File Fingerprint
A cryptographic hash value computed over file contents, such as SHA-256, used to uniquely identify a specific file version. Any byte-level change produces a completely different digest, making it a core verification mechanism in code evidence chains.
Timeline (last 90 days)
File fingerprints (such as SHA-256 checksums) are used to uniquely identify file contents; as long as the file contents change in any way, the fingerprint will differ.
In the demonstration, by computing the JAR's fingerprint and verifying the running file's fingerprint after deployment, it was confirmed that the running service used the package built in this run, rather than an old version or a cached file.
A file fingerprint usually refers to a cryptographic hash computed over the file contents (such as SHA-256), and any byte-level change produces a completely different digest.
A fingerprint only covers the files explicitly included in the computation; untracked dependencies, generated artifacts, or external resources are not automatically included.
A source file fingerprint cannot prove everything about the code's runtime environment; environment dependencies, system library versions, and configuration differences are not covered by the source file fingerprint.
