## ◆ protocol

int pace_ctx::protocol

Identifier of the protocol's OID specifying the exact PACE parameters to use.

The OID of the `PACEInfo` structure in the `EF.CardAccess` is used, because it is more specific than the OID contained in the (optional) `PaceDomainParameterInfo` structures.

Accepts the following values:

- `NID_id_PACE_DH_GM_3DES_CBC_CBC`
- `NID_id_PACE_DH_GM_AES_CBC_CMAC_128`
- `NID_id_PACE_DH_GM_AES_CBC_CMAC_192`
- `NID_id_PACE_DH_GM_AES_CBC_CMAC_256`
- `NID_id_PACE_ECDH_GM_3DES_CBC_CBC`
- `NID_id_PACE_ECDH_GM_AES_CBC_CMAC_128`
- `NID_id_PACE_ECDH_GM_AES_CBC_CMAC_192`
- `NID_id_PACE_ECDH_GM_AES_CBC_CMAC_256`
- `NID_id_PACE_DH_IM_3DES_CBC_CBC`
- `NID_id_PACE_DH_IM_AES_CBC_CMAC_128`
- `NID_id_PACE_DH_IM_AES_CBC_CMAC_192`
- `NID_id_PACE_DH_IM_AES_CBC_CMAC_256`
- `NID_id_PACE_ECDH_IM_3DES_CBC_CBC`
- `NID_id_PACE_ECDH_IM_AES_CBC_CMAC_128`
- `NID_id_PACE_ECDH_IM_AES_CBC_CMAC_192`
- `NID_id_PACE_ECDH_IM_AES_CBC_CMAC_256`
