What's the difference between SHA-512 and SHA-256?
SHA-512 outputs 512 bits (128 hex chars), SHA-256 outputs 256 bits (64 chars). SHA-512 offers higher security and collision resistance but requires more computation. On 64-bit systems, SHA-512 is often faster than SHA-256. Used for password storage, digital signatures, and blockchain applications needing top security.
Does it work on mobile?
Yes. Responsive design works on phones, tablets, and desktops.
