FAQ: Checksum Generator/Verifier
What is the difference between SHA-256 and SHA-512?
Both are secure hashes; SHA-512 has longer output and can be preferred in stricter policies.
Can I verify checksum files from Linux distributions?
Yes. Standard hash-first manifest formats are supported for quick verification.
Does checksum verification replace signature verification?
No. Signatures confirm publisher authenticity, while checksums confirm file integrity.
