Hello. Cards is some kind of secret knowledge and I can't even ask questions about it because I don't know what to ask... So please tell me what should I buy to make it work and be able to write certificate to the card. |

OpenSC supports such cards/tokens that support some public key cryptographic operation. Whether it is an RSA or an EC signature. This type of operation is necessary to verify the identity of the device/user and is used, for example, for logging in to a remote computer, or browser verification for a WEB server, or creating an openvpn tunnel. Mifare 1k/4k does not support EC or RSA signature/decryption. This is not supported in Mifare DESfire either.. According to the wiki (https://en.wikipedia.org/wiki/MIFARE) MIFARE SAM AV2 has RSA support, but I have never met this card and it is not supported in OpenSC - https://github.com/OpenSC/OpenSC/wiki/Supported-hardware-(smart-cards-and-USB-tokens) In the given link you have a list of supported tokens.. If you plan to store your certificate on the token, you need a non read only card, personalizable card. The list does not include the Yubico 5 token, which supports the PIV standard and is supported in OpenSC, so you can safely use this token as well. Alternatively, if you feel like experimenting a bit, you can also create a token, which is supported in OpenSC, from cheap hardware - the STLINKv2 programmer (google -> "GNUK") |
