Should TAN's really allow SPACE characters?
See original GitHub issue- Source File: https://github.com/corona-warn-app/cwa-server/blob/82d2ff55d604f122c7b003adce358979bc7bc7a2/services/submission/src/main/java/app/coronawarn/server/services/submission/verification/tan/TanAuthorization.java#L36

- Question: Should TAN’s really consist of SPACE characters?
The RegEx for reading TANs is done with
^(TAN|TELETAN) ([ a-zA-Z0-9]{6,30})$
This means e.g. this is a valid TAN:
TAN ABCDEF
There are two consecutive SPACES after “TAN”. The first SPACE separating “TAN” and the actual content. The second SPACE is part of the “TAN value” (followed by the “ABCDEF” characters), meaning the value of the TAN is ABCDEF (starting with SPACE).
This would also be a valid TAN (with TAN TAN ANOTHER TAN being the “value” of the TAN):
TAN TAN TAN ANOTHER TAN

Hello together, thanks for the feedback! You are right, this should not be the regex for validating TANs. The reason for this code is that we are still waiting for final specifications. We will change this code to something more sensible once we have that information available.
