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