I have an app which is registered with a third party Identity Provider(Azure Active Directory). I am implementing Single Sign On using SAML 2.0. For this to work, I have to import a certificate file provided by Azure and import it on my local machine in a keystore. I also need to generate a private key against the same keystore. Everything is working well on my machine.
Now i am not sure where to install these certificates on AWS. I would be having a Load balancer to create multiple instances. So my confusion is where to add this certificate so that all my instances would have this certificate installed.
you need to import your ssl certificate in AWS Certificate Manager, then you can use it to terminate ssl in your AWS Load balancer, here is a guide to import third party ssl certificate in ACM, Link

I am working in Ec2 instance. I have connected my php files like http://13.57.220.172/phpinsert.php. But it is not secured site. So i want to convert http into https://13.57.220.172.
I have cloudflare ssl. When i try to add ssl certificate. It shows
com.amazonaws.pki.acm.exceptions.external.ValidationException: Provided certificate is not a valid self signed. Please provide either a valid self-signed certificate or certificate chain. Choose Previous button below and fix it.
i have enclose the image with it.
So how can i get the self signed certificate. is there any online tool available.
I think the error message your seeing has to do with this sentence:
If your certificate is signed by a CA, you must include the
certificate chain when you import your certificate.
from https://docs.aws.amazon.com/acm/latest/userguide/import-certificate-prerequisites.html.
Since it sounds like you're not yet in "production" mode, I'm guessing you're not particularly attached to your existing certificate, but just want a certificate to be able to do HTTPS on your web server (and don't really care if it's self-signed).
If you want to use AWS Certificate Manager, I think it would be easier to just let them (AWS) issue you a certificate instead of trying to import one from somewhere else. AWS doesn't charge anything for certificates. https://docs.aws.amazon.com/acm/latest/userguide/acm-billing.html
Even if you get the certificate setup in AWS Certificate Manager, that's not going to be installed directly on your EC2 instance, but rather (most likely) on a load balancer in front of your web server, which will add a little complexity to your setup. https://docs.aws.amazon.com/acm/latest/userguide/acm-services.html
If all you want to do is use HTTPS on your web server, Let's Encrypt (also free) is probably a simpler option. If you are using AWS Linux 2, there are instructions for getting a certificate here - https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/SSL-on-amazon-linux-2.html
Well, add to the points which #jefftrotman has already mentioned.
If your expectation is to just secure your IP address using HTTPS you can achieve that using the below approaches:
A SELF SIGNED certificate that you can create using OpenSSL.
You can also get an SSL certificate from a trust signing authority like (GoDaddy or VeriSign) or Let's encrypt.
The only requirement in the second point is that for getting a certificate from a valid signing authority you need to have a domain name like "myphpapp.com" and then use this domain to get the SSL certificate.
The below details are in case you want to use AWS ACM(Amazon Certificate Manager)
If you prefer ACM, you can get the free Public SSL certificate which you can map to the IP address and your web application will be secured.
If your requirement is to add SSL certificates (like PEM files) to a web server like
NGINX or Apache then you first need to create a Private CA using in ACM and then you using this CA you will be able to create Private SSL certificates. After creating those you can export the files and add those files to the configuration file. (try to use Amazon Linux 2) ec2 image for ease.
I have been working with web services connecting to URLs provided by different clients and so far it has all been done using one-way authentication. Now I'm asked to enable 2-way (mutual) authentication for one of the clients. I did a lot of research and reading but still confused about a lot of things.
I could test successfully on my local machine following instructions from various different articles. But the problem is now to deploy it in production.
Here's what I did for testing: I created a test Web service Host and assigned it a self-signed certificate and created a client to test this. After this I created a client certificate using makecert and verified that this is installed via MMC. I then modified my Host app to only allow clients with certificate and tested from client to see the connection refused due to not providing the client certificate. Then I modified the bindings in the client application to include the certificate name and I was able to connect to the Host successfully. So this completes local hosting.
Now the real problem. The tech team is going to create a certificate in "cert store" on the server. And I need to test again to make sure everything works as expected. We have a few different developers who all want to test on their machines on their local code. Can we all use the same certificate somehow? I don't think we would be allowed to import the certificate but what suggestions could I give them so all of us can use the same certificate?
I'm also confused about issues like difference between windows certificate and IIS certificate. What advantages would the IIS certificate provide?
Thanks for help!
Edit: Could one of the differences between installing on IIS be so that the hosted sites be accessed via SSL connection? This would mean we don't really need to install on IIS if it's just a client certificate. Is this correct?
I have WSO2 API manager deployed in AWS EC2 instance.
I have purchased a SSL certificate via sslforfree.com. I tried to import it via keytool command. But its not working and throwing error. It gives me
KrbException: Cannot locate default realm
How can I associate this certificate with the API Manager? I don't have a domain name for WSO2 and I access it via IP address.
Is it possible for have CA signed certificate in this case?
In case if I want a domain name for this EC2, how can I have one?
