- A green checkmark or red X shows whether the hashes match.
Frequently Asked Questions
How do I verify a downloaded file?
Download the file and the expected hash from the source website. Drop the file here, paste the expected hash, and if they match the file is intact.
Which hash algorithms are supported?
SHA-256, SHA-512, and MD5. Use SHA-256 or SHA-512 for security-critical verification; MD5 only for legacy systems.
What does it mean if the hashes do not match?
The content is different from what was expected. This could mean the file was corrupted during download, or in the worst case, tampered with.
