Privacy and Security Information
A cryptographic hash (like SHA-256) is a one-way mathematical function that maps data of arbitrary size to a fixed-size bit string. It is commonly used to verify file integrity (integrity checks) or securely store passwords. Because this tool runs completely on your local device, you can safely compute hashes for sensitive documents or credential files without exposing them to the internet.
