CARD_RSA_DECRYPT_INFO structure
This topic is not current. For the most current information about the Smart Card API, see Smart Card Minidriver Specification.
The CARD_RSA_DECRYPT_INFO structure specifies the data to be decrypted by the CardRSADecrypt function as well as the private key used to perform the decryption.
Syntax
typedef struct _CARD_RSA_DECRYPT_INFO {
DWORD dwVersion;
BYTE bContainerIndex;
DWORD dwKeySpec;
PBYTE pbData;
DWORD cbData;
} CARD_RSA_DECRYPT_INFO, *PCARD_RSA_DECRYPT_INFO;
Members
-
dwVersion
-
The version number of the structure.
-
bContainerIndex
-
The key container index number. The container holds the keys that perform the decryption.
-
dwKeySpec
-
The purpose of the keys in the new container. This member can be one of the following values.
Value Meaning - AT_KEYEXCHANGE
- 1
The keys are used to encrypt and decrypt session keys. - AT_SIGNATURE
- 2
The keys are used to create and verify digital signatures. -
pbData
-
A pointer to an array of decrypted data values. On input, the array specifies the data to be decrypted. On output, the array specifies the decrypted data.
-
cbData
-
The length, in bytes, of the decrypted data pointed to by the pbData member. This value must always be the same as the key modulus.
