-Routine Description:
-
- Signs the section with CRC32 and add GUIDed section header for the
- signed data. data stays in same location (overwrites source data).
-
-Arguments:
-
- FileBuffer - Buffer containing data to sign
-
- BufferSize - On input, the size of FileBuffer. On output, the size of
- actual section data (including added section header).
-
- DataSize - Length of data to Sign
-
- Key - Key to use when signing. Currently only CRC32 is supported.
-
-Returns:
-
- EFI_SUCCESS - Successful
- EFI_OUT_OF_RESOURCES - Not enough resource to complete the operation.
