CARD_RSA_DECRYPT_INFO Structure

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.
