# Application File Integrity Verification When downloading files related to applications, it is important to ensure their integrity. Verifying the SHA256 checksum helps confirm that the file has not been corrupted during the download process. ## Steps to Verify SHA256 Checksum 1. Note the SHA256 value mentioned on the download page. 2. Navigate to the directory where the downloaded file is located. 3. Open the Command Prompt with Administrator privileges and execute the appropriate command based on your operating system, as shown below. **Note:** Replace the *\* with the actual file name. - **MAC OS X** ```bash shasum -a 256 ``` - **Windows** ```bash CertUtil -hashfile SHA256 ``` - **Linux** ```bash sha256sum ``` - **FreeBSD** ```bash sha256 ``` 4. After executing the command, verify that the returned checksum value matches the SHA256 value provided on the respective download page. If the values do not match, download the file again and repeat the procedure.
