Hi @tobischo,
You can start reviewing the code.
I'm waiting to finalize tests with our financial partner before putting the PR on ready.

[tobischo]

I am really excited to see that you also added EBICS 3 🤩

I had that on my list as a potential followup after your changes.
Will review as soon as I have time and also start testing whether the 2.5 cases still work that I am responsible
I might have access on a test API to 3.0 as well 🤔

[tobischo]

Overall this looks great.

I haven't tested it yet against an EBICS API, so I cannot speak to whether it is still working (yet).

I think it is missing some test cases, e.g. around the signature algorithm handling and using a different EBICS version

[tobischo]

I think the readme could reflect which one is the default when initializing a new or existing client and how to work with another version

@jplot do you need help finalizing this ?

I don't have a sandbox environment to test end-to-end operation.

I haven't checked if it supports EBICS 2.4, but https://iso20022test.credit-suisse.com/login provides a testing environment for communication through EBICS

Sadly the credit-suisse test ox does not work for ebics 3.0

Es gibt keine Testumgebung; insbesondere eignet sich der
EBICS-3.0-Zugang der Credit Suisse ISO 20022 Test
Platform nicht zum Testen von Direct Link

@tobischo I have reallocated my work time to this project full-time, with the aim of integrating the features related to versions 'H003' and 'H005'.
To ensure compatibility with version 'H005', it was imperative to refactor the way we generate XML.

[tobischo]

Amazing 😃
Let me know when you think it is testable and I will try to at least test the data retrieval cases.
I am not sure I can promise testing the upload part 😅

[frantisekrokusek]

@jplot We have some mandates with H003 servers so we can also do the testing part for you 😉

[jplot]

@frantisekrokusek If you have the possibility of writing more complete tests on the main branch, this would allow me to guarantee the integrity of the new system.

For version H003, I can only confirm that FDL, HAA, HAC, HEV, HIA, HKD, HPB, HPD, HTD, INI, PTK are supported.

[frantisekrokusek]

@jplot we just finished our testing phase on our fork
master...pennylane-hq:epics:master

We have successfully initialized those French banks but only tested INI/HIA/HPB/FDL commands because our mandates do not have access to other commands.

Key Technical Points for H003 and H005 Versions

• AuthSignature: We've observed that the AuthSignature function isn't working correctly on version H003. An investigation is needed to resolve this issue.
• X.509 Certificate Generation: The implementation of X.509 certificate generation will become mandatory for version H005. Therefore, we must ensure this functionality is properly integrated.
• Signature Functions (EMSAs): For version H005, the emsaPssEncode (reference A006) and emsaPkcs1V15Encode (reference A005) signature functions are missing. Their development is crucial for compliance and security.
