What is a file hash?
A hash is a unique fingerprint for a file. If even one byte changes, the hash will be completely different. This makes hashes useful for verifying that a file has not been modified or corrupted.
Why verify downloaded files?
Verifying ensures the file you downloaded is exactly what the seller uploaded. This protects against corrupted downloads and confirms authenticity.
