Error During Cryptacquirecontext New Key Container

Contents

Windows XP:  The key container created with CRYPT_MACHINE_KEYSET by an administrator can be accessed only by its creator and by the local system account unless access rights to the container are granted using In most cases, when dwFlags is set to CRYPT_VERIFYCONTEXT, pszContainer must be set to NULL. In particular I can't retrieve a key container which is already defined. NTE_BAD_FLAGS 0x80090009L The dwFlags parameter has a value that is not valid. this content

If this parameter is NULL, the user default provider is used. The second attempts to create a new container if it cannot find the existing key container. To acquire the context and the key container of a private key associated with the public key of a certificate, use CryptAcquireCertificatePrivateKey.

Error During Cryptacquirecontext New Key Container

I just installed my licensed application on a Windows Embedded system (WinXP - WePos) and when during licensing, it throws the following error (in dialog box): "1159: DLL error code shown You are deriving a symmetric key from a hash to encrypt or decrypt data. For extended error information, call GetLastError. The default CSP can change between operating system releases.

  • For more information about the usage of the pszContainer parameter, see Remarks.
  • This example uses the function MyHandleError.
  • By default, keys and key containers are stored as user keys.
  • cbData = MAX_CONTAINER_NAME_LEN; if(!CryptGetProvParam( hCryptProv, PP_CONTAINER, pbData, &cbData, 0)) { HandleError("Error reading key container name. \n"); } if(cbData > MAX_CONTAINER_NAME_LEN) HandleError("Container name length is too long"); if(!CryptGetProvParam( hCryptProv, PP_CONTAINER, pbData, &cbData,

Go to C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\3. A key container created without this flag by a user that is not an administrator can be accessed only by the user creating the key container and the local system account. if(!CryptContextAddRef( hCryptProv, NULL, 0)) { HandleError("Error during CryptContextAddRef!\n"); } printf("CryptContextAddRef succeeded. \n"); // hCryptProv 1. // CryptReleaseContext . // Cryptacquirecontext Nte_bad_keyset To ensure interoperability on different operating system platforms, the CSP should be explicitly set by using this parameter instead of using the default CSP.

For more information, see Cryptographic Service Provider Contexts. If no default key container exists, use the CryptAcquireContext function to create the default key container.

If you specify the name of an existing container when creating keys, the new key will overwrite a previous one. So we reinstalled the web application, uninstalled and reinstalled the COM dlls as well as some system dlls.

A context can be acquired by using the CRYPT_VERIFYCONTEXT flag if you only plan to import the public key. Crypt_verifycontext If you plan to perform private key operations, the best way to acquire a context is to try to open the container.

See ASP.NET Ajax CDN Terms of Use – http://www.asp.net/ajaxlibrary/CDN.ashx. ]]> Developer resources Microsoft developer Windows Windows Dev Center Windows Obviously, something is missing/different. CRYPT_NEWKEYSET Creates a new key container with the name specified by pszContainer. You are performing private key operations, but you are not using a persisted private key that is stored in a key container.

For Base Providers, this means that user key containers are stored in the user's profile. if(!CryptAcquireContext( &hCryptProv, "KC1_test", NULL, PROV_GOST_2001_DH, 0)) { HandleError("Error during CryptAcquireContext!\n"); } printf("Acquired the key set just created. \n"); // . // KC1.

When this flag is set, temporary public/private key pairs can be created, but they are not persisted. Browse other questions tagged c# .net cryptoapi or ask your own question.

Anyways, during a routine security patch deployment the encryption dll on one of the servers stopped working. The combination of the CSP name and the key container name uniquely identifies a single key on the system. We appreciate your feedback. The first call was giving me an error of -2146893802.
