I have changed to manual proxy, 127.0.0.1 on port 8080. That got me through to the certificates at http://mitm.it/ which I have downloaded and installed. But now firefox (latest version 89.0) is rejecting every web page because of mitmproxy. Under the advanced tab of the error page is this explanation:
Firefox uses the Mozilla CA store to verify that a connection is secure, rather than certificates supplied by the user’s operating system. So, if an antivirus program or a network is intercepting a connection with a security certificate issued by a CA that is not in the Mozilla CA store, the connection is considered unsafe.
Is there a workaround for this?

Trying to investigate private APIs on apps installed on my Android, I've noticed most modern apps use custom client certificate meaning with the trusted root certificate installed on the Android, Charles still cannot monitor the traffic because the server would reject the handshake from Charles. I imagine either I will need a different tool for the traffic monitoring or I will need to direct Charles to use some custom certificate file embedded in the app itself.
You need that certificate file at hand (I don't know if and how you can extract it from application).
You also need to know the passphrase (password) for that certificate. Charles will ask it when you connect to selected host for 1st time.
Then just use latest Charles (tested on version 4.2.1) menu Proxy -> SSL Proxying Settings, tab Client Certificates and add certificate (PKCS#12 key file) for selected host and port.
I have a windows desktop application which need to be communicated with our web page.So I've created a local server which runs on a port.I'm creating a socket from my webpage to the desktop application and the communication happens though that socket.
As my webpage runs on HTTPS, I need to create a secure socket ('wss'). SO I generated a self signed certificate for Ip 127.0.0.1 using openssl and I imported the certificate to windows trusted cerificate store.Now google chrome accepts it as a trusted certificate but the firefox rejects that certificate with the error Error code: SEC_ERROR_UNKNOWN_ISSUER .
We cant buy a SSL certificate for localhost domain from a CA. Is there any solution to overcome this problem? Is there any way to skip SSL check for socket creation?
How can I create a certificate which will be accepted by all the browsers as a trusted certificate?
Firefox can use the desktop store by setting this key to TRUE : security.enterprise_roots.enabled
To change this, open about:config with your Firefox and look for this key.
If you want to change this automatically for several desktops, have a look at this tutorial which is well done.
The other answer from Eugène Adell is good, but if you are on Linux, a policy file is required to trust the OS certificate authority.
Create a file "policies.json" in the "distribution" directory of the Firefox install location, and point it to the certificate file:
{
"policies": {
"Certificates": {
"ImportEnterpriseRoots": true,
"Install": ["localhost.crt","/path/to/cert/file"]
}
}
}

My application requires LWP under SSL, but I can't seem to get it to connect properly without receiving an error.
certificate verify failed)LWP::Protocol::https::Socket: SSL connect attempt failed with unknown error error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed at C:/Perl/site/lib/LWP/Protocol/http.pm line 51.
Whenever I load up the website in FireFox on my server, I receive
This connection is untrusted (Technical error: sec_error_unknown_issuer)
Whenever I load it up in Chrome, it verifies absolutely fine.
I can load the page up in FireFox and Chrome on my computer and receive no SSL verification errors at all.
I have no clue what is different between my PC and my server; they're both using the exact same FireFox versions so I'm not sure why it wouldn't verify properly on there.
I've tried workarounds by putting in $ENV{PERL_LWP_SSL_VERIFY_HOSTNAME} = 0 in the Perl script but it seems to throw the same exact error still.
This is the script I'm using to test HTTPS
Does anyone know any solution to this or any workaround?
I've tried workarounds by putting in $ENV{PERL_LWP_SSL_VERIFY_HOSTNAME} = 0
As the name of the option implies it cares only about disabling the check of the hostname against the certificate. It does not disable the validation of the certificate chain.
Whenever I load up the website in FireFox on my server, I receive ...
Since you get validation errors with Firefox and LWP but not with Chrome, Chrome has probably an additional CA as trusted which they others don't have.
From your code it looks like that you are using Windows and from my understanding Firefox comes with its own CA store, LWP uses Mozilla::CA (which contains the CAs usually shipped with Firefox) but Chrome uses the system CA store. Thus there is probably a CA in the system store which Firefox and LWP don't know about.
While it might be that there is some special esoteric CA which is known to the default Windows CA store but not to Firefox, it is more likely that you are behind some SSL inspecting firewall and that the administrators added the necessary proxy certificate to Windows CA store but not to Firefox or LWP's store. I would suggest you check the certificate chain inside the Chrome browser and look at the top (builtin) certificate.
