Epson offers the TSE Service to verify the validity of the certificate and general correctness of generated TAR archives for all Epson TSEs. Also, it allows to revoke the certificate of a Epson TSE.
The service offers the following functionality:
1. Certificate Information
On tab ‘Certification Information’, the current state of a certain TSE’s certificate can be queried.
The data can be queried either by entering the TSE Serial Number or by uploading the ‘TSE_INFO.DAT’ file.
The returned information includes the certificate expiration date, whether the TSE’s certificate has been revoked and if it has, the reason and the revocation date. Additionally, the certificate chain is returned.
2. TAR Archive Check
On tab 'TAR Archive Check', a TAR archive can be uploaded and checked for validity. Please note that the TAR archive must have been created by a TSE to pass validation.
Please note, that only the first 10kb of the selected file get uploaded, so it is perfectly fine to select a big TAR archive for upload, since its size will automatically be reduced during transfer.
3. Revoke Certificate
On tab ‘Revoke Certificate’, a TSE’s certificate can be revoked permanently. Revoking a certificate is recommended in case the TSE has been lost.
Revoking a certificate requires the TSE’s serial number and its revocation password, which is delivered to the customer as part of the delivery process of the TSE.
Please note that revoking a certificate can not be undone and has the consequence that tax inspections may not accept signatures made by this TSE from the date of revocation onwards.
Only officially produced Epson TSEs that are meant for use in the field are supported by this service.
Epson Development TSEs are not known to the service.
What does the TAR Archive Check validate?
It will be checked that a valid certificate is stored inside the TAR archive and that this certificate belongs to a Epson TSE. Also, the first Log Message will be extracted and its signature will be checked against the public key of the known certificate to ensure that Log Messages are properly signed.
What does the TAR Archive Check NOT validate?
The check does not validate the data that a cash register stores inside the Log Message. This especially means that it will not perform a DSFINV-K or DFKA taxonomy compliance check. Compliance to the relevant fiscal specifications must be ensured by the cash register vendor.
Does the service process the entire TAR file that is being uploaded?
No, only the first 10kb of the TAR archive will actually be uploaded and validated.
Can I upload the TAR archive directly from the TSE storage?
Yes, as long as the TSEs self test has been passed, you can directly upload the 'TSE_TAR.001' file from the TSE storage. The service will make sure to not upload the entire 1gb file, but only the first 10kb.
Does the service store any data from the uploaded TAR archive?
No, the data is not stored persistently, but gets analyzed on the fly in volatile memory only and gets discarded afterwards.
What are the consequences of revoking a certificate?
Certificate revocation invalidates all signatures that are created from the date of revocation onwards with the consequence that tax inspections may not accept signatures that have been created by the corresponding TSE after the revocation date. All previously created signatures remain valid.
Certificate revocation is strongly advised in case the TSE has been lost.
