Abstract
For a source file on which basis a binary object file has been generated, a digital signature is generated for the source file, and the digital signature is stored. The digital signature may be secure hash algorithm (SHA) hash values. The binary object file is output. To verify that the binary object file has been generated from the source file, a digital signature is generated for the source file, and compared to the digital signature for the source file as previously stored. Where the digital signature for the source file as has been generated matches the digital signature for the source file previously stored, the binary object file is indicated as having been generated from the source file.
