BOOL OW32::CCryptKey::Decrypt (  BYTE *  pbData, DWORD *  cbData, BOOL  bFinal = TRUE, HCRYPTHASH  hHash = NULL, DWORD  dwFlags = 0 )  [inline]

Decrypt data with the given key. Returns: TRUE if successful, FALSE if not Parameters: pbData  The data to decrypt (in/out) cbData  The length of the data to decrypt (in/out) bFinal  TRUE if this is the final block, FALSE if not. hHash  Handle of hash object if hashing at the same time, NULL if not. dwFlags  Flags, if any

BOOL OW32::CCryptKey::Derive (  HCRYPTPROV  hProv, ALG_ID  AlgId, HCRYPTHASH  hBaseData, DWORD  dwFlags = 0 )  [inline]

Derive a key from a hash. Returns: TRUE if successful, FALSE if not. Parameters: hProv  The cryptographic service provider to use. algId  The key algorithm hBaseData  The base data dwFlags  Optional flags for CryptDeriveKey

BOOL OW32::CCryptKey::Encrypt (  BYTE *  pbData, DWORD *  cbData, DWORD  cbBuf, BOOL  bFinal = TRUE, HCRYPTHASH  hHash = NULL, DWORD  dwFlags = 0 )  [inline]

Encrypt data with the given key. Returns: TRUE if successful, FALSE if not Parameters: pbData  The data to encrypt (in/out) cbData  The length of the data to encrypt (in/out) cbBuf  The length of the data buffer (may need to be larger than input data for block ciphers) bFinal  TRUE if this is the final block, FALSE if not. hHash  Handle of hash object if hashing at the same time, NULL if not. dwFlags  Flags, if any

BOOL OW32::CCryptKey::Gen (  HCRYPTPROV  hProv, ALG_ID  AlgId, DWORD  dwFlags = 0 )  [inline]

Generate a new key. Returns: TRUE if successful, FALSE if not. Parameters: hProv  The cryptographic service provider to use. algId  The key algorithm dwFlags  Optional flags for CryptCreateKey

BOOL OW32::CCryptKey::Import (  HCRYPTPROV  hProv, BYTE *  pbData, DWORD  dwDataLen, HCRYPTKEY  hPubKey = 0, DWORD  dwFlags = 0 )  [inline]

Import a key object from existing data. Returns: TRUE if successful, FALSE if not. Parameters: hProv  The cryptographic service provider to use. pbData  The key data dwDataLen  The length of the key data hPubKey  The public key to decrypt the key data with dwFlags  Optional flags for CryptImportKey
