The Fixity service will verify the bit-level integrity of files managed by the Storage service. File integrity is evaluated by first calculating a message digest for the file. These can take many forms, such as MD5, CRC-32, or SHA-1. This calculated message digest is then compared with one supplied or created at the time of ingest into a curation environment. If the file has been somehow corrupted, these two message digests will not match, which will signal the repository manager to intervene.
