  • Setting up a Homelab: Part 1 Proxmox and LetsEncrypt
    A self-signed certificate was generated and used by Proxmox which will always generate a warning on the browser. I did not like seeing this when trying to work on my home lab. So, I started looking for ways to put a valid SSL certificate in Proxmox. During my research, I found that Proxmox could be made to integrate with acme.sh; a free SSL certificate generator powered by ACME(Let's Encrypt). - Source: dev.to / about 2 months ago
  • Dehydrated: Letsencrypt/acme client implemented as a shell-script
    Dehydrated and acme.sh seems different. Is one of them fork? https://github.com/acmesh-official/acme.sh. - Source: Hacker News / about 1 month ago
  • How to Build Email Server with Exim on Alma Linux 9
    Next, we will install acme.sh, a command-line tool for managing SSL/TLS certificates. I prefer acme.sh over certbot, as it does not depend on the OS version. For more details about acme.sh, check its GitHub repo here. - Source: dev.to / 2 months ago

The "alternate chain" workaround will also stop working on June 6th. I need to support these older Android devices so I am looking for alternatives. I have seen ZeroSSL mentioned a few times; it is also the default CA... - Source: Hacker News / 2 months ago
  • I made a tool for automatically updating the current and next (rollover) TLSA DNS records with acme.sh and the Cloudflare API
    For the few people here that happen to run a self-hosted email server with acme.sh for TLS key/cert generation and Cloudflare for DNS management, I have made a tool that I personally use to get a perfect 100% score on Internet.nl's email test. Source: 6 months ago
