NAME

CryptUnprotectData (CRYPT32.@)

SYNOPSIS

 BOOL CryptUnprotectData
 (
  DATA_BLOB*                 pDataIn,
  LPWSTR*                    ppszDataDescr,
  DATA_BLOB*                 pOptionalEntropy,
  PVOID                      pvReserved,
  CRYPTPROTECT_PROMPTSTRUCT* pPromptStruct,
  DWORD                      dwFlags,
  DATA_BLOB*                 pDataOut
 )

DESCRIPTION

Generate Plain data and Description from given Cipher and Entropy data.

PARAMS

`pDataIn`	[In]	Cipher data to be decoded.
`ppszDataDescr`	[Out]	Optional Unicode string describing the Plain data.
`pOptionalEntropy`	[In]	Optional entropy data to adjust cipher, can be `NULL`.
`pvReserved`	[In]	Reserved, must be `NULL`.
`pPromptStruct`	[In]	Structure describing if/how to prompt during decoding.
`dwFlags`	[In]	Flags describing options to the decoding.
`pDataOut`	[Out]	Resulting Plain data, from calls to CryptProtectData.

RETURNS

TRUE If a Plain was generated. FALSE If something failed and no Plain is available.

FIXME

The TRUE Windows® encryption and keying mechanisms are unknown.

dwFlags and pPromptStruct are currently ignored.

NOTES

Memory allocated in pDataOut and non-NULL ppszDataDescr must be freed with LocalFree.
