1The OpenSSL Guide Demos 2======================= 3 4The demos in this directory are the complete source code for the applications 5developed in the OpenSSL Guide tutorials. Refer to the various tutorial pages in 6the [guide] for an extensive discussion on the demos available here. 7 8They must be built before they can be run. An example UNIX style Makefile is 9supplied. Just type "make" from this directory on a Linux/UNIX system. 10 11Running the TLS Demos 12--------------------- 13 14To run the demos when linked with a shared library (default) ensure that 15libcrypto and libssl are on the library path. For example, assuming you have 16already built OpenSSL from this source and in the default location then to run 17the tls-client-block demo do this: 18 19LD_LIBRARY_PATH=../.. ./tls-client-block hostname port 20 21In the above replace "hostname" and "port" with the hostname and the port number 22of the server you are connecting to. 23 24The above assumes that your default trusted certificate store containing trusted 25CA certificates has been properly setup and configured as described on the 26[TLS Introduction] page. 27 28You can run a test server to try out these demos using the "openssl s_server" 29command line utility and using the test server certificate and key provided in 30this directory. For example: 31 32LD_LIBRARY_PATH=../.. ../../apps/openssl s_server -www -accept localhost:4443 -cert servercert.pem -key serverkey.pem 33 34The test server certificate in this directory will use a CA that will not be in 35your default trusted certificate store. The CA certificate to use is also 36available in this directory. To use it you can override the default trusted 37certificate store like this: 38 39SSL_CERT_FILE=rootcert.pem LD_LIBRARY_PATH=../.. ./tls-client-block localhost 4443 40 41If the above command is successful it will connect to the test "s_server" and 42send a simple HTTP request to it. The server will respond with a page of 43information giving details about the TLS connection that was used. 44 45Note that the test server certificate used here is only suitable for use on 46"localhost". 47 48The tls-client-non-block demo can be run in exactly the same way. Just replace 49"tls-client-block" in the above example commands with "tls-client-non-block". 50 51Running the QUIC Demos 52---------------------- 53 54The QUIC demos can be run in a very similar way to the TLS demos. However, a 55different server implementation will need to be used. 56 57The OpenSSL source distribution includes a test QUIC server implementation for 58use with the demos. Note that, although this server does get built when building 59OpenSSL from source, it does not get installed via "make install". After 60building OpenSSL from source you will find the "quicserver" utility in the 61"util" sub-directory of the top of the build tree. This server utility is not 62suitable for production use and exists for test purposes only. It will be 63removed from a future version of OpenSSL. 64 65While in the demos directory the quic server can be run like this: 66 67./../util/quicserver localhost 4443 servercert.pem serverkey.pem 68 69The QUIC demos can then be run in the same was as the TLS demos. For example 70to run the quic-client-block demo: 71 72SSL_CERT_FILE=rootcert.pem LD_LIBRARY_PATH=../.. ./quic-client-block localhost 4443 73 74<!-- Links --> 75 76[guide]: https://www.openssl.org/docs/manmaster/man7/ossl-guide-introduction.html 77[TLS Introduction]: https://www.openssl.org/docs/manmaster/man7/ossl-guide-tls-introduction.html 78
