Recommendation: Use SHA-256 for Most Applications

SHA-256 offers the best balance of security and performance. It's the industry standard used in Bitcoin, SSL certificates, and most security applications. Only use SHA-512 when you need extra security margin or SHA-384 for specific compliance requirements.
