# RSAENH\_CPGetHashParam(3w)

## NAME

**RSAENH\_CPGetHashParam** (RSAENH.@)

## SYNOPSIS

BOOL RSAENH\_CPGetHashParam\
  (\
   HCRYPTPROV *hProv*,\
   HCRYPTHASH *hHash*,\
   DWORD      *dwParam*,\
   BYTE\*      *pbData*,\
   DWORD\*     *pdwDataLen*,\
   DWORD      *dwFlags*\
  )

## DESCRIPTION

Query parameters of an hash object.

## PARAMS

*hProv* **\[In\]**  The kea container, which the hash belongs to.

*hHash* **\[In\]**  The hash object that is to be queried.

*dwParam* **\[In\]**  Specifies the parameter that is to be queried.

*pbData* **\[In\]**  Pointer to the buffer where the parameter value will be stored.

*pdwDataLen* **\[In/Out\]**  I: Buffer length at *pbData*, O: Length of the parameter value.

*dwFlags* **\[In\]**  None currently defined.

## RETURNS

**Success:** **TRUE**

**Failure:** **FALSE**.

## NOTES

Valid dwParams are: **HP\_ALGID**, **HP\_HASHSIZE**, **HP\_HASHVALUE**. The hash will be finalized if **HP\_HASHVALUE** is queried.

## IMPLEMENTATION

Not declared in a Wine header. The function is either undocumented, or missing from Wine.

Implemented in **"dlls/rsaenh/rsaenh.c"**.

Debug channel **"crypt"**.
