How to Use the File Hash Tool

To Generate a Hash:

  1. Select the "Generate Hash" tab.
  2. Click to choose a file. You will see a live progress bar as the file is processed.
  3. The MD5, SHA-1, SHA-256, and SHA-512 hashes will be displayed.

To Verify a Hash:

  1. Select the "Verify Hash" tab.
  2. Choose the file and paste the known hash value.
  3. Click "Verify File". The tool will calculate the file's hashes and tell you if it's a match.

Why Check File Hashes?

Verify Downloads

Ensure that a downloaded file (like a software installer) has not been corrupted or tampered with.

Ensure Data Integrity

Confirm that a file has not changed since it was last hashed. This is critical for backups and digital forensics.

Understanding Hash Algorithms

  • MD5: A fast and widely used algorithm, primarily for checking for unintentional file corruption. It is no longer considered secure for cryptography.
  • SHA-1: Similar to MD5 but stronger. Also considered insecure for cryptographic purposes but still common for file integrity checks.
  • SHA-256 / SHA-512: Modern, secure standards developed by the NSA. SHA-256 is the most common standard for security applications today.
