Decrypts a data buffer using the key associated with the cryptography object.
HRESULT
__stdcall Decrypt(
__in PINFORMATIONCARD_CRYPTO_HANDLE hCrypto,
__in BOOL fOAEP,
__in DWORD cbInData,
__in_bcount( cbInData ) PBYTE pInData,
__out DWORD *pcbOutData,
__out_bcount( *pcbOutData ) PBYTE* ppOutData );
Parameters
| Parameter | Description |
|---|---|
hCrypto |
Handle to the cryptography object associated with a previously released security token. |
fOAEP |
If false, Public-Key Cryptography Standards (PKCS1) v1.5 padding is stripped from the decrypted data. If true, PKCS1 v2 is stripped from the decrypted data. |
cbInData |
The length, in bytes, of the input buffer. |
pInData |
The data to be decrypted. |
pcbOutData |
The length, in bytes, of the output buffer. |
ppOutData |
The output buffer in which to put the decrypted data. When you have finished using this buffer, free it using the Win32 GlobalFree function. |
Property Value/Return Value
HRESULT: If any of the parameters are NULL or 0, E_INVALIDARG is returned. If the buffer is NULL, then E_OUTOFMEMORY is returned.
