google chrome – Configure HTTPS access to the crostini container with a valid SSL certificate

I'm trying to generate an SSL certificate for crostini and have Chrome OS trust it:

  1. I generate a certificate by issuing the following commands and setting penguin.linux.test as common name:
openssl genrsa -out penguin.linux.test.key 2048
openssl req -x509 -new -nodes -key penguin.linux.test.key -days 1024 -out penguin.linux.test.pem
  1. Then I import the certificate into the chromeOS settings under Manage Certificates> Authorities.
  2. After starting a Web server with the certificates under port 8443, I try to access https: //penguin.linux.test/ using the Chrome OS browser.

However I receive the error NET::ERR_CERT_COMMON_NAME_INVALID

However. other links such as https://freemusicstudy.com/index.php?threads/6/#post-64 indicate that everything is perfect.
What is the problem? Could it be the image?

Facebook displays a blank image and preview after sharing an HTTPS link from my website

My site previously was only HTTP. I've used this website to share public information with my friends. I like to post news that I want, then share it on Facebook and when I post a link (HTTP link, my website still being HTTP), it correctly pulls the og tags from my site.

Yesterday I just moved my site from HTTP to HTTPS by getting free CloudFlare SSL. I redirect my website to HTTPS and check for mixed content errors. There is not one. Now, when I share my posts (which is now HTTPS) on Facebook, the name of my website is displayed:

My friend says that I have the og tags currently defined on my site:

Weather Outlook — Updicity



















How can I fix that? Could this be a Facebook cache problem or something?

SSL certificate – httpd and curl: Configure the https connection with a client validation as a p12 file

I deploy an httpd. I need to configure ssl to validate the client based on its client certificate.

To do this, I have a p12 file containing the private key, the client certificate and the ca string certificates:

CA certificate chain:

➜ ~ openssl pkcs12 -in fitxers.p12 -cacerts -nokeys
Bag Attributes
    ...
-----BEGIN CERTIFICATE-----
$$$$$$$...
-----END CERTIFICATE-----
Bag Attributes
    ...
-----BEGIN CERTIFICATE-----
$$$$$$$...
-----END CERTIFICATE-----

Cert client:

➜ ~ openssl pkcs12 -in fitxers.p12 -clcerts -nokeys
Bag Attributes
    ...
-----BEGIN CERTIFICATE-----
$$$$$$$...
-----END CERTIFICATE-----

Customer's private key:

➜ ~ openssl pkcs12 -in fitxers.p12 -nocerts
Bag Attributes
    ...
-----BEGIN PRIVATE KEY-----
$$$$$$$...
-----END PRIVATE KEY-----

To divide this p12 file in separate cert and key files:

➜ ~ openssl pkcs12 -in container.p12 -nocerts -out client.key.pem
➜ ~ openssl pkcs12 -in fitxers.p12 -clcerts -nokeys -out client.crt
➜ ~ openssl pkcs12 -in fitxers.p12 -cacerts -nokeys -out cacerts.crt

So, from now on, I have configured my httpd as follows:

SSLEngine On
SSLCACertificateFile /usr/local/apache2/conf/cacerts.crt
...

I'm trying to login using curl:

curl --cert client.crt --key client.key.pem https://localhost:8080/token -v
*   Trying 127.0.0.1...
* TCP_NODELAY set
* Connected to localhost (127.0.0.1) port 8080 (#0)
* ALPN, offering h2
* ALPN, offering http/1.1
Enter PEM pass phrase:

In the httpd server logs, I get:

Amazon web services – unable to connect to HTTPS on ec2 after Load Balancer configuration

  1. I have an EC2 instance with Amazon Linux running an Apache web server.

  2. I have an SSL ACM certificate issued. (I want to use it for a subdomain, so I configured it with * .mydomain.com and it was issued)

  3. I've set up a load balancer applicaiton with listners on the port 80 and 443 open. I have attached the SSL certificate to this one.

  4. I have configured my target group that contains my EC2 instance. I have configured port forwarding 80 according to the AWS documentation.

As far as I'm concerned, the only thing left for me to do is point to my domain, which is hosted by GoDaddy on my Load Balancer. I found a tutorial that said to create a A registration set Alias and add the DNS Namefor my load balancer as value. When I do that, he tells me that I can not have the A save because I already have a configuration but it's for my subdomain. I do it by the road 53.

When I give the A register a different name; for example, lb.test.example.com it does not connect to HTTP on the domain test.example.com. When I type lb.test.example.comI get the browser indicating that the site is not secure and then a Bad Gateway Fault.

What do I forget here?

JWT vs. Custom Encryption for REST APIs on https

For our REST API architecture, we are currently considering two options:

  1. Json Web Token – Professionals consider it to be an industry standard. We pass a key that adds an access control layer and also allows us to add secondary authorization restrictions on our backend. Session maintenance and associated security features are provided by default by Django. .

    The disadvantages are that the settings are open to everyone, it seems (and correct me if I'm wrong) that it is possible that if someone has access to our link, he can change a parameter which is not related to the main authentication process and therefore compromise the data.

  2. We have developed an internal encryption process that encrypts all settings. The advantages are that we are almost certain of never having been compromised, because even if the link would have been put in the hands of someone, they would not have been able to decipher it to consult it. the settings.

    The downsides are that we have to manage all the session data via our backend code in our tables, so we can not use the features of Django. In addition, the idea that what we are doing is not the industry standard.

What is the right way to decide in this situation and what are the factors to consider?

proxy – Pfsense with Squid and SquidGuard does not allow HTTPS traffic?

About 2 or 3 years ago, I installed a pfsense server to prevent a member of my family from accessing Facebook too often; they asked for it.

It worked well and they were allowed to access Facebook a specific time a day.

The situations have changed and they have moved and now I have found the old pfsense box to find error messages squid barking at the user when something with an SSL certificate does not match; or the server on the other end is not crazy about what we are doing here.

I have installed the self-signed certificate that we generated from the certification authority (which is still valid) and although I still can load / block sites in http format, it seems like I has many problems with HTTPS.

If I'm not mistaken in the last few years, TLS 1.3 is out, and when you set up this pfsense box, I think TLS 1.2 was the highest bar for that kind of thing.

The error messages seem to be quite varied. I will also gladly enjoy the log files if anyone needs me to check them, be it for Squid, SquidGuard or something related to the firewall.

I've also found a recent thread (2019) that says I should do this by checking ignore internal cert validation (but it looks like it could be for a reverse proxy server and not for a web content blocker proxy filter), but I do not know where to find it in the settings (and the parameters in pfsense are quite numerous). I was able, however, to find the parameters of the certification authority and the certificate, as well as those of Squid and Squid Guard.

It also seems that I am under Pfsense 2.3.1 Community Edition (I think they are currently on version 2.5) and FreeBSD 10.3-RELEASE-p3 (they are probably already on 11).

digital signature – Accept an https connection with an invalid certificate and validate the certificate before. This is possible?

I will integrate a new application in the coming weeks. But something that was told to me by the partner team was very strange.

The partner asks us to spend a .CSR file with information from our company: name, address, etc. Then they signed this file and send it back to us. From here, agree.

But after that, they said something like this:

[…] we will configure our system to limit certificate requests. If someone tries to apply without the certificate, our system will accept the connection without a certificate or with an incorrect certificate, but the system will respond with an error for the requests sent.

As far as I know, if the certificate is invalid, the https connection protocol will not accept the connection, whatever happens. What do I miss here?
