GnuPG is a complete and free implementation of the OpenPGP standard encryption. 

Installing GPG

GPG is available in Windows and many distributions of Linux, including a graphical user interface (GUI) that is easy to use. However, I prefer using the command line tools instead.

Red Hat / CentOS

sudo yum install gnupg

Ubuntu / Debian

sudo apt-get install gnupg

Note: Use gpg2 (version 2.x)

Laptop with encryted code - Markus Spiske

When installing a SSL certificate with a private key that is encrypted with a passphrase, you must decrypt the private key first. You can identify whether a private key is encrypted or not by opening the private key (.key or .pem file) using a text editor or command line. You should see the text ENCRYPTED if the private key is encrypted.

Windows servers use .pfx files which contain the public key file (SSL certificate file) and the private key file. However, this can also be converted to .pem files to  be used on Linux server using OpenSSL.

When making changes in your httpd-vhost.conf file, make sure to test it before reloading the apache config file or restarting apache.


apachectl configtest


/Applications/XAMPP/xamppfiles/bin/apachectl configtest

Errors should display, if there are any, otherwise you'll see the Syntax OK to indicate that there are no errors and you can reload the apache config file or restart apache.

Find and rename %20 from file names with a space in terminal

At times, there are differences between your local or staging and production environment in handling URL encodings. In strict environments (likely production), HTML links to files with encoded characters in their file name will result to a 403 (not found) error. Therefore, you must rename the file names in your directory.

Install rename utility

In MacOS, use homebrew to install the rename utility.

If you’re using multiple Webex accounts, you might get stuck signing-in to the same account even though you login into another when starting or joining a meeting using the Webex Meetings app. This certainly might get annoying but here is the work-around.

For MacOS (Catalina), what you have to do is clear your saved logins using the Keychain Access app.

I finally figured out how to make Google Translate work with the Drupal 8 site! I kept getting a 403 forbidden message whenever I change the language. This is because of the Drupal security directive in place in the .htaccess file.
