How Dart Determines whether a Certificate is a Self-Signed Certificate - dart

When I made App with Flutter Dart, I had a problem communicating with the server. HTTPS could allow self-signed certificates, but WSS did not find a solution, so I wanted to know how Dart decided that my certificate was self-signed certificate.

Certificate error while setting SSL enabled for my Asp.Net MVC project

When I run the project with SSL I get a warning in the browser, in every browser: firefox, IE, edge, chrome. When I launch the project it doesn't show me the warning dialog and I don't know if I have any certificate installed.
How to check if I have the certificate installed and if not, how to install it?
You probably need to add your certificate to CA Root.
High level plan:
Export SSL certificate from IIS.
Import that SSL certificate into CA Root.
Here is a blog post that explains everything in detail and with screenshots.
If you use Google Chrome, you might need to close and re-open it after installing a new SSL certificate due to browser's caching.
You can use online SSL checker tool to diagnoses issues regarding SSL certificate installation.
You should check that you are using a self-signed certificate or a CA signed certificate. If it’s a self-signed certificate then your users will experience warning message when they browse your site because browsers don't recognize it.
If you have a CA signed certificate, then you received a certificate via email from trusted third-party certificate authority, which contains the root, intermediate and primary certificates. You should install all three files on your server.
You should update your all browser. Modern browsers have already implemented root certificate, so you need to configure only intermediate and primary certificate on the server.
Follow below link which may help you to add CA Root certificate in the Trusted Root Certification Authorities store. https://technet.microsoft.com/en-us/library/cc754841(v=ws.11).aspx

Access Development server with self-signed SSL Certificate

My app needs to connect to an internal web server through https.
The server has a self-signed certificate that is valid until next year:
I have installed this certificate in the iOS Simulator and on the device (Certificate.cer):
I am watching the traffic with Charles and the request does not even "leave" my computer.
The problem seems to be due to the SSL Certificate because when I can access the server through the internal url and the port 8080 everything works fine.
I did try the hack with the category allowsAnyHTTPSCertificateForHost:. This did not work in the simulator as well as on the device.
There seems to be official API to do this: How to use NSURLConnection to connect with SSL for an untrusted cert?
However, since this is only my development environment I would prefer not to change my code base for now. Plus I am using a framework to parse my data and I might have to deeply interfere with that framework to get to the API described above.
So my question is, should it not be possible to install the certificate and then use the server as if there was an official SSL certificate.
Email the self-signed certificate to yourself then open it on your iPhone. You will be taken through the steps to install the certificate on your phone.

Can I use self-signed SSL certificate server to deploy Enterprise app over air?

After iOS 7.1 ,if we want to deploy our Enterprise app over air, the URL for the manifest.plist file has to be HTTPS.
For example:
itms-services://?action=download-manifest&url=https://example.com/manifest.plist
In my server I use a self-signed SSL certificate. When I tap the URL on an iPhone, it says Could not connect to <ip-address> and logs the typical
NSUnderlyingError=0x15d37040 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be `<ip-address>`, which could put your confidential information at risk.
So, I want to know whether I can use the self-signed SSL certificate or not?
If I can, how do I resolve the problem the problem I've encountered?
First have the user install the self-signed SSL certificate on their device. Or use a free verified SSL service.
You will need to have the user install this file https://superuser.com/questions/97201/how-to-save-a-remote-server-ssl-certificate-locally-as-a-file
I believe this service provides browser-validated SSL certificates. https://www.startssl.com/?app=1

MDM: ssl issue for server url

I want to manage the iOS devices using Lion Server,I have purchased the Lion Server and installed in Mac system which has Lion OS 10.7.
I want to manage the devices with in our own network, I have not taken domain specific for MDM.
While creating cofig profile for MDM in IPCU,it needs the server url must begin with "https://".
So I am not able to install the MDM config profile in the iOS device, due to "htts".I tried to get ssl certificate for trial , but that is not available for private networks.
Is there any solution to resolve the issue with out purchasing ssl certificate or public domain.
Please correct me if I am doing something wrong and suggest the correct approach.
Self-signed ssl will work and while generating self-signed ssl certificate in server side,generate identity.p12 certificate and this certificate you need to use in identity section of IPCU.
And go through this also.
If you visit a page on the MDM web server with Safari and get the pop-up dialog warning about the identity of the server then you will need to install the SSL certificate on the device to allow the certificate to be trusted. This can be achieved by using iPCU or allowing the certificate from a web server.

Grails SSL certificate error

I'm using the acegi security plugin and I run the app -https. The cert is generated but I get a certificate warning when i visit the web page. I have then download the weak ssl plugin and added weakssl.trustAll =true to Config.groovy. But still getting the same warning. Have I left out anything?
The warning is normal. You can just accept the self-signed certificate. The weakssl module allows the Grails server to trust itself even if it provides a self-signed certificate. It has no effect whatsoever on the client. (Think what a horrible security hole it would be if you could just install some code on the server and get a client to accept a self-signed certificate without a warning!)
To solve your problem you need to either
manually tell your browser the certificate is OK by adding the certificate to your truststore
or
get a certificate from a trusted CA (Certificate Authority) a list of trusted CAs is stored in your browser. To get a certififate from a CA you need to proof your identity and pay (a lot) some money.
so I recommend you just accept the untrusted certifcate unless you want to buy a CA certificate.
The config you changed tells only the server to accept all certificates. i.e. if your server is connecting to another server
