1. CryptAcquireContext
   • Acquire a handle to the default container on the card
   • The calling process specifies the CRYPT_MACHINE_KEYSET and CRYPT_SILENT flags
   • Returns handle to default container context (#C1)
2. CryptSetProvParam
   • Present the PIN to the card (#C1)
3. CryptGetUserKey
   • Get a handle to the key exchange key pair in the default container (#C1)
4. CryptGetKeyParam
   • Called to retrieve the size of the certificate on the card (#C1)
   • Returns the certificate size in bytes
5. CryptGetKeyParam
   • Called with a buffer of sufficient size to read the certificate off the card
   • Returns the certificate data in the data buffer (#C1)
6. CryptSetProvParam
   • Present the PIN to the card (#C1)
7. CryptGetProvParam

12. CryptAcquireContext
    • Acquire a handle to the default container on the card
    • The calling process specifies the CRYPT_MACHINE_KEYSET and CRYPT_SILENT flags
    • Returns handle to default container context (#C2)
13. CryptSetProvParam
    • Present the PIN to the card (#C2)
14. CryptGetProvParam
    • Called with the PP_ENUMALGS parameter and the CRYPT_FIRST flag to get information about the first algorithm supported by the CSP (card) (#C2)
    • Returns a PROV_ENUMALGS structure filled out with information about the first algorithm
15. CryptSetProvParam
    • Present the PIN to the card (#C2)
16. CryptGetProvParam
    • Called with the PP_ENUMALGS parameter to get information about the next algorithm supported by the CSP (card) (#C2)
    • Returns a PROV_ENUMALGS structure filled out with information about the next algorithm

    Repeat 15, 16 until all algorithms enumerated

17. CryptSetProvParam
    • Present the PIN to the card (#C2)
