If two hashes match when comparing a downloaded file to the website, what does it indicate?

• A. You can prove the source of the file.
• B. Your copy is the same as the copy posted on the website.
• C. You are the only one able to open the downloaded file.
• D. No one has read the file contents as it was downloaded.

Answer: (B)

When two hashes match during a comparison of a downloaded file with the version posted on a website, it signifies that both the files are identical in content. This matching indicates that the file you downloaded has not been altered or corrupted in any way since it was created, and it matches exactly the file provided by the website. Hash functions create a unique signature for data; hence, if the hash values of both files are the same, it confirms that the byte-for-byte representation of the files is identical. This doesn't necessarily prove the authenticity of the source or guarantee that the file hasn’t been tampered with before it was uploaded to the website. While it suggests the integrity of the file you received, it doesn't provide evidence that it has come from a trusted source or that it hasn’t been compromised at some earlier point. The other statements relate to notions of ownership, access, and content security, which are not directly indicated by just matching hashes.
