skanjo / Howto convert a PFX to a seperate .key & .crt file
Last active January 29, 2016 16:58 — forked from TemporaryJam/Howto convert a PFX to a seperate .key & .crt file
How to convert a .pfx SSL certificate to .crt/key (pem) formats. Useful for NGINX
source: http://www.markbrilman.nl/2011/08/howto-convert-a-pfx-to-a-seperate-key-crt-file/
`openssl pkcs12 -in [yourfile.pfx] -nocerts -out [keyfile-encrypted.key]`
What this command does is extract the private key from the .pfx file. Once entered you need to type in the importpassword of the .pfx file. This is the password that you used to protect your keypair when you created your .pfx file. If you cannot remember it anymore you can just throw your .pfx file away, cause you won’t be able to import it again, anywhere!. Once you entered the import password OpenSSL requests you to type in another password, twice!. This new password will protect your .key file.
Now let’s extract the certificate:
`openssl pkcs12 -in [yourfile.pfx] -clcerts -nokeys -out [certificate.crt]`

Install Oracle JDK on CentOS

Install Oracle Java 8 JDK

Note: If you would like to install a different release of Oracle Java 8 JDK, go to the Oracle Java 8 JDK Downloads Page, accept the license agreement, and copy the download link of the appropriate Linux .rpm package. Substitute the copied download link in place of the highlighted part of the wget command.

Change to your home directory and download the Oracle Java 8 JDK RPM with these commands:

cd ~
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u72-b15/jdk-8u72-linux-x64.rpm"

Then install the RPM with this yum command (if you downloaded a different release, substitute the filename here):
