Broken since PSD2

[agross]

After PSD2 has been enabled on September 12 the library no longer works although strong authentication has been completed once in the 90-day timeframe. Can you please adjust the code so it works again?

Errors look like this (netbank):

FinTS::DialogError:
       {"9050"=>"Die Nachricht enthält Fehler.", "9075"=>"Starke Kundenauthentifizierung notwendig.", "9800"=>"Dialog abgebrochen", "9340"=>"Ungültige Auftragsnachricht?: Ungültige Signatur."}

Renault Bank:

FinTS::DialogError:
       {"9050"=>"Die Nachricht enthält Fehler. (TRE)", "9075"=>"Starke Kundenauthentifizierung notwendig. (TRE)", "9800"=>"Dialog abgebrochen (TRE)", "9340"=>"Auftrag abgelehnt. (TRE)"}

Hi Alexander, we’re also seeing this issue but right now we don’t have any capacity to fix this as it seems to require bigger changes to the library.

Our de-facto upstream python experiences issues as well: raphaelm/python-fints#72. Once a fix has been implemented there we might port it to this library.

@mkilling From the changes in the python-fints repo it seems that they basically catch the 9075 response (strong auth needed) and then start a TAN process. Is there any code to do any TAN processing in ruby_fints?

Hi @coezbek not right now, the ruby_fints codebase is basically a translation of python-fints from July 2017. It should be pretty straightforward to port the python-fints changes for PSD2, but I unfortunately don’t have time to work on that right now. It would be amazing if you or anyone could provide a pull request - I’ll be happy to review + merge it.
