cryptacquirecontext smart card Obtains a context for a smart card CSP that can be used for hashing and symmetric key operations but cannot be used for any operation that requires authentication to a smart card using a PIN. This type of context is most often used to perform operations on an empty smart card, such as setting the PIN by using CryptSetProvParam . TIGER TALK. Thursdays at 6 p.m. CT.

for example you could access smart card directly via .

for example you could access smart card directly via CryptAcquireContext(&hProv,"\.\\",.) where reader name is card reader name and container name is whatever rsa.KeyContainerName in code snippet above. I'm using Crypto API's CryptAcquireContext function (https://learn.microsoft.com/en-us/windows/desktop/api/Wincrypt/nf-wincrypt-cryptacquirecontexta) to get access to my Certificate Store contained on my USB Token, and this is working like a charm! I'm using Crypto API's CryptAcquireContext function to get access to my Certificate Store contained on my USB Token, and this is working like a charm! However, the CryptAcquireContext function is deprecated and the Crypto API documentation recommends the use of CNG to achieve the same results.
It now uses unmanaged Crypto API to enumerate the names of all containers managed by Microsoft Base Smart Card Crypto Provider and then searches for the corresponding X509Certificate2 objects in the CurrentUser\My store.How can I get the name of a Key Container that's in a smart card required for initialization of CspParameters? CspParameters^ cspa = gcnew CspParameters(ProviderType, ProviderName, keyContainerName, cryptoSecurityKey, securityString); RSACryptoServiceProvider^ csp = gcnew RSACryptoServiceProvider(cspa); CryptAcquireContext is called to retrieve a context to the default container. If a failure occurs, the smart card will be unusable for smart card sign-in. The name of the container is retrieved by using the PP_CONTAINER parameter with CryptGetProvParam. Call CryptAcquireContext by passing the smart card reader name in as a type II container specification level, and specifying the CRYPT_DEFAULT_CONTAINER_OPTIONAL flag. Call CryptSetProvParam by specifying PP_KEYEXCHANGE_PIN or PP_SIGNATURE_PIN and a null-terminated ASCII PIN. Release the context acquired in Step 1.
if I use: CryptAcquireContext(&hProv, contName ,L" Microsoft Base Smart Card Crypto Provider", PROV_RSA_FULL , flags); it works. But as far as my knowledge goes the Base Smart Card provider is the provider before CNG was introduced.Usage of CRYPT_VERIFYCONTEXT with Smart Cards. (too old to reply) Milton Kuo. 20 years ago. There is a discrepancy between the Platform SDK and the CSPDK in how. CRYPT_VERIFYCONTEXT is used in calls to CryptAcquireContext. Specifically, the PSDK states that pszContainer must be NULL if the CRYPT_VERIFYCONTEXT. flag is set.
