TLSklientsertifikater

TLSklientsertifikater, also known as TLS client certificates, are digital certificates used to authenticate a client attempting to connect to a server. They are a key component of the Transport Layer Security (TLS) protocol, a cryptographic protocol designed to provide communications security over a computer network. Unlike server certificates which identify the server to the client, client certificates verify the identity of the client to the server.

During the TLS handshake process, if client authentication is enabled, the server will request a client certificate. The client then presents its certificate, along with the corresponding private key, to prove its identity. This process adds an extra layer of security beyond just username and password authentication. It ensures that only authorized and specifically identified clients can access the protected resources.

TLSklientsertifikater are particularly useful in scenarios requiring strong authentication, such as corporate networks, secure access to sensitive data, or for business-to-business (B2B) transactions. They help prevent unauthorized access and mitigate risks associated with compromised credentials. The issuance and management of these certificates are typically handled by a trusted Certificate Authority (CA).
