<div tiddler="Read Me" modifier="YourName" modified="200804011313" created="200702240020" tags="">!@@bgcolor(#ff0000):color(#ffffff):axTLS Quick Start Guide@@\n\nThis is a guide to get a small SSL web-server up and running quickly.\n\n!!__Introduction__\n\nThe axTLS project is an SSL client/server library using the ~TLSv1 protocol. It is designed to be small and fast, and is suited to embedded projects. A web server is included.\n\nThe basic web server + SSL library is around 60-70kB and is configurable for features or size.\n\n!!__Compilation__\n\nAll platforms require GNU make. This means on Win32 that Cygwin needs to be installed with &quot;make&quot; and various developer options selected.\n\nConfiguration now uses a tool called &quot;mconf&quot; which gives a nice way to configure options (similar to what is used in ~BusyBox and the Linux kernel).\n\nYou should be able to compile axTLS simply by extracting it, change into the extracted directory and typing:\n\n{{indent{{{{&gt;  make}}}\n\nSelect your platform type, save the configuration, exit, and then type &quot;make&quot; again.\n\nIf all goes well, you should end up with an executable called &quot;axhttpd&quot; (or axhttpd.exe) in the //_stage// directory.\n\nTo play with all the various axTLS options, type:\n\n{{indent{{{{&gt;  make menuconfig}}}\n\nSave the new configuration and rebuild.\n\n!!__Running it__\n\nTo run it, go to the //_stage// directory, and type (as superuser):\n\n{{indent{{{{&gt; axhttpd}}}\n\nNote: you may have to set your ~LD_LIBRARY_PATH - e.g. go to //_stage// and type //export ~LD_LIBRARY_PATH=`pwd`//\n\nAnd then point your browser at https://127.0.0.1 And you should see a this html page with a padlock appearing on your browser. or type http://127.0.0.1 to see the same page unencrypted.\n\n!!__The axssl utilities__\n\nThe axssl suite of tools are the SSL test tools in the various language bindings. They are:\n\n* axssl              - C sample\n* axssl.csharp    - C# sample\n* axssl.vbnet      - VB.NET sample\n* axtls.jar           - Java sample\n* axssl.pl           - Perl sample\n* axssl.lua         - Lua sample\n\nAll the tools have identical command-line parameters. e.g. to run something interesting:\n\n{{indent{{{{&gt; axssl s_server -verify -CAfile ../ssl/test/axTLS.ca_x509}}}\n\nand\n\n{{indent{{{{&gt; axssl s_client -cert ../ssl/test/axTLS.x509_1024 -key ../ssl/test/axTLS.key_1024 -reconnect}}}\n\n!!!!C#\n\nIf building under Linux or other non-Win32 platforms, Mono must be installed and the executable is run as:\n\n{{indent{{{{&gt; mono axssl.csharp.exe ...}}}\n\n!!!!Java\n\nThe java version is run as:\n\n{{indent{{{{&gt; java -jar axtls.jar &lt;options&gt;}}}\n\n!!!!Perl\n\n{{indent{{{{&gt; [perl] ./axssl.pl &lt;options&gt;}}}\n\nIf running under Win32, be sure to use the correct version of Perl (i.e. ~ActiveState's version works ok).\n\n!!!!Lua\n\n{{indent{{{{&gt; [lua] ./axssl.lua &lt;options&gt;}}}\n\n!__Known Issues__\n\n* Firefox doesn't handle legacy ~SSLv2 at all well. Disabling ~SSLv2 still initiates a ~SSLv23 handshake (v1.5). And continuous pressing of the &quot;Reload&quot; page instigates a change to ~SSLv3 for some reason (even though the TLS 1.0 option is selected). This will cause a &quot;Firefox and &lt;server&gt; cannot communicate securely because they have no common encryption algorithms&quot; (v1.5), or &quot;Firefox can't connect to &lt;server&gt; because the site uses a security protocol which isn't enabled&quot; (v2.0). See bugzilla issues 343543 and 359484 (Comment #7). It's all broken (hopefully fixed soon).\n* Perl/Java bindings don't work on 64 bit Linux machines. I can't even compile the latest version of Perl on an ~AMD64 box (using ~FC3).\n* Java 1.4 or better is required for the Java interfaces.\n* Processes that fork can't use session resumption unless some form of IPC is used.