letsencrypt VS JsonCpp

Compare letsencrypt vs JsonCpp and see what are their differences.

letsencrypt

Certbot is EFF's tool to obtain certs from Let's Encrypt and (optionally) auto-enable HTTPS on your server. It can also act as a client for any other CA that uses the ACME protocol. (by certbot)

JsonCpp

A C++ library for interacting with JSON. (by open-source-parsers)

  • SSL certificate requirements are becoming obnoxious
    8 projects | news.ycombinator.com | 26 Aug 2025
    It's strange: SSL certificates (and maybe domain name registrations?) are one of the only "ticking time bomb" elements present in every modern web stack, whether a static site or not. By "ticking time bomb" I mean that there's a hard date N weeks/months from now where your site will definitely stop working, unless some external pile of dependencies work smoothly to extend that date.

    Software didn't have that sort of "ticking time bomb" element before, I think?

    I think I understand why it's necessary: we have a single, globally shared public namespace of domain names, which we accept will turn over their ownership over the long run, just like real estate changes hands. So we need expiration dates to invalidate "stale" records.

    We've already switched over everything to Let's Encrypt. But I don't think anyone should be under the delusion that automation / ACME is failproof:

    https://github.com/certbot/certbot/issues?q=is%3Aissue%20ren...

    https://github.com/cert-manager/cert-manager/issues?q=is%3Ai...

    https://github.com/caddyserver/caddy/issues?q=is%3Aissue%20A...

    (These are generally not issues with the software per se, but misconfiguration, third-party DNS API weirdness, IPv6, rate limits, or other weird edge cases.)

    Anyway, a gentle reminder that Let's Encrypt suggests monitoring your SSL certificates may be "helpful": https://letsencrypt.org/docs/monitoring-options/ (Full disclosure: I wrote the most recent addition to that list, with the "self-hosted scripts".)

  • Nginx Introduces Native Support for Acme Protocol

    Last I was concerned with, this was the situation:

    https://github.com/certbot/certbot/issues/8345#issuecomment-...

    That’s been three years though. The EFF/Certbot team has lost so much goodwill with me over that, I won’t go back.

  • We Reduced the Impact of Zombie Clients
    1 project | news.ycombinator.com | 5 Jun 2025
    Certbot 4 does too: https://github.com/certbot/certbot/releases
  • I no longer have an old-school cert on my HTTPS site
    18 projects | news.ycombinator.com | 23 May 2025
    I don't understand the tone of aggression against ACME and their plethora of clients.

    I know it isn't a skill issue because of who the author is. So I can only imagine it is some sort of personal opinion that they dislike ACME as a concept or the tooling around ACME in general.

    We've been using LE for a while (since 2019 I think) for handful of sites, and the best nonsense client _for us_ was https://github.com/do-know/Crypt-LE/releases.

    Then this year we've done another piece of work this time against the Sectigo ACME server and le64 wasn't quite good enough.

    So we ended up trying:-

    - https://github.com/certbot/certbot on GitHub Actions, it was fine but didn't quite like the locked down environment

    - https://github.com/go-acme/lego huge binary, cli was interestingly designed and the maintainer was quite rude when raising an issue

    - https://github.com/rmbolger/Posh-ACME our favourite, but we ended up going with certbot on GHA once we fixed the weird issues around permissions

  • ACME with Google Domains using a DNS Zone in GCS DNS
    1 project | /r/googlecloud | 28 Jan 2023
    This seems to be not implemented in certbot, yet: https://github.com/certbot/certbot/issues/6566
  • OpenSpeedTest in docker through DSM Reverse Proxy - incorrect upload speeds
    2 projects | /r/synology | 20 Jan 2023
    If you do go with NPM or Traefik, under the covers it's using certbot to request/renew your certificates through Let's Encrypt using the DNS-01 challenge, meaning you can get wildcard certs and don't have to futz around with port forwards. Again I'd think Caddy has similar functionality, I just have not used it personally. Raw NGINX you probably don't want to try out yet considering it requires manually doing the configs
  • Certbot run.bat file identified as batloader trojan by windows defender. Windows defender alerted me of a trojan which appears to simply be the startup batch script for certbot. Currently running full system scan, but I suspect it to be a false positive. Any ideas?

  • Snap Store administrators removed signal-desktop from Ubuntu Snap
    14 projects | news.ycombinator.com | 3 Nov 2022
    certbot won't be missed. The code quality is pretty poor.

    https://github.com/certbot/certbot/issues 5000 bugs and it most of it can be replaced by much smaller tools

  • Good Use Of Golang?

  • Let's Encrypt Certbot Not Working on FreeBSD
    1 project | /r/freebsd | 1 Sep 2022
    I am trying to migrate off of Linux and back to FreeBSD, but I hit a problem today. The Let's Encrypt Certbot is not installing. A bit surprising, given how important it is. So I thought I would notify the community Here is my bug report. https://github.com/certbot/certbot/issues/9394
