't prevent a user from requesting a few thousand random id's until they find one that matches an entry that exists in your database.
Instead, you need to secure the access privileges of users, and disallow them from viewing data they shouldn't be allowed to view.
Then it won't matter if the id's are sequential.

...ANSWER
Answered 2020-Nov-05 at 02:01Your issue is that you've put all your import
statements inside your class. That makes the variables that get created class variables, which you probably don't want. You're not accessing them as class variables later, so it doesn't look like you intend to be doing this. Furthermore, using a wildcard import like from tkinter.constants import *
is not allowed anywhere but at the top level.
The obvious fix is to move the imports outside the class:
QUESTION
I am developing (with help from SO members) an SPFX webpart(s) which comprises of a form and eventually a workflow that is essentially a glorified approval process with a UI connected to several lists and libraries. After discussing the pros and cons of developing webparts for SP-Online, a developer said a weakness in security was the ability for the end user to simply bypass the web part and go straight to the list or library (if there are no permissions set on that list/library). To seal off the list/lib I am planning on using SharePoint Designer workflows that run on item creation. This workflow will set access to only the creator and any people picker fields in the UI form.
My question is - are there are tips out there or sure fire processes that I can follow that can protect a project such as this from nosey folk?
Apologies to mod's if this isn't in the right place? Can you redirect me if so?
...ANSWER
Answered 2019-Oct-15 at 09:28You could use SecurityTrimmedControl to show or hide components based on the user permissions.
Or custom logic similar as the demo.
Update:
SPFx use current user context(permission) to access SharePoint, so if user could access(CRUD) list data form SPFx, they can get data either by rest api or excel etc.,if you limit user permission for target items, you need other design to bypass this issue(check this thread).
