Explanation
The web of trust is a decentralized approach used in public key cryptography. In this system, users validate the authenticity of each other's public keys by digitally signing them. When a user trusts another user's key and signs it with their own key, they effectively vouch for the authenticity of the other user's key. This creates a network of trust where the validity of a public key can be established based on the endorsements and signatures of other users within the network. It allows users to build trust in keys even without a central authority, enhancing the security and trustworthiness of exchanged public keys.
