Let 39;s Encrypt Authority X3 Root Certificate Download EXCLUSIVE

Our roots are kept safely offline. We issue end-entity certificates to subscribers from the intermediates in the next section.For additional compatibility as we submit our new Root X2 to various root programs, we have also cross-signed it from Root X1.

Similar to intermediates, root certificates can be cross-signed, often to increase clientcompatibility. Our ECDSA root, ISRG Root X2 was generated in fall 2020 and is the rootcertificate for the ECDSA hierarchy. It is represented by two certificates: one that isself-signed and one that is signed by ISRG Root X1.

Let's Encrypt is a free, automated, and open certificate authority brought to you by the nonprofit Internet Security Research Group (ISRG). Read all about our nonprofit work this year in our 2023 Annual Report.

As @ahaw021 said, you can download certs from Chain of Trust - Let's Encrypt but most people should not need to do this for most purposes, because their OS or browser CA bundle will typically already include IdenTrust's DST X3 root, which is the root that we customarily chain to for certificates that are being issued today.

So it was actually true that my application wasn't serving all the certificates needed. I was somehow confused by the name /etc/letsencrypt/live/scatologies.com/fullchain.pem, I was thinking it would contain all the certificate needed for verifying the host, but that's not true.

I can't answer for ISRG obviously, but have you realized that running your own public certificate authority costs a lot of money? This due to the fact that for a public CA to be recognised and trusted, you'd need your entire infrastructure to be audited. And somewhere on the internet I read a WebTrust audit could cost you $ 150 000! That's a lot of money.

There is no such thing as an "ssl authority".

SSL is something that can be done with a certificate [a requirement for SSL encryption].

The "authority" is the business that provides the certificate(s).

Thus a "Certificate Authority" (CA).

Not an SSL Authority (SA), if that even exists, which sounds more like "an expert witness" than a business.

I have the same issue, al the necessary intermediate and root authorities are installed, still the imported pfx lets encrypt certificates are marked with the red cross and the message "Certificate authority: Invalid or not installed Issuer

Over the weekend, Let's Encrypt posted an article about how they are changing their root certificate authority in 2021 ( -two-feet.html). Let's Encrypt has been cross signing with a broadly accepted root authority IdenTrust, but that is about to change in 2021. They will no longer be cross signing but using only their own root certificate authority. Specifically, they say that Android versions prior to version 7.1.1 do not yet trust Let's Encrypt's root certificate authority. The article says that this affects software / operating systems not updated since 2016.

Now that certbot is updated, it is able to do the desired certificate continuing from January 2021. The last step is to add a line to /etc/letsencrypt/cli.ini so that we activate that functionality. So I added

Let's Encrypt certs will now be cross-signed beyond the expiration date of the IdenTrust root certificate. I have updated the dates in my summary above to reflect this. The major change is that no one needs to make any changes before at least June 2021.

SSL/TLS connections provide a layer of security by encrypting data that moves between your client and DB instance. Optionally, your SSL/TLS connection can perform server identity verification by validating the server certificate installed on your DB instance. To require server identity verification, follow this general process:

The certificate authority (CA) is the certificate that identifies the root CA at the top of the certificate chain. The CA signs the DB server certificate, which is installed on each DB instance. The DB server certificate identifies the DB instance as a trusted server.

Uses a certificate authority with RSA 2048 private key algorithm and SHA256 signing algorithm. This CA expires in 2024 and doesn't support automatic server certificate rotation. If you are using this CA and want to keep the same standard, we recommend that you switch to the rds-ca-rsa2048-g1 CA.

If your application is on Microsoft Windows and requires a PKCS7 file, you can download the PKCS7 certificate bundle. This bundle contains both the intermediate and root certificates at -gov-west-1.rds.amazonaws.com/global/global-bundle.p7b.

In order for a certificate to be trusted, it must be signed by a certificate that belongs to a trusted CA. In order to be trusted, a CA must have the signing certificate bundled in the browser/OS. A CA that enters the market today, assuming they are approved to the root certificate program of each browser/OS from day 0 (which is impossible), will be included in the current releases of the various browser/OS. However, they won't be able to be included in older (and already released) versions.

To limit the compatibility issue, Let's Encrypt got their root certificate cross-signed by another older CA (IdenTrust). This means a client that doesn't include LE root certificate can still fallback to IdenTrust and the certificate will be trusted... in an ideal world. In fact, it looks like there are various cases where this is not currently happening (Java, Windows XP, iTunes and other environments). Therefore, that's the major downside of using a Let's Encrypt certificate: a reduced compatibility compared to other older competitors.

Edited to add:For the purpose of secure transmission this is not a big problem. But, if you want to verify that it is the actual company you were looking for that holds the domain name a whois lookup may not be enough. Class 2 or 3 or EV certificates have the advantage that the company and domain are verified by the certificate authority.

One more issue with using Let'encrypt is that in enterprise scenario we need to install certificate to load balancer and CDN provider as well. Not all CDN providers have APIs to change this automatically. Also as of now Let's encrypt's validity is of 90 days which complicates this process more.

In general, for any secured connection with the CC3220 as the client you will need to pass in the specific root CA certificate that will be used to verify the server's certificate chain. This certificate has to match the root CA cert that signs your server's certificate. The trusted root CA catalog is only a catalog of root CA cert hashes; it doesn't actually have the full root CA certs. Thus, you need to provide the actual root CA cert to be used when you start a secured connection with the CC3220. This root CA cert will have its hash compared with the one in the catalog to ensure authenticity, but other than that the catalog is not used during cert chain verification.

For the MQTT example the main thing you need to do is provide to correct root CA cert file to the serial flash with the filename specified in Mqtt_Client_secure_files of mqtt_client_app.c. Looking at the LetsEncrypt documentation it looks like all of their certificates are ultimately signed with the DST Root X3 root CA certificate. You can double check this by adding the following code to your SimpleLinkSockEventHandler case SL_SSL_NOTIFICATION_WRONG_ROOT_CA:

Once you have identified the root CA you need, you can either get it direct from the cert authority's website or you can actually copy it from your PC's root CA cert database following the instructions here:

Once you have the correct certificate flashed onto the CC3220 serial flash, you should no longer get error -688. The "ASN no signer to confirm" error basically means that the CC3220 cannot verify the authenticity of the server's cert chain since the root CA cert it was using the verify the chain doesn't match the root CA cert that's actually provided in the chain.

Any clients connecting to Slack should have this certificate installed. We ask that this be done as soon as possible, as it will be necessary for Slack to function properly in the coming months. If this root certificate is already installed and trusted, no action is needed at this time.

LetsEncrypt made a recent change where they swapped the intermediate certificate with name "Let's Encrypt Authority X1" for one with name "Let's Encrypt Authority X3". The issue is, the authority key for the updated certificate remained the same.

So, when I renewed by server certificates, they now were issues by "X3" authority, however since the key was the same, Windows cert store seems to build the certificate chain with the first result it finds (alphabetically?) which turns out to be the old "X1" cert.

Microsoft 365 leverages a number of different certificate providers. The following describes the complete list of known Microsoft 365 root certificates that customers may encounter when accessing Microsoft 365. For information on the certificates you may need to install in your own infrastructure, see Plan for third-party SSL certificates for Microsoft 365. The following certificate information applies to all worldwide and national cloud instances of Microsoft 365.

I realized that I use Letsencrypt for my Synology NAS and decided to analyze the difference between the certs issued for by Certbot manual step and the Synology automatic process and I have notice that while the intermediate certificates are the same, the root certificate are different . 17dc91bb1f