You can import the certificate inside Carbon. Log into <your_server>:9443/carbon as admin. After that go on Main -> Manage -> Keystores -> List
If you're still using the default settings you'll have the wso2carbon.jks entry here. Click on Import cert, chose your cert file and click on Import. Your certificate should be working after this.
there are several topics in this question:
I tried to import it via keytool command.But its not working and
throwing error.It gives me KrbException: Cannot locate default realm
The keytool gives you this exception? It would be useful to provide the keytool command you've used. There's not reason for that exception.
please not that the certificate CN must be the same as the fqdn (domain name) of the server (how your browser access it).
How can I associate this certificate with the API Manager?
There are two options.
Import the keypair (private key and certificate chain) into a keystore and configure the APIM to use the keystore (in the repository/conf/tomcat/catalina-server.xml)
Have a reverse proxy server (Apache HTTP, NGinx), and configure the SSL on that proxy server. This is my favorite approach .
See: https://docs.wso2.com/display/AM210/Adding+a+Reverse+Proxy+Server
Then you have control over who/where can access the carbon console, store and publisher.
I don't have a domain name for WSO2 and I access it via IP address. Is
it possible for have CA signed certificate in this case?
Certificate authorities don't provide IP based certificate, as they can validate ownership/control of a domain name, but not of the IP address.
You can create (and made trusted) your own CA and certificate (good for PoC, DEV environment, ..) but in long run you'll need a trusted certificate on a hostname.
In case if i want a domain name for this EC2 , how can i have one ?
You can always buy one :D For start - when having EC2 instance with a dynamic IP address, you may use some dynamic dns service (e.g. https://ydns.io/ , just search for more if you wish)
our customer using Websphere 7 decided to no longer use the self-signed certificates, but from now on always use some CA certificates.
I was browsing via the Security guide for Websphere environment and SSL settings, and just found this information:
A CA client must be created to connect to the CA server before
creating a CA certificate. You need to implement the
com.ibm.wsspi.ssl.WSPKIClient interface to enable WebSphere
Application Server security to communicate with a remote CA. The class
name needs be provided as part of the CA client when it is created
I am not sure if I understand it correctly. But for the situation, where I already have some CA certificate, and I just want to import it onto our environment, do I need to implement this interface?
Does that mean, that if I need to switch from self-signed certificates on Websphere to CA certificate, our software needs some implementation change?
I would expect only importing new truststores, keystores etc. but no java implementation.
Does someone have the knowledge about this change?
But for the situation, where I already have some CA certificate, and I just want to import it onto our environment, do I need to implement this interface?
No, you don't need to implement this interface, you can just import your certificates into your environment (to trust and key stores).
This interface is required if you would like to have automatic management with remote CA e.g. if certificate expires to allow WAS to automatically connect to CA and request for new one.
I have created a pem and crt file to use with my EC2 instance on AWS. I have 2 questions here:
1) The configuration instructions say: "Normally, at this stage you would submit your CSR to a Certificate Authority (CA) to apply for a digital server certificate." To whom do I send the certificate and how do I do it? Sorry, first time for me.
2) I am horribly confused about the uploading process to AWS. I have seen articles on uploading to a load balancer and uploading to IAM. I am using an EC2 instance and not, as far as I know a "load balancer" and I do not use IAM security. So how should I upload and what do I need to do?
Yours very confused seeking help ...
To get an SSL certificate signed you need to submit it to a trusted company, known as a Certificate Authority (CA). Think of your CSR like a blank cheque, nobody will trust it until it's signed by someone trustworthy.
There are commercial CAs which vary greatly in price, alternatively there are free CAs such as CACert (which I haven't used). The general process is: upload your CSR to the CA's site & the CA will provide a signed certificate.
If you want more information on what a CA's role is wikipedia is a great place to start, excerpt below:
In cryptography, a certificate authority or certification authority (CA) is an entity that issues digital certificates. A digital certificate certifies the ownership of a public key by the named subject of the certificate. This allows others (relying parties) to rely upon signatures or on assertions made by the private key that corresponds to the certified public key. In this model of trust relationships, a CA is a trusted third party – trusted both by the subject (owner) of the certificate and by the party relying upon the certificate. Many[quantify] public-key infrastructure (PKI) schemes feature CAs.
For serving SSL traffic you have two options:
A common web pattern is to "Terminate SSL at the load balancer", which just means the load balancer will host and serve the SSL certificate, then simply sends traffic to the web server (your EC2 instance) via http. This is generally considered safe as the last hop is within your infrastructure.
If you want to go without a load balancer you'll need something on the EC2 instance to serve the SSL certificate. Here again there are plenty of options but generally installing Nginx or Apache on your instance to sit in front of your app works well.
Example configuration for Apache & Nginx are plenty & you should be able to find specific instructions for what-ever language & framework you're using but they're all fairly similar.
The play framework doco has examples for both Apache & Nginx sitting in front of a web app running on the same (EC2) server on port 9000 which should work for pretty much anything running on that port.
Plenty of reading to get you on your way, hope it helps!
