The most effective way to verify that a downloaded file is exactly what it claims to be is to check its cryptographic hash, also known as a checksum. A checksum is a unique alphanumeric string generated by running a file through a hashing algorithm (like MD5 or SHA-256). If a single byte in the file changes, its entire checksum will change. By comparing the checksum of a file you download against a known good checksum from a trusted source, you can confirm the file's authenticity.
