RS256

RS256 is a type of digital signature used to verify the authenticity of data, especially in secure communications like online logins. It combines two key ideas: encryption with a private key (known only to the owner) to sign the data, and decryption with a public key (shared openly) to verify the signature. This ensures that the data hasn’t been altered and that it genuinely comes from the expected sender. Think of it like a digital fingerprint: only the owner can create the signature, but anyone with the public key can verify it.
