The chain ensures that the authenticity and integrity of the public key can be verified by anyone who trusts the root CA.
The chain typically consists of three parts: the end‑entity certificate (the server or client), one or more
During a TLS handshake, a server presents its sertifikatkjede. The client verifies each certificate by checking
In blockchain and smart‑contract systems, a variant of the sertifikatkjede is used to certify the authenticity
Overall, the sertifikatkjede is a foundational component of Public Key Infrastructure. It enables secure communication, authentication,
