I am working on a use-case where OpenPGP is being used to generate a public key pair on a smart card (Yubikey). The smart card is then to be shipped off to the user. Trying to emulate this locally the following is being done: generate keys on smart card; remove GnuPG home directory; access smart card to re-generate GnuPG home directory
Generating or verifying an authentication cryptogram uses the S-ENC session key and the signing method described in appendix B.1.2.1 - Full Triple DES.

There are several solutions which you can use to communicate with your smart card via this library. Such as: pkcs11-tool (CLI interface), PyKCS11 (python wrapper). Here is an example how it could be achieved with PyKCS11: # get slot value via pkcs11.getSlotList(tokenPresent=False). Usually it's 0. If you create the byte[] with the SecretKeySpec then the key must come from memory. That means that the key may be put in the secure token, but that the key is exposed in memory regardless. Normally, secure tokens only work with keys that are either generated in the secure token or are injected by e.g. a smart card or a key ceremony. So these are the steps I use to debug a smart card 1) Open Smart Card with Window and read the card with a file explorer. Once card is open with explorer it will stay open until you turn off machine. 2) Read Card from a c# application (after unlocking with explorer) to verify the size of the address and data 3) Unlock card with c# application. 2.

Turn on NFC. 2. Open the NFC Card Emulator. 3. Put the NFC card on the back of the phone. After the identification is successful, enter a card name and save it. 4. Clicking the card’s “simulate” button, simulates the .Smart Card Emulator. Use your phone as contact-less smart card. The Android Smart Card Emulator allows the emulation of a contact-less smart. card. The emulator uses Android's HCE to fetch process APDUs from a NFC .
