Linux PKCS#11 middleware for Athena IDProtect Key v2 (now NXP) — is libASEP11.so available?

[ChaimMarcus]

We use an Athena IDProtect Key v2 smart card token (ATR: 3b dc 18 ff 81 91 fe 1f c3 80 73 c8 21 13 66 01 0b 03 52 00 05 38) issued by our national CA for client-certificate authentication against a government portal. On Windows we use IDProtect Client 7.60.04.

We now need to run the same client-certificate authentication from Linux (Ubuntu 24.04). We understand that Athena Smartcard Solutions is now part of NXP, and that an IDProtect Client for Linux exists (PKCS#11 module libASEP11.so, ASE Cryptoki v3.1) — but it is not available for public download, and our local reseller (ComSign, Israel) does not distribute a Linux build.

Is the Linux IDProtect Client / libASEP11.so available for direct download or request from NXP? If so, how do we obtain it? We've already confirmed the reader/CCID/PC-SC transport layer works fine on Linux (pcscd sees the card, ATR matches, PKCS#11 slot is present) — the missing piece is specifically this vendor middleware, since OpenSC's generic iasecc driver does not fully support this card's personalization.

Any pointer to the right team or download would be very helpful. Thank you.
