Is SHA-256 still secure?

Yes. SHA-256 is part of the SHA-2 family and is considered secure for all current applications. It is widely used in TLS certificates, blockchain and digital signatures.

What is the difference between SHA-256 and SHA-512?

SHA-256 produces a 256-bit (32-byte) hash while SHA-512 produces a 512-bit (64-byte) hash. SHA-512 offers a larger security margin but SHA-256 is sufficient for virtually all use cases.
