SHA-256 Guidelines

Cryptographic Security: SHA-256 (Secure Hash Algorithm 256-bit) produces a unique 256-bit (32-byte) signature represented as a 64-character hexadecimal string.
Integrity Verification: Commonly used to verify downloaded software binaries, firmware images, and package integrity against official vendor hashes.
Client-Side Processing: All hashing operations execute locally within your browser using the Web Crypto API (`crypto.subtle`). Files never leave your device.
