Security: Preventing Unauthorized Loading/Calls into C++ DLL -


I have C ++ DLL, foo.dll, which provides API methods that give the clayetext answer of encrypted data Are there. I want to come up with a strong solution to allow this DLL to load and use its functions only to manelies (such as user.dll).

This is not the problem of DLL spoofing, but a question of how to hobble a DLL to work only in some contexts I am potentially in non-network context on many platforms, There is no possibility of calling or relying on system calls.

Whatever I have considered, it is a house that uses 'magic key' security, 'do your own roll' is often bad.

Any advice of acceptable methods for this kind of DLL level security?

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
