For Base Providers, this means that user key containers are stored in the user's profile. These keys must be created as a separate step with the CryptGenKey function. Cryptacquirecontexta

A context can be acquired by using the CRYPT_VERIFYCONTEXT flag if you only plan to import the public key.

Here is the code we were using:   ‘Get handle to CSP  If (CryptAcquireContext(hCryptProv, KEY_CONTAINER, SERVICE_PROVIDER, PROV_RSA_FULL, CRYPT_MACHINE_KEYSET) = 0) Then    If (CryptAcquireContext(hCryptProv, KEY_CONTAINER, SERVICE_PROVIDER, PROV_RSA_FULL, CRYPT_MACHINE_KEYSET + CRYPT_NEWKEYSET) = 0) check my blog i've had problems using this in a VB component from an ASP page on a Win2K machine (permissions), but i found a great pure VB algorithm that works really well.

With the appropriate setting of dwFlags, this function can also create and destroy key containers and can provide access to a CSP with a temporary key container if access to a Prov_rsa_full if(!CryptContextAddRef( hCryptProv, NULL, 0)) { HandleError("Error during CryptContextAddRef!\n"); } printf("CryptContextAddRef succeeded. \n"); // hCryptProv 1. // CryptReleaseContext . // This is a null-terminated string that identifies the key container to the CSP.

If you plan to perform private key operations, the best way to acquire a context is to try to open the container.

A subsequent call to try creating the same container verifies that assumption because I get the win32 error that the keyset is already defined. Each container can contain one key. NTE_PROV_TYPE_NO_MATCH 0x8009001BL The provider type specified by dwProvType does not match the provider type found. Crypt_verifycontext First of all, it continuously tells the encryption data passed would be the final one.

To create a key container, call CryptAcquireContext using the CRYPT_NEWKEYSET flag. Browse other questions tagged c# .net cryptoapi or ask your own question. This form is used to connect to the CSP to query its capabilities but not to actually use its keys. news Join them; it only takes a minute: Sign up CryptoAPI AcquireContext fails to retrieve key container up vote 2 down vote favorite I am porting an old vb6 application to .net

Some possible error codes defined in Winerror.h follow. Delete a key container by using the CryptAcquireContext function. This error code can also indicate that access to an existing key container is denied. But why reinvent the wheel?

The second call was sending an error of -2146893809.
