Before running utility software downloaded from the internet, it is critical to verify its cryptographic hash. This ensures the binary exactly matches the original author's release and has not been tampered with.
Press the Windows Key, type PowerShell, and press Enter.
By default, PowerShell's Get-FileHash command computes the SHA-256 hash. Run the following command, replacing the path with the location of your downloaded TFC.exe file:
Get-FileHash -Path "C:\Users\YourName\Downloads\TFC.exe"
To check the MD5 hash, append the -Algorithm MD5 flag:
Get-FileHash -Path "C:\Users\YourName\Downloads\TFC.exe" -Algorithm MD5
Examine the output returned by PowerShell. The hash string must match the authentic hashes provided above identically. If the hashes differ, delete the downloaded file immediately.
