Acme Client For Macos
Dec 14, 2015 Let’s Encrypt is a new certificate authority backed by Mozilla, Akamai, EFF, Facebook and others, which provides free, automated SSL/TLS certificates.The public beta started on December 3, 2015 and a whole lot of certificates have been issued already. Several clients to automate issuing, renewing and revoking certificates have been released both by the community and the Let’s Encrypt team. General description Via the lets-encrypt resource, SFTPPlus can act as an ACME client, in order to generate or renew certificates signed by Let’s Encrypt’s CA. The IETF-standardized ACME protocol, RFC 8555, is the ACME v2 protocol used by SFTPPlus when interacting with the Let’s Encrypt service.

Acme is a text editor and graphical shell from the Plan 9 from Bell Labsoperating system, designed and implemented by Rob Pike. It can use the Sam command language. The design of the interface was influenced by Oberon. It is different from other editing environments in that it acts as a 9P server. A distinctive element of the user interface is mouse chording.
Overview[edit]
Acme can be used as a mail and news reader, or as a frontend to wikifs. These applications are made possible by external components interacting with acme through its file system interface. Rob Pike has mentioned that the name 'Acme' was suggested to him by Penn Jillette of Penn & Teller during a movie night at Times Square when he asked for a suitable name for a text editor that does 'everything'.[4]
Ports[edit]
V2ray Client Macos
A port to the Inferno operating system is part of Inferno's default distribution. Inferno can run as an application on top of other operating systems, allowing Inferno's port of acme to be used on most operating systems, including Microsoft Windows and GNU/Linux. A project called acme: stand alone complex intends to make acme run as a standalone application on the host operating system.[5]
A working port of acme for Unix-like operating systems is included in Plan 9 from User Space, a collection of various ported programs from Plan 9. Currently it has been tested on a variety of operating systems including: Linux, Mac OS X, FreeBSD, NetBSD, OpenBSD, Solaris and SunOS.

Let’s Encrypt is a non-profit certificate authority that provides X.509 certificates for Transport Layer Security (TLS) encryption free of cost. The TLS certificate is valid for 90 days only. However, Due to the bug, they need to revoke many (read as “certain”) Let’s Encrypt TLS/SSL certificates. Let us see how to find out if you are affected by this bug and how you can fix it to avoid any problems with your TLS/SSL certificates.
The revocations start on 04 March 2020, and you need to renew your certificate before that; otherwise, your visitors will get an error about Invalid and expired/revoked certificate error.
Letsencrypt is revoking certificates on March 4
When a TLS certificate request contained N domain names that needed CAA rechecking, Boulder would pick one domain name and check it N times. What this means in practice is that if a subscriber validated a domain name at time X, and the CAA records for that domain at time X allowed Let’s Encrypt issuance, that subscriber would be able to issue a certificate containing that domain name until X+30 days, even if someone later installed CAA records on that domain name that prohibit issuance by Let’s Encrypt.
2020.02.29 CAA rechecking bug
From the forum thread:
On 2020-02-29 UTC, Let’s Encrypt found a bug in our CAA code. Our CA software, Boulder, checks for CAA records at the same time it validates a subscriber’s control of a domain name. Most subscribers issue a certificate immediately after domain control validation, but we consider a validation good for 30 days. That means in some cases we need to check CAA records a second time, just before issuance. Specifically, we have to check CAA within 8 hours prior to issuance (per BRs §3.2.2.8), so any domain name that was validated more than 8 hours ago requires rechecking.
How many certificates are affected?
According to project site 3,048,289, currently-valid certificates are affected, out of 116 million overall active Let’s Encrypt certificates. Of the affected certificates, about 1 million are duplicates of other affected certificates, in the sense of covering the same set of domain names.
How to check if I am using an affected Letsencrypt certificate
Linux, macOS and Unix users can use the curl command as follows:$ curl -XPOST -d 'fqdn=your-domain-name-here' https://unboundtest.com/caaproblem/checkhost
For example, I am going to check www.nixcraft.com certificate using the following syntax:$ curl -XPOST -d 'fqdn=www.nixcraft.com' https://unboundtest.com/caaproblem/checkhost
$ curl -XPOST -d 'fqdn=nixcraft.com' https://unboundtest.com/caaproblem/checkhost
Sample outputs:
Here is how it looks when the certificates affected by the bug:
There is an online tool for Windows and mobile users to check whether a host’s certificate needs replacement:https://unboundtest.com/caaproblem.html
If above tool is not working try the following manual method. First grab the database, run the following wget command:
How to check manually
$ wget https://d4twhgtvn0ff5.cloudfront.net/caa-rechecking-incident-affected-serials.txt.gz
Next find your domain serial number run (replace www.cyberciti.biz with your domain):$ openssl s_client -connect www.cyberciti.biz:443 -showcerts /dev/null | openssl x509 -text -noout | grep -A 1 Serial Number | tr -d :
Sample outputs:
Search for by the serial or domain name:$ zgrep '0704cf1cca2ef1c7abf433466b6231e0' caa-rechecking-incident-affected-serials.txt.gz
OR$ zgrep 'www.cyberciti.biz' caa-rechecking-incident-affected-serials.txt.gz
If you see the ‘missing CAA checking results for‘ message from the zgrep command for your domain name, force renew it ASAP.
How do I force renew the certificate to avoid this bug?
Pass the --force-renewal option to the certbot command to request a new certificate with the same domains as an existing certificate:$ certbot renew --force-renewal
Please note that if you see rate limit error, you need to create a certificate with the domain(s) you want and additional domain. For example, if I am getting a rate limit error for www.cyberciti.biz, I should try another sub-domain like test.cyberciti.biz. The syntax is as follows:$ certbot -d cyberciti.biz,www.cyberciti.biz,test.cyberciti.biz --expand
In my case I already had a certificate which includes cyberciti.biz, www.cyberciti.biz and it want one more certificate to get around rate limit error. So I added the test.cyberciti.biz. Make sure you include every domain name you want.
A note about acme.sh client
In many of my tutorials, I talked about acme.sh client, so the syntax is as follows:$ acme.sh -f -r -d www.cyberciti.biz -d cyberciti.biz
Where,
- -f : Used to force to install or force to renew a cert immediately
- -r : Renew a cert.
- -d DOMAIN_NAME : – Your domain names.
Verify that your certificate is no longer affected by the bug:curl -XPOST -d 'fqdn=www.cyberciti.biz' https://unboundtest.com/caaproblem/checkhost
Sample outputs:

Letsencrypt is revoking certificates on March 4, and it the inconvenient for many of its users. However, they are patching a critical bug, and I tested the renewal procedure for TLS certificates, which went smoothly. I encourage you to see the following URLs:
