style="font-weight: 400;">wolfSSL provides many different embedded libraries and products, one of which is the </span><a href="https://www.wolfssl.com/wolfssh/"><span style="font-weight: 400;">wolfSSH Lightweight SSH library</span></a><span style="font-weight: 400;">. wolfSSH is a lightweight SSHv2 server library written in ANSI C and targeted for embedded, RTOS, and resource-constrained environments - primarily because of its small size, speed, and feature set. It also includes many different example applications, such as an example client, echoclient, server, echoserver, and a port forwarding example.</span></p> <p><span style="font-weight: 400;">To configure the library when downloading it from GitHub (https://github.com/wolfSSL/wolfssh), the first step required is to run the </span><b>autogen.sh</b><span style="font-weight: 400;"> script from within the root directory of wolfSSH. This script sets up the library for use with autotools. Once the autogen.sh script has been run, the library can be configured as desired and then built. If downloaded from the wolfSSL website (</span><a href="https://www.wolfssl.com/download/"><span style="font-weight: 400;">https://www.wolfssl.com/download/</span></a><span style="font-weight: 400;">) use of autogen.sh is not required. The configure script can take many features, some of which are outlined below:</span></p> <table style="margin-left: auto; margin-right: auto; width: 50%;"> <tbody> <tr> <td><b>--enable-debug</b></td> <td><span style="font-weight: 400;">Add debug code - this turns off optimizations</span></p> <p><i><span style="font-weight: 400;">(default: disabled)</span></i></td> </tr> <tr> <td><b>--enable-keygen</b></td> <td><span style="font-weight: 400;">Enable key generation</span></p> <p><i><span style="font-weight: 400;">(default: disabled)</span></i></td> </tr> <tr> <td><b>--enable-scp</b></td> <td><span style="font-weight: 400;">Enable scp support</span></p> <p><i><span style="font-weight: 400;">(default: disabled)</span></i></td> </tr> <tr> <td><b>--enable-sftp</b></td> <td><span style="font-weight: 400;">Enable SFTP support</span></p> <p><i><span style="font-weight: 400;">(default: disabled)</span></i></td> </tr> <tr> <td><b>--enable-fwd</b></td> <td><span style="font-weight: 400;">Enable TCP/IP forwarding support</span></p> <p><i><span style="font-weight: 400;">(default: disabled)</span></i></td> </tr> </tbody> </table> <p><span style="font-weight: 400;">All of the wolfSSH configure options can be viewed by running the configure script with the "</span><b>-h</b><span style="font-weight: 400;">" option. These configure options may also be prefixed with "</span><b>--disable</b><span style="font-weight: 400;">" as well, to disable features that are enabled by default.</span></p> <p><span style="font-weight: 400;">The wolfSSH library can be downloaded by either cloning the wolfSSH GitHub repository (</span><a href="https://github.com/wolfssl/wolfssh.git"><span style="font-weight: 400;">https://github.com/wolfssl/wolfssh.git</span></a><span style="font-weight: 400;">), or by viewing the wolfSSL </span><a href="https://www.wolfssl.com/download/"><span style="font-weight: 400;">download page</span></a><span style="font-weight: 400;">.

To better assist our users with this feature we have setup a ready-made example in our GitHub examples repository and we are adding a section about CSR functionality to the wolfSSL manual. The example mentioned can be found using the link below:<br /> </span><a href="https://github.com/wolfSSL/wolfssl-examples/blob/master/certgen/csr_example.c"><span style="font-weight: 400;">https://github.com/wolfSSL/wolfssl-examples/blob/master/certgen/csr_example.c</span></a></p> <p><span style="font-weight: 400;">The new manual section will be in chapter 7: Section 7.9 “Certificate Signing Request (CSR) Generation” and is located on our website here: <a href="https://www.wolfssl.com/docs/wolfssl-manual/ch7/">https://www.wolfssl.com/docs/wolfssl-manual/ch7/</a></span></p> <p><span style="font-weight: 400;">Some notes on CSR’s and wolfSSL:</span></p> <p><span style="font-weight: 400;">To configure wolfSSL for CSR generation please add these options:<br /> </span><span style="font-weight: 400; font-family: Courier New;">./configure --enable-certreq --enable-certgen</span></p> <p><span style="font-weight: 400;">wolfSSL can generate a CSR for a requesting party which is then be sent to a Certificate Authority for use in issuing a certificate for that party.</span></p> <p><span style="font-weight: 400;">wolfSSL can either generate a certificate from scratch with all mandatory fields set or it can generate a CSR from scratch with optional fields excluded.</span></p> <p> </p> <p><span style="font-weight: 400;">Limitation:</span></p> <p><span style="font-weight: 400;">As some items are deemed “optional” in a CSR that are otherwise “mandatory” in a certificate, wolfSSL’s parsing engine does not yet support consuming a CSR for use in generating a certificate. The wolfSSL parsing engine strictly checks all features required in a certificate and considers them to be mandatory. Passing in a CSR that does not contain these features results in an error from the parsing engine at this time. wolfSSL does not yet have a timeline for adding the additional parsing rules to allow CSR consumption but if this is a feature you would like to see added please send the wolfSSL team a note at </span><a href="mailto:support@wolfssl.com"><span style="font-weight: 400;">support@wolfssl.com</span></a><span style="font-weight: 400;"> so an upvote can be added on your behalf to that feature enhancement! Unique users requesting a specific feature escalates the priority of that feature so let the wolfSSL team know!</span></p> <p><span style="font-weight: 400;">If you have any questions concerning CSR generation, feedback on the example provided, or anything else for that matter, please contact us anytime at </span><a href="mailto:support@wolfssl.com"><span style="font-weight: 400;">support@wolfssl.com</span></a><span style="font-weight: 400;">!

If you compile the wolfSSL library independant of your application using you MUST include the same configure options in the application as were used in the library.</p> <p>If building with “./configure” the build system will generate the file <wolf-root>/wolfssl/options.h with all the settings needed for your application. Simply add the lines:</p> <pre><code>#include <wolfssl/options.h> #include <wolfssl/wolfcrypt/settings.h> #include <wolfssl/ssl.h> /* other wolf headers below */</code></pre> <p>If building the wolfSSL sources directly the options.h will not contain any generated configuration. In that case our recommended option is to define the preprocessor macro “WOLFSSL_USER_SETTINGS” in your project and create your own “user_settings.h” file. Make sure the file is somewhere in your include path. You can use the same include pattern above, but exclude the options.h.</p> <p>Here are some example “user_settings.h” you can use for reference:</p> <ul> <li>Windows: /IDE/WIN/user_settings.h</li> <li>GCC ARM: /IDE/GCC-ARM/Header/user_settings.h</li> <li>NXP ARM: /IDE/ROWLEY-CROSSWORKS-ARM/user_settings.h</li> <li>Xcode: /IDE/XCODE/user_settings.h</li> </ul> <p>More information on managing the build configuration of wolfSSL can be found in <a href="https://www.wolfssl.com/docs/wolfssl-manual/ch2/">Chapter 2 of the wolfSSL User Manual</a>.
