Pads and signs a buffer that contains a hash using Public-Key Cryptography Standards (PKCS1).
HRESULT
__stdcall SignHash(
__in PINFORMATIONCARD_CRYPTO_HANDLE hCrypto,
__in DWORD cbHash,
__in_bcount( cbHash ) PBYTE pHash,
__in LPCWSTR hashAlgOid,
__out DWORD* pcbSig,
__out_bcount( *pcbSig ) PBYTE* ppSig );
Parameters
| Parameter | Description |
|---|---|
hCrypto |
Handle to the cryptography object associated with a previously released security token. |
cbHash |
The length, in bytes, for both the input and output buffers. |
pHash |
The data to be decrypted. |
hashAlgOid |
The string OID that identifies the hash algorithm used to produce the data to be decrypted in pHash. The supported values for hashAlgOid are the OIDs for MD5 or SHA1. |
pcbSig |
The length of the returned signature. |
ppSig |
A pointer to a buffer that contains the returned signature. When you have finished using this pointer, free the memory by using the Win32 GlobalFree function. |
Property Value/Return Value
HRESULT: If any of the parameters are NULL or 0, E_INVALIDARG is returned.