\n* Ensure libperl.so and libaxtls.so are in the shared library path when running with the perl bindings. A way to do this is with:\n\n{{indent{{{{&gt; export LD_LIBRARY_PATH=`perl -e 'use Config; print $Config{archlib};'`/CORE:.}}}\n* The lua sample requires the luabit library from http://luaforge.net/projects/bit.\n\n!!!!Win32 issues\n\n* Be careful about doing .NET executions on network drives - .NET complains with security exceptions on the binary. //TODO: Add a manifest file to prevent this.//\n* CGI has been removed from Win32 - it needs a lot more work to get it right.\n* The default Microsoft .NET SDK is v2.0.50727. Download from: http://msdn.microsoft.com/netframework/downloads/updates/default.aspx.\n\n!!!!Solaris issues\n\n* mconf doesn't work well - some manual tweaking is required for string values.\n* GNU make is required and needs to be in $PATH.\n* To get swig's library dependencies to work (and for the C library to be found), I needed to type:\n\n{{indent{{{{&gt; export LD_LIBRARY_PATH=/usr/local/gcc-3.3.1/lib:.}}}\n\n!!!!Cygwin issues\n\n* The bindings all compile but don't run under Cygwin with the exception of Perl. This is due to win32 executables being incompatible with Cygwin libraries.\n\n</div>

<div tiddler="axhttpd" modifier="YourName" modified="200804011308" created="200702242231" tags="">axhttpd is a small embedded web server using the axTLS library. It is based originally on the web server written by Doug Currie which is at http://www.hcsw.org/awhttpd.\n\n!@@bgcolor(#ff0000):color(#ffffff):axhttpd Features@@ \n\n!!__Basic Authentication__\n\nBasic Authentication uses a password file called  &quot;.htpasswd&quot;, in the directory to be  protected. This file is formatted as the familiar colon-separated username/encrypted-password pair, records delimited by newlines. The protection does not carry over to subdirectories. The utility program htpasswd is included to help manually edit .htpasswd files.\n\nThe encryption of this password uses a proprietary algorithm due to the dependency of many crypt libraries on DES. An example is in [[/test_dir/no_http|https://127.0.0.1/test_dir/no_http]]  (username 'abcd', password is '1234').\n\n//Note: This is an mconf enabled configuration option.//\n\n!!__SSL Protection__\n\nDirectories/files can be accessed using the 'http' or 'https' uri prefix. If normal http access for a directory needs to be disabled, then put &quot;~SSLRequireSSL&quot; into a '.htaccess' file in the directory to be protected. \n\nConversely, use &quot;~SSLDenySSL&quot; to deny access to directories via SSL.\n\nAn example is in [[/test_dir/no_http|http://127.0.0.1/test_dir/no_http]] and [[/test_dir/no_ssl|https://127.0.0.1/test_dir/no_ssl]].\n\nEntire directories can be denied access with a &quot;Deny all&quot; directive (regardless of SSL or authentication). An example is in [[/test_dir/bin|http://127.0.0.1/test_dir/bin]]\n\n!!__CGI__\n\nMost of the CGI 1.1 variables are now placed into the script environment and should work as normal.\n\n!!__Lua and Lua Pages__\n\nThis is a small scripting language gaining popularity in embedded applications due to its small footprint and fast speed.\n\nLua has been incorporated into the build, so simply select it and it will automatically install. Try pointing your browser at [[test_main.html]|http://127.0.0.1/lua/test_main.html]] to see an example of Lua Pages.\n\n//Note: This is an mconf enabled configuration option.//\n\n!!__Directory Listing__\n\nAn mconf option. Allow the files in directories to be displayed. An example is in [[/test_dir|http://127.0.0.1/test_dir]]\n\n!!__Other Features__\n\n* Timeout - HTTP 1.1 allows for persistent connections. This is the time allowed for this connection in seconds.\n* Daemon - Puts the process in daemon mode. \n* SSL  session cache size - The size of the session cache (a heavily loaded server should maintain many sessions). A session will save on expensive SSL handshaking.\n\n</div>
