I have a network load balancer which redirects my request to an instance which has mqtt hosted on it and I have a python script which sends the traffic to the NLB. This is currently working on tcp and I want to make this connection secure so I have added a listener on port 8883 on my network load balancer and I have added acm certificate to it. Now I want to add this ACM certificate to my python script. How do I import this ACM certificate to my localsystem and add it to the python script?

AWS ACM public SSL certificates can't be exported.
If you require to have control of a private key from your SSL cert, you need to get it from a third party, not from ACM. A popular choice is https://letsencrypt.org/ which provides free SSL certificates.

If I create a new AWS Application Load Balancer (ALB) using HTTP, then AWS will create a load balancer with a randomly assigned domain name. Why can't AWS do the same thing when I create a new ALB using HTTPS? Instead, when creating a new ALB using HTTPS, AWS requires me to provide a custom domain name and custom certs.
The reason is that for valid public SSL certificate you require your own domain that you control. You can't register the certificate for the default domain provided by AWS for ALB because this is not your domain.
Having SSL certs is a lot of work, including managing its registration and renewals. I guess AWS does not want to do that, though they provide SSL for CloudFront AWS-provided default domains.
great question...
With many other aws tools like Amplify you will get a working https address on random aws domain, without the need to upload a certificate to a custom domain.
here They force me to use a certificate, which forces me to use aa custom domain and not the random autogenerated aws https address.
As per the docs - https://docs.aws.amazon.com/elasticloadbalancing/latest/application/create-https-listener.html
To use an HTTPS listener, you must deploy at least one SSL/TLS server
certificate on your load balancer. The load balancer uses a server
certificate to terminate the front-end connection and then decrypt
requests from clients before sending them to the targets.
The load balancer requires X.509 certificates (SSL/TLS server
certificates). Certificates are a digital form of identification
issued by a certificate authority (CA). A certificate contains
identification information, a validity period, a public key, a serial
number, and the digital signature of the issuer.
When you create a certificate for use with your load balancer, you must specify a domain name.
You could use Amazon's ACM to provision your certs. You will only be charged for the application as mentioned in the docs below - https://docs.aws.amazon.com/acm/latest/userguide/acm-billing.html
I have a network load balancer which has my mqtt instance as target.I have hosted mqtt server on my instance and I have a python script which sends traffic to my mqtt instance via network load balancer. It currently works on TCP. Now I want to make the connection secure between network load balancer and my client so I have added a listener which listens on port 8883 and I have attached acm certificates on it. Now my issue is how do I get client certificate which I will add to my python script? Any help would be appreciated.
If you generate a certificate via the public ACM CA you are not able to export the certificate, you will only be able to associate it with managed AWS resources such as elastic load balancers, CloudFront, VPNs and API Gateway.
If you want to be able to control the physical certificate your choices are limited to the below:
AWS ACM Private CA, this is an extended part of the ACM service but can be expensive.
A free SSL signing service such as certbot, these will need to be rotated more frequently than your standard CA.
Purchase an SSL through a trusted certificate authority
Now my issue is how do I get client certificate which I will add to my python script?
You can't export your certificate out of ACM. If you require to have control of a private key from your SSL cert, you need to get it from a third party, not from ACM.
ACM certs can only be used on load balancer, API gateway and CloudFront distro. If you want to use SSL cert somewhere else, you must get it from a third party. A popular choice is https://letsencrypt.org/.
I'm creating a simple website. The frontend is stored in S3, and hosted by Cloudfront. I managed to add a trusted SSL certificate to my frontend domain (www.xyz.com) using AWS Certificate Manager.
The backend is running on an EC2 instance. I added a self-signed certificate to it. I'm able to hit the APIs using Postman but the requests from frontend are failing because of the self-signed certificate.
I checked the AWS Certificate Manager again if it could provide me with a cert for my backend server, but it requires a domain. My server is running on an IP and port, and I couldn't find any service that provides a certificate for an IP. I don't want to spend extra money to get a domain for my backend.
So how do I get a trusted SSL certificate for a backend server, running on something like 10.12.12.10:9000?
couldn't find any service that provides a certificate for an IP.
This is because you need domain to obtain valid public certificate. You can't register SSL cert for an IP. But if you already have your own domain www.xyz.com, you can get a certificate for its subdomain, e.g. api.xyz.com.
However, ACM certs can't be used on instances. Thus, you need to get a valid public SSL cert from a third party. A popular choice is https://letsencrypt.org/ with certbot which provides free SSL certificates. By the way, StackOverlow is using letsencrypt for its SSL cert provider, thus its widely used and trusted ssl provider.
I am trying to use an amazon SSL certificate for my app. Currently, I have dockerized application hosting on the AWS server with envoy front-proxy. I am using lets-encrypt SSL certificates for a trusted domain certificate. Now I want to switch it with amazon's SSL certificates.
I am exploring this but I didn't get any clear idea. This blog show how to enable traffic encryption between services in AWS App Mesh using AWS Certificate Manager. but they have not mentioned how to do it with enovy proxy.
For envoy, we have to provide cert and key files. But as per this question, we are not able to download these files from amazon. Is it possible to use the Amazon certificate with envoy front-proxy? If yes then can you please give me the idea/example of how to do it?
Thanks in advance..
Only AWS Services can use AWS SSL Certificates. If you want to use an AWS SSL Certificate for TLS/HTTP traffic you would use an Application Load Balancer to handle the certificate and send it to your Envoy proxy hosted on an EC2 box. Ideally you would keep the network traffic encrypted which would require you to use a LetsEncrypt certificate between the Application Load Balancer and EC2.
When I deploy apps on Google App Engine, they automatically get use of the appspot.com wildcard SSL cert allowing me to have https secure URLs.
Does AWS give you this option, or is installing your own SSL cert the only option?
Amazon only provides free SSL certs through the ACM service, which is currently restricted to CloudFront distributions and Elastic Load Balancers that you have configured with your own custom domain name.
There are other ways to obtain a free SSL cert if you own your own domain name, such as CloudFlare and Let's Encrypt.
