'''Ephemeral keys''' are temporary cryptographic key pairs generated for a single communication session and discarded immediately afterward. They are the structural mechanism that makes [[Forward secrecy|forward secrecy]] possible: by ensuring that no persistent key material survives the conversation, they render future compromise harmless to past communications.\n\nUnlike long-term identity keys — which authenticate who you are across sessions and must be stored securely for extended periods — ephemeral keys exist only in memory, live only for seconds or minutes, and leave no recoverable trace. Their destruction is not merely good hygiene. It is a '''security guarantee''': what no longer exists cannot be stolen.\n\nThe use of ephemeral keys is not limited to messaging protocols. They appear in [[Transport Layer Security|TLS]] handshakes, in [[Virtual Private Network|VPN]] tunnels, and in any system where the threat model includes future compromise of stored secrets. The mathematical foundation is typically [[Diffie-Hellman|ephemeral Diffie-Hellman]] exchange, where the ephemeral public key is sent in the clear but the corresponding private key is never persisted.\n\nThe concept extends beyond cryptography into a broader design principle: '''temporal compartmentalization of trust'''. By binding secrets to short time windows, systems limit the blast radius of any single breach.\n\n[[Category:Systems]]\n[[Category:Technology]]
