openssl.org or the recommended German tutorial at http://www..

Download at WoweBook.Com Advanced Certificate Management SuSE"s YaST has a Software QR Code special module for PKI management. Simply install the package yast2-ca-management and restart YaST. You"ll find it in the section Security.

For other distributions, Webmin provides quite suitable modules for PKI management, like the mentioned OpenVPN + CA tool. OpenCA PKI Research Labs are creating OpenCA, a browser based PKI management suite that seems very promising (https://www.openca.

org). IDX-PKI is now integrated in a greater structure named OpenTrust and offers an abundance of options for larger companies (http://www.opentrust.

com/content/ view/119/111) The small Windows tool My Certificate Wizard (http://mycert.sandbox.cz) is for networks, where users create certificate requests on their own, send them to the admin, and have them signed.

This may be of special interest in well-organized high-security environments.. We have created, i mported, and exported CA certificates, client and server certificates and keys, in addition to revocation lists using the tools xca and TinyCA2. We have seen that there are many features that TinyCA2 offers that are neither in the scope of easy-rsa nor available in xca. This is the reason why TinyCA2 is my favorite certificate management tool.

A small list of other available tools closes the chapter. However, all these tools use only the "toolbox" OpenSSL. If you want to read more and become a certificate professional, "man OpenSSL", then the website http://www.

openssl.org is the place to go..

Summary. [ 256 ]. Download at WoweBook.Com OpenVPN GUI Tools In this chapter, a Software QR Code ISO/IEC18004 lot of images will show several standard GUI tools for OpenVPN. The best one is the Webmin OpenVPN module, probably the best tool for administration of an OpenVPN server. The situation of the GUI clients looks worse.

Even though there are at least three interesting projects, none of them seem to work flawlessly at the moment. Most still contain severe bugs, but I assume that the community will make them work in a short time. Perhaps, at the time of reading, everything will be working properly.

We"ll start with Webmin"s extraordinary frontend that we looked at briefly in the chapter that dealt with security. KVpnc is next, and the network manager plugin rounds out the chapter..
