+# Generating SSL certificates
+
+## Java keytool way (recommended)
+
+To generate:
+
+```shell
+./gen-certs.sh
+```
+
+To clean (remove generated files):
+
+```shell
+./gen-certs.sh clean
+```
+
+## OpenSSL way (currently might not work)
+
+> Add `-f Makefile-openssl` to each command
+
+Typical usage:
+
+```shell
+make FILE=client
+make FILE=server
+```
+
+or (to generate PKCS12 key and trust stores):
+
+```shell
+make create-key-store FILE=client
+make create-key-store FILE=server
+make create-trust-store
+```
+
+Will generate CA certificate and signed client and server certificates.
+
+More "low-level" usage:
+
+```shell
+make generate-ca-certificate
+make generate-private-key FILE=client 
+make sign FILE=client
+```
+
+# Connecting to a server
+
+First generate *client* and *server* certificates. Then start a server with it's cert and make ca.crt a trusted certification authority.
+
+After that you can:
+
+```shell
+./connect.sh client localhost:8600 < file_with_a_data_to_be_sent.dat
+```
