Some software vendors publish MD5 sums for their downloads.
Example:
“Verified MD5: 5d073e0e786b40dfb83623cf053f8aaf for setup_v2.3.exe” 5d073e0e786b40dfb83623cf053f8aaf verified
If you have a file, you can compute its MD5 and compare: Some software vendors publish MD5 sums for their downloads
# Linux/macOS md5sum yourfileCertUtil -hashfile data.bin MD5or
Get-FileHash data.bin -Algorithm MD5
certutil -hashfile yourfile MD5
If they match, the file is verified as identical to the original source. If you have a file, you can compute
