# ImageGetDigestStream(3w)

## NAME

**ImageGetDigestStream** (IMAGEHLP.@)

## SYNOPSIS

BOOL ImageGetDigestStream\
  (\
   HANDLE          *FileHandle*,\
   DWORD           *DigestLevel*,\
   DIGEST\_FUNCTION *DigestFunction*,\
   DIGEST\_HANDLE   *DigestHandle*\
  )

## DESCRIPTION

Gets a stream of bytes from a **PE** file over which a hash might be computed to verify that the image has not changed. Useful for creating a certificate to be added to the file with ImageAddCertificate.

## PARAMS

*FileHandle* **\[In\]**  File for which to return a stream.

*DigestLevel* **\[In\]**  Flags to control which portions of the file to return. **0** is allowed, as is any combination of: CERT\_PE\_IMAGE\_DIGEST\_ALL\_IMPORT\_INFO: reports the entire import section rather than selected portions of it. CERT\_PE\_IMAGE\_DIGEST\_DEBUG\_INFO: reports the debug section. CERT\_PE\_IMAGE\_DIGEST\_RESOURCES: reports the resources section.

*DigestFunction* **\[In\]**  Callback function.

*DigestHandle* **\[In\]**  Handle passed as first parameter to *DigestFunction*.

## RETURNS

**TRUE** if successful. **FALSE** if unsuccessful. GetLastError returns more about the error.

## NOTES

Only supports **32**-bit **PE** files, not tested with any other format. Reports data in the following order: 1. The file headers are reported first 2. Any code sections are reported next. 3. The data (**".data"** and **".rdata"**) sections are reported next. 4. The import section is reported next. 5. If **CERT\_PE\_IMAGE\_DIGEST\_DEBUG\_INFO** is set in *DigestLevel*, the debug section is reported next. 6. If **CERT\_PE\_IMAGE\_DIGEST\_RESOURCES** is set in *DigestLevel*, the resources section is reported next.

## BUGS

**CERT\_PE\_IMAGE\_DIGEST\_ALL\_IMPORT\_INFO** must be specified, returns an error if not.

## IMPLEMENTATION

Declared in **"imagehlp.h"**.

Implemented in **"dlls/imagehlp/integrity.c"**.
