sesjonsciphernøkler
A sesjonsciphernøkkel, often translated as session encryption key, is a temporary cryptographic key used to encrypt and decrypt a communication session. Unlike a long-term master key, a sesjonsciphernøkkel is generated for a specific, limited period of time or for a single transaction. This approach significantly enhances security by minimizing the impact of a key compromise. If a sesjonsciphernøkkel is stolen or broken, only that particular session's data is exposed, leaving other communications and master keys secure.
The process typically involves a key exchange protocol, such as Diffie-Hellman, where two parties securely agree
