# Which Problems Are Solved
As part of #11035 , this PR implements the IDP intent check logic for
session validation
# How the Problems Are Solved
- Inject encryption algorithm for IDP intent tokens at DB initialization
- Add the IDP intent repository as an invoke option
- Rework crypto mocks using gomock
- Implement IDP intent check logic
- minor - DB: expand IDP Intent deletion testing table with a test case
where IDP intent is not found
# Noteworthy
I did not implement `domain.Transactional` given the doubts that
@adlerhurst expressed in https://github.com/zitadel/zitadel/pull/11804 .
So, there is no transaction AT ALL in here because the `Execute()`
method contains one single DB call (Delete) and `Validate()` just does
Get calls.
