ebics-java-client A006 support ? #44
Description
Hi Uwe
currently I'm starting with the EBICS Java client and have encountered a compatibility issue with our bank that now requires support for the A006 electronic signature procedure. Is A006 support already available in a newer branch, fork, or release?

Add A006 (EMSA-PSS) signature support

Hi,
I added an implementation in the
ebics-a006branch, I did not use it with my bank yet. It would be wonderful if you could try it with your bank and see if it works for you.mstohr1975 commentedon Mar 25, 2026
Hi Uwe,
thanks for your efforts and updates. I'd be happy to test this. Question: To generate the A006 letters, certificates, keystore we simply change in the config.properties the signature.version to A006? Or would we need to a special path for this? I've not found any special logic to generate the A006 letters etc. though.
Many thanks

To use A006, set signature.version=A006 in config.properties.

Thank you, if it worked I will merge it to the main branch and do a new release

@uwemaurer do you know how we could include the certificates into the letters for H005 with certificates?
I mean, we could assemble them afterwards on our own, but is there any path considered in your client?

Hi, many thanks for your work and please excuse my late reply. For testing it with DZ Bank, can I download this completely, then make my changes according to bankparameters and build?

yes sure you can build your own version of the library with the changes you need. Ideally if the changes are useful to others aswell you can send a pull request
