A matching cryptographic checksum shows that a file matches the reference value used for comparison. Its usefulness depends on obtaining that reference through a trustworthy independent route. A hash does not by itself establish that the publisher is legitimate or that the software behaves safely.
Compare the same algorithm and file
A SHA-256 value should be compared with another SHA-256 value for the exact package and version. A different operating-system build will normally have a different hash. Renaming a file does not change its contents, but downloading a different package does.
Protect the reference channel
If an attacker can replace both the installer and the checksum on the same untrusted page, the comparison provides little reassurance about origin. Prefer publisher documentation, signed release information or another verifiable channel rather than a copied value in an anonymous comment.
Keep integrity and trust separate
A correct hash can help detect an incomplete or altered download relative to a known file. It does not review permissions, privacy behaviour or compatibility. Continue to inspect publisher identity and operating-system warnings before installation.
