How to Generate Certificates and Keys for mTLS

# CA cert
openssl genrsa -out ca.key 2048
openssl req -x509 -new -nodes -key ca.key -sha256 -days 3650 -out ca.crt -subj "/CN=Test CA"

# server cert and key
openssl genrsa -out server.key 2048
openssl req -new -key server.key -out server.csr -subj "/CN=localhost"
openssl x509 -req -in server.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out server.crt -days 365 -sha256

# client cert and key
openssl genrsa -out client.key 2048
openssl req -new -key client.key -out client.csr -subj "/CN=client"
openssl x509 -req -in client.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out client.crt -days 365 -sha256
