Generate Ssl Certificate And Key Ubuntu
Apr 21, 2016 How To Create a Self-Signed SSL Certificate for Apache in Ubuntu 16.04 Step 1: Create the SSL Certificate. TLS/SSL works by using a combination. Step 2: Configure Apache to Use SSL. We have created our key and certificate. And now you'll create the CSR from the key. With the CSR and the key a self-signed certificate can be generated: openssl req -new -key server.key -out server.csr openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt The last step consists of installing the certificate and the key, in Debian/Ubuntu usually in /etc/ssl.
- Apr 21, 2016 TLS/SSL works by using a combination of a public certificate and a private key. The SSL key is kept secret on the server. It is used to encrypt content sent to clients. The SSL certificate is publicly shared with anyone requesting the content. It can be used to decrypt the content signed by the associated SSL key. We can create a self-signed.
- How can I find the private key for my SSL certificate. If you just got an issued SSL certificate and are having a hard time finding the corresponding private key, this article can help you to find that one and only key for your certificate.
- Dec 19, 2019 Obtaining an SSL Certificate on Ubuntu. The first and foremost thing to do before proceeding is to get an SSL certificate for your website and domain. There are several types of SSL certificates as well as lots of SSL Certificate Providers.
An SSL certificate is an electronic ‘document’ that is used to bind together a public security key and a website’s identity information (such as name, location, etc.) by means of a digital signature. The ‘document’ is issued by a certificate provider such as GlobalSign, Verisign, GoDaddy, Comodo, Thawte, and others. For more information, visit the article: What is an SSL Certificate?
Jun 22, 2018 The java.util.HashMap.values method of HashMap class in Java is used to create a collection out of the values of the map. It basically returns a Collection view of the values in the HashMap. Syntax: HashMap.values Parameters: The method does not accept any parameters. Java generate all key values of a map. How to directly initialize a HashMap (in a literal way)? Ask Question. Whose instance initializer puts these values. (By the way, a map can't contain twice the same value, your second put will overwrite the first one. 'meow', // key, value 'bird', 'chirp' // key, value ); Map.of. Java 9 added a series of Map.of static methods to do. I am very new for Android development, and I am trying to use HashMap in Android sample project. Now, am doing sample project for learn android. I just store keys and values in HashMap, i want to s. Java8 streams: Transpose map with values as list. Ask Question Asked 3 years, 4 months ago. An idea could be to generate all value-key pairs from the original map and then group the keys by these values: import java.util.AbstractMap.SimpleEntry; import static java.util.stream.Collectors.groupingBy; import static java.util.stream.Collectors.
In most cases you’ll usually want to use a browser trusted SSL certificate, so a self-signed may not be what you need. In those cases you should buy an SSL from a provider, or get yourself setup with a LetsEncrypt SSL. However, there are times when you just need the SSL for internal test sites. In these cases you can generate a self-signed SSL to secure the connection, the only caveat being that you’ll have to accept an SSL warning when you load.
Generating a Self-Signed SSL on Ubuntu
- These instructions are intended for creating a self-signed SSL certificate and assigning it to a domain in Apache.
- I’ll be working from a Liquid Web Core Managed Ubuntu 14.04 server, and I’ll be logged in as root.
- View Loaded Apache Modules, Load SSL if Necessary
- First let’s view whether Apache 2 already has the SSL module loaded using information from our article on How to List Which Apache Modules are Enabled on Ubuntu:
apache2ctl -M grep ssl
The module is already loaded if the result of the above command is:ssl_module (shared)
Otherwise, we need to load the SSL module:a2enmod ssl
The output of that command should look similar to:Considering dependency setenvif for ssl:
Module setenvif already enabled
Considering dependency mime for ssl:
Module mime already enabled
Considering dependency socache_shmcb for ssl:
Enabling module socache_shmcb.
Enabling module ssl.
See /usr/share/doc/apache2/README.Debian.gz on how to configure SSL and create self-signed certificates.
To activate the new configuration, you need to run:
service apache2 restart - And now we’ll restart Apache:
service apache2 restart
- First let’s view whether Apache 2 already has the SSL module loaded using information from our article on How to List Which Apache Modules are Enabled on Ubuntu:
- Setup the Environment, and Create the Self-signed SSL Certificate
- Make a directory to store the certificate and the server key:
mkdir /etc/apache2/ssl
- Generate the SSL via OpenSSL with the following command:
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/apache.key -out /etc/apache2/ssl/apache.crt
The command above generates a 2048-bit private key and corresponding CRT. These will remain valid for 365 days and the files are placed into the new directory. The output of the above command will result in the following, of which you’ll need to answer a few questions:Generating a 2048 bit RSA private key

You are about to be asked to enter information that will be incorporated into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]: US
State or Province Name (full name) [Some-State]: Michigan
Locality Name (eg, city) []: Lansing
Organization Name (eg, company) [Internet Widgits Pty Ltd]: Liquid Web
Organizational Unit Name (eg, section) []: KB
Common Name (e.g. server FQDN or YOUR name) []: kb.thebestfakedomainnameintheworld.com
Email Address []: email@thebestfakedomainnameintheworld.com
It is very important that the Common Name be set appropriately. Enter your fully qualified domain name (FQDN) here or, if you don’t have an FQDN, then your site’s IP address. - Make a directory to store the certificate and the server key:
- Add the Self-signed SSL Certificate to Apache
For a refresher on editing files with vim see: New User Tutorial: Overview of the Vim Text Editor- Now that the private key and associated CSR have been generated, we need to edit the SSL configuration file for Apache:
vim /etc/apache2/sites-available/default-ssl.conf
- Find the section:
VirtualHost _default_:443
- Then, find:
ServerAdmin webmaster@localhost
- And add the following Virtual Host configuration on the next line:
ServerName kb.thebestfakedomainnameintheworld.com:443
Be sure to replace kb.thebestfakedomainnameintheworld.com with your fully qualified domain name or server IP address for your Virtual Host. Keep in mind, that the domain should be the same as the Common Name specified in the previous step. - Verify that the following variables are set appropriately in the same file:
SSLEngine on
SSLCertificateFile /etc/apache2/ssl/apache.crt
SSLCertificateKeyFile /etc/apache2/ssl/apache.key
Then exit and save the file with the command :wq .
- Now that the private key and associated CSR have been generated, we need to edit the SSL configuration file for Apache:
- Activate the Virtual Host
- Activate the virtual host with the command:
a2ensite default-ssl
- Then restart Apache once more:
service apache2 restart
- Activate the virtual host with the command:

In this tutorial my test domain was kb.thebestfakedomainnameintheworld.com, so I can now visit https://kb.thebestfakedomainnameintheworld.com to test the SSL certificate setup. Use https://yourdomain to test your new self-signed SSL certificate!
And I never considered using any program. I have not seen a greater program. Ms office 2013 product key generator free download. Get excellent and qualified results. I do all of the presentations with Powerpoint for years. I’m a 20-year-old, MS office user.
