The first part looks like a complete signature in DER format. If it matches the transaction and public key, could be valid.

The second string seems like a public key in hex.

But just eyeballing here – real validation happens when the Bitcoin network checks 'em out. Gotta put it through the crypto wringer! 🔄🔒👨‍💻

That's not a signature, it's a scriptPubKey for a P2PKH address. It tells you how to spend the coins, like needing the right sig and pubkey.

The real sig pops up when someone tries to spend those coins. That's when we see if it's valid or not! 🔑📜✅
