How to Verify SHA256 Checksum (Step-by-Step Guide)
Verifying a SHA256 checksum is essential to ensure that a file has not been modified or corrupted. In this guide, you’ll learn how to check a SHA256 hash easily using different methods.
What is a SHA256 checksum?
A SHA256 checksum is a unique hash generated from a file using the SHA256 algorithm. It acts like a digital fingerprint to verify file integrity.
Why verify a SHA256 checksum?
- Ensure file integrity
- Detect tampering or corruption
- Verify downloads
- Improve security
How to verify SHA256 checksum (Windows)
CertUtil -hashfile filename.zip SHA256
Compare the output with the original hash provided by the source.
How to verify SHA256 checksum (Mac & Linux)
shasum -a 256 filename.zip
Make sure both hashes match exactly.
