You can encrypt using Public key BUT ONLY DECRYPT USING PRIVATE KEY. Now I want to mention the Asymmetric Encryption. Them your web browser (or anything else) can encrypt data using Public Key (That anyone can know) and sends it to server. When you are connecting to the it first sends you it's certificate and also public key. If client and server would communicate in plain text then anyone could see what is going in the connection and make date change on it's way. You have to understand what make connection secure. server/certs/server.crtĬA/server/certs: type server.crt. !IMPORTANT: Edit in sub-ca/nf and change DNS names to that are needed because borwers ignore CN.ĬA/sub-ca: openssl ca -config nf -extensions server_cert -days 1825 -notext -in. # Sign server certificate signing request # Create csr for server using server's private keyĬA/server: openssl req -key private/server.key -new -sha256 -out csr/server.csr sub-ca/certs/sub-ca.crtĬA/root-ca: openssl x509 -noout -text -in. # Creating Signing Request for Inerminade CertificateĬA/sub-ca: openssl req -config nf -new -key private/sub-ca.key -sha256 -out csr/sub-ca.csrĬA/root-ca: openssl ca -config nf -extensions v3_intermediate_ca -days 3650 -notext -in.

I preformed it on windows but you should be fine on linux too.
#Python3 scapy check if a client hello tls packet install
PS Please install OpenSSL and then follow the instruction, also

I made it when I still was learning english. Sorry for it being a little bit messy and some typing errors but Generate a Root CA, Sub CA and Certificate for server Know what is that read yourself something about asymmetricĬryptology).
