🛡️

Part of the SHA-2 family. It remains extremely secure and is widely used in Blockchain (Bitcoin), TLS/SSL, and software signing.

💎

Similar to SHA-256 but operates on 64-bit words, making it faster on 64-bit systems and significantly more resistant to brute force.

⚠️

A legacy algorithm with known collision vulnerabilities. Useful for checksums and file verification, but unsafe for security.
