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.
