Update makefiles so that consistent patterns are used. Object files are compiled from source using an implicit rule (but using our CFLAGS); for linking, we give an explicit rule. Ensure that "make test" works in each subdirectory (even if it does not actually run any applications). The top-level demo makefile now works. The makefiles are not make-agnostic. e.g. they use the variable $(RM) in "clean" recipes, which is defined in gnu-make but may not be defined in others.

The OpenSSL Guide Demos
The demos in this directory are the complete source code for the applications developed in the OpenSSL Guide tutorials. Refer to the various tutorial pages in the guide for an extensive discussion on the demos available here.
They must be built before they can be run. An example UNIX style Makefile is supplied. Just type "make" from this directory on a Linux/UNIX system.
Running the TLS Demos
To run the demos when linked with a shared library (default) ensure that libcrypto and libssl are on the library path. For example, assuming you have already built OpenSSL from this source and in the default location then to run the tls-client-block demo do this:
LD_LIBRARY_PATH=../.. ./tls-client-block hostname port
In the above replace "hostname" and "port" with the hostname and the port number of the server you are connecting to.
The above assumes that your default trusted certificate store containing trusted CA certificates has been properly setup and configured as described on the TLS Introduction page.
You can run a test server to try out these demos using the "openssl s_server" command line utility and using the test server certificate and key provided in this directory. For example:
LD_LIBRARY_PATH=../.. ../../apps/openssl s_server -www -accept localhost:4443 -cert servercert.pem -key serverkey.pem
The test server certificate in this directory will use a CA that will not be in your default trusted certificate store. The CA certificate to use is also available in this directory. To use it you can override the default trusted certificate store like this:
SSL_CERT_FILE=rootcert.pem LD_LIBRARY_PATH=../.. ./tls-client-block localhost 4443
If the above command is successful it will connect to the test "s_server" and send a simple HTTP request to it. The server will respond with a page of information giving details about the TLS connection that was used.
Note that the test server certificate used here is only suitable for use on "localhost".
The tls-client-non-block demo can be run in exactly the same way. Just replace "tls-client-block" in the above example commands with "tls-client-non-block".
Running the QUIC Demos
The QUIC demos can be run in a very similar way to the TLS demos. However, a different server implementation will need to be used.
The OpenSSL source distribution includes a test QUIC server implementation for use with the demos. Note that, although this server does get built when building OpenSSL from source, it does not get installed via "make install". After building OpenSSL from source you will find the "quicserver" utility in the "util" sub-directory of the top of the build tree. This server utility is not suitable for production use and exists for test purposes only. It will be removed from a future version of OpenSSL.
While in the demos directory the quic server can be run like this:
./../util/quicserver localhost 4443 servercert.pem serverkey.pem
The QUIC demos can then be run in the same was as the TLS demos. For example to run the quic-client-block demo:
SSL_CERT_FILE=rootcert.pem LD_LIBRARY_PATH=../.. ./quic-client-block localhost 4443
