Re: [keyple-dev] Issue towards using UseCase4 & 10 with SAM-S1 E1
Hi Thillai,

This is a significant step forward! The fact that the secure transaction now goes all the way through is excellent news, as it confirms good communication between your reader, the card, and the SAM.

The final error you're encountering, related to the card's verification of the signature calculated by the SAM, isn't necessarily directly related to the software you're running.

Most frequently, this problem is linked to interference from Windows smart card services. Specifically, these are the "Smart Card Device Enumeration Service" (ScDeviceEnum) and the "Certificate Propagation Service" (CertPropSvc). These services can unfortunately insert invisible exchanges with the card or the SAM, causing the cryptographic calculations to fail.

Could you please try disabling these services and let us know if this resolves the issue?

To check their status before disabling them, you can run the following commands in an elevated Command Prompt (Run as Administrator):

sc query ScDeviceEnum
sc query CertPropSvc

This will tell you whether the services are currently running. You can also check their startup configuration using:

sc qc ScDeviceEnum
sc qc CertPropSvc

To stop and disable the services (again, in an elevated Command Prompt), use:

sc stop ScDeviceEnum
sc config ScDeviceEnum start= disabled

sc stop CertPropSvc
sc config CertPropSvc start= disabled
We remain at your disposal for any further assistance.

Dear Jean-Pierre,

I tried to adapt both of the examples and attached the Console log received.

The adaptation I made was to change the AID to "304554502E494341" and the SFI_ENVIRONMENT_AND_HOLDER to 0x14
(with UseCase10 used SFI_CONTRACTS as 0x15 but unsure about SFI_EVENTS_LOG and SFI_CONTRACT_LIST)

With that it seems it has progressed a bit more in either of the examples but I can't make it work to see it complete gracefully.

It seems to me that the card is not personalized on my side.

Could you confirm and guide me on the right example to start with ?

By the way, it is my first few days working with Calypso:
I see that although a bit of learning curve is required (atleast for me), Keyple is making it far more easier than I thought. Kudos to all of you.

Best regards,

Hi Thillai,

Thanks for reaching out to the Keyple-Dev community and for providing these detailed logs.

Based on our analysis of the logs, the issue doesn't seem to be at the physical communication level. The exchanges between your reader and the card appear to be correct. The errors you're encountering are happening at a higher, application command level.

Specifically, in the log for UseCase10, the OPEN_SECURE_SESSION command fails with a 6A82 status word, which means "File not found". This command is trying to read record 1 of the file located by SFI (Short File Identifier) 0x06.

However, the JSON file generated by the card analysis tool shows that a file with SFI=0x06 does not actually exist on your card sample. This mismatch is the direct cause of the error.

This leads us to the main question: have you adapted the APDU commands in the examples to match the specific file structure of the card you are using?

It seems likely that adapting the SFI and record parameters within the commands to align with your card's actual file system should resolve the issue. The good news is that this suggests your reader is indeed capable of handling the low-level Calypso protocol correctly.

Let us know if adjusting the commands solves the problem.

Best regards,

Jean-Pierre Fortune

Dear Keyple-Dev team,

Good day! I'm Thillai Elayaraja, CTO of ELYCTIS. Currently I'm evaluating Calypso support with our PC/SC readers with a Calypso card sample + SAM acquired from ISRA.

The Calypso card sample is labelled as ST23ZR08 Calypso CD21 Rev 3.1 and
The SAM sample is labelled as INTEROP vFF.E0.42 SAM-S1 E1.

With them I tried the examples UseCase4 and UseCase10 from Keyple but encounter issues detailed below. I tried to adapt those examples to use the reader regex, Card AID (taken from the Card Configuration Audit tool) and also changed the LegacySamUtil.buildPowerOnDataFilter() to use LegacySam.ProductType.SAM_S1E1, with vain. I got to know from one of the CNA contacts to seek help from the Keyple-Dev community and that's where here I'am with the details given below:

Regarding the examples:

  • UseCase4_CardAuthentication:

    Attached the UseCase4_CardAuthentication.log for reference.

    For info, the code stopped at processCommands as below:


  • UseCase10_SessionTrace_TN313:

    Attached the UseCase10_SessionTrace_TN313.log for reference.

    For info, the log ends with the following error:

    [11:01:01:138] [pool-1-thread-1] [ERROR] CardReaderObserver - [Transaction failed with exception: A card command error occurred while processing responses to card commands: OPEN_SECURE_SESSION

Regarding Card Configuration Audit tools:
  • Attached the Tool_AnalyzeCardFileStructure-2.0.3.log and the generated 20250626_CardData_1963796046.json for reference.

  • Attached the Tool_CheckCardFileStructure-2.0.3.log for reference.

With these logs and info, could you help if I need to adapt the examples further to verify the intended use-cases ? And can we "tentatively" say if our reader is capable to support Calypso transactions ?

Thanking you.

With best regards,

Thillai Elayaraja S

P S : Soon we will try to procure the test kits from CNA to validate our readers with all usecases and with the demonstrator app.