If you consider the CA trusted you might export it and import it into Firefox. You might also make LWP use this CA by saving it in PEM format and then set the PERL_LWP_SSL_CA_PATH environment variable to point to the saved file or use the SSL_ca_path option in the ssl_opts setting to make LWP use this CA certificate for validation.
If this explanation does not lead to a solution please provide more details about the target URL you are trying to access and the network setup you have, especially if there is a SSL intercepting proxy or firewall. Please provide also information about the version of LWP you are using, because there changed a lot with version 6.
I have a few sites that have SSL Certificates installed. When an SSL request is made with my employer's iPhone, this error message is displayed:
Accept Website Certificate
The certificate for this website is invalid. Tap Accept to connect to this website anyway.
I've pulled up the same pages in other browsers, including Safari, and they do not show any issues with the certs.
These two URLs exhibit the problem:
https://www.powerlunchbunch.com/index.php?template=join&nav=20
https://www.councilonagingmartin.org/index.php?template=donate&nav=257
Additional Information:
Both SSL certs are issued by Network Solutions
The sites are hosted on Rackspace Cloud Sites
Update:
I now have an open ticket with Rackspace for this issue. I browsed the same sites in Firefox 4.0 Beta 7, and got this warning page, telling me that "The certificate is not trusted because no issuer chain was provided.":
I think it's because you (or your hosting company) haven't configured the full certificate chain on your web server.
Take a look at a report from an ssl checker, such as this:
http://www.sslshopper.com/ssl-checker.html#hostname=www.councilonagingmartin.org
...
I can see from this report that you're using Apache2.2. Configuring 'intermediate certificates' on Apache2 goes something like this:
SSLCertificateFile /etc/ssl/crt/yourDOMAINNAME.crt
SSLCertificateKeyFile /etc/ssl/crt/private.key
SSLCertificateChainFile /etc/ssl/crt/chainCert.xxx
I don't know if you configured the certificate yourself, or your hosting company configured it, so you'll either need to contact your hosting company, or the certificate provider, who can provide the intermediate certificate(s).
Hope That Helps
Unfortunately, the Root CA for both those certificates, Network Solutions, L.L.C. is not a trusted certificate authority on the iPhone.
If you look at the certificate chain, it does end up at AddTrust, which is a trusted CA on the iPhone.
So you likely have one of the following problems:
1) Your certificate is not installed correctly on the web server
2) You need to work with Network Solutions (the SSL cert issuer) to get a cert that properly chains to AddTrust.
I'm trying to see how a certain application is talking to a server in SSL. Basically, the process just hangs when it claims to have done some SSL communication. I want to debug the problem by catching the traffic, but I can't really use a sniffer since SSL will probably look like a hexdump.
Is there a good man-in-the-middle tool that I could use as instrumentation? I just need something that will show me the decrypted communication. Hopefully very easy to setup. I could even point the application to any IP address/port available to my machine (eg localhost:8888), so proxies would be fine. Also, I can probably configure the application to accept any certificate.
What do you use to simulate a man-in-the-middle (mitm) SSL attack?
UPDATE: I tried fiddler and can't get it to work. I installed openssl and typed the following command:
openssl s_client -connect smtp.gmail.com:465
Gmail responds with their certificate and a 220 mx.google.com ESMTP .... However, Fiddler does not capture the traffic. I set the WinINET options in fiddler to "Use the same proxy server for all protocols". Can anyone else get this to work (or not work)? I think I need to find a way to have openssl use a proxy.
Fiddler allows you to implement a man in the middle attack against yourself to see what is inside the SSL tunnel.
Fiddler generates a unique root SSL certificate for your computer, and then creates a session certificate signed by the root. When you configure Fiddler to decrypt SSL for you it acts as a proxy between you and the destination, decrypting the traffic using the site's SSL certificate and then re-encrypting it using its own certificate.
Your browser/application will see an untrusted certificate error. You can get around this error by choosing to trust Fiddler's root certificate.
The folks over at .Net Rocks did a great podcast episode on using Fiddler to sniff your traffic.
I haven't use it for this purpose but Fiddler should be able to do what you want.
Fiddler is a Web Debugging Proxy which
logs all HTTP(S) traffic between your
computer and the Internet. Fiddler
allows you to inspect all HTTP(S)
traffic, set breakpoints, and "fiddle"
with incoming or outgoing data.
Fiddler includes a powerful
event-based scripting subsystem, and
can be extended using any .NET
language.
Fiddler is freeware and can debug
traffic from virtually any
application, including Internet
Explorer, Mozilla Firefox, Opera, and
thousands more.
If you are using the amazingly useful Wireshark sniffer, then you can have it decrypt SSL if you are able to provide it the appropriate key files.
