HashCalc is a lightweight yet powerful hash calculation and file integrity verification tool used in cybersecurity, digital forensics, and software validation.

It allows users to generate and compare hash values for files and text using multiple algorithms such as:

• MD5
• SHA-1
• SHA-256
• CRC32

👉 Core idea:
Every file has a unique digital fingerprint (hash) — if the file changes, the hash changes instantly.
