The path of the token file is included in the Match String of a content rule that is automatically created.Ĥ. The challenge is served by the HTTP/HTTPS Layer 7 Virtual Service.
That is what the Virtual Service that is selected when requesting a new certificate is used for. A token must then be placed in a specific location in the web server. The LoadMaster sends a request for the certificate.Ģ. This makes the process easy and no server-side modifications are required.ġ.
These steps are all performed automatically by the LoadMaster. Below is a description of the automatic steps performed by the LoadMaster after you request a new certificate. Kemp supports the HTTP-01 method for the challenge. You must prove that you have control over the FQDN for a certificate to be issued successfully. Let's Encrypt uses a challenge-based protocol. The following prerequisites must be in place before configuring Let's Encrypt on the LoadMaster:Ī LoadMaster with firmware version 7.2.53 or aboveĪ HTTP/HTTPS Layer 7 Virtual Service must be already configured with the ability to add a SubVS (so it should not have any Real Servers added) However, the content is in sync with the latest LoadMaster LTS firmware. This document has not required substantial changes since 7.2.54 LTS. Support for HTTP-01 domain validation methodĬertificate issuance (create Certificate Signing Request (CSR) and request certificates)Īutomatic/manual certificate renewal and automatic updating of renewed certificates on the LoadMaster
Open: The automatic issuance and renewal protocol is published as an open standard that others can adoptĬooperative: Much like the underlying internet protocols themselves, Let's Encrypt is a joint effort to benefit the community beyond the control of any one organizationĪs of LoadMaster firmware version 7.2.53, Kemp enables you to leverage the value of Let's Encrypt certificates by automating the renewal and updating of certificates across your applications. Transparent: All certificates issues or revoked are publicly recorded and available for anyone to inspect Secure: Let's Encrypt serves as a platform for advancing TLS security best practices, both on the CA side and by helping site operators to properly secure their servers The key principles for Let's Encrypt are:įree: Anyone who owns a domain name can use Let's Encrypt to obtain a trusted certificate at zero costĪutomatic: Software running on a web server can interact with Let's Encrypt to painlessly obtain a certificate, securely configure it for use, and automatically take care of renewal
It is a service provided by the Internet Security Research Group (ISRG).ĭigital certificates are issued to enable HTTPS (SSL/TLS) for websites for free in a user-friendly way. Let's Encrypt is a free, automated, and open Certificate Authority (CA).
