to generate key:-

                openssl genrsa 1024 > key



to generate certificate:-

                        openssl req -new -x509 -nodes -sha1 -days 365 -key key > cert











OpenSSL also provides a test SSL client/server in the style of telnet/netcat, great for debugging:



openssl s_server -accept 12345 -cert cert -key key

openssl s_client -connect localhost:12345
