Jak funguje¶

Standardní TLS: klient ověřuje server. mTLS: obě strany.

Certifikáty¶

CA¶

openssl req -x509 -nodes -days 3650 -newkey rsa:4096 -keyout ca.key -out ca.crt -subj ‘/CN=MyCA’

Server¶

openssl req -nodes -newkey rsa:2048 -keyout server.key -out server.csr -subj ‘/CN=server’ openssl x509 -req -in server.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out server.crt

Client¶

openssl req -nodes -newkey rsa:2048 -keyout client.key -out client.csr -subj ‘/CN=client’ openssl x509 -req -in client.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out client.crt

Nginx¶

ssl_client_certificate /etc/ssl/ca.crt; ssl_verify_client on;

curl¶

curl –cert client.crt –key client.key –cacert ca.crt https://api.example.com

mTLS = Zero Trust¶

V service mesh je automatický. Pro vlastní služby interní CA.
