How To Create A Java Keystore Containing A Self Signed Certifate Generated With OpenSSL

A small shell script to generate a private key, a self signed certificate using OpenSSL and finally importing them into a Java keystore. A self signed certificate is usually used during development and test phases, so to make your life easier, the key created is not protected by password. The .p12 file being created by openssl is password protected because lot of users reported that otherwise keytool would refuse to import it. The self signed certificate will expire after 9999 days, I hope it is enough time to complete your development.

# generating private key without password
openssl genrsa -out server.private.key 2048

# generating a certificate signing request
openssl req -new -key server.private.key -out server.csr -subj "/C=IT/ST=Milan/L=Milan/O=MyOffice/OU=IT Department/CN=mywebsite"

# self signing the certificate
openssl x509 -req -days 9999 -in server.csr -signkey server.private.key -out server.crt

# including private key and certificate to a pkcs12, needed to import them into a keystore
openssl pkcs12 -export -in server.crt -inkey server.private.key -out server.p12 -name mywebsite -CAfile ca.crt -caname root -password pass:pazzword

# importing it into a newly created Java keystore
keytool -importkeystore \
        -deststorepass pazzword -destkeypass pazzword -destkeystore keystore \
        -srckeystore server.p12 -srcstoretype PKCS12 -srcstorepass pazzword \
        -alias mywebsite


Pure CSS3 Ribbon

Have you ever wanted your site to sport a “ribbon” in the upper right corner ?

You can easily do it using CSS3. Start with a simple DIV element that will define the ribbon content.

<div>CSS3 Ribbon</div>

Then let’s start applying some styles through CSS. First of all, let’s detach the element from the document flow and let’s put it in the top right corner.

right: 0px;
top: 0px;

Then we should rotate it by 45 degrees clockwise, as every banner actually is. Let’s use transform and transform-origin along with all the needed browser translations of this not yet unanimously supported attributes.

-moz-transform-origin: 50% 50%;
-moz-transform: translate(90px,30px) rotate(45deg);
-webkit-transform-origin: 50% 50%;
-webkit-transform: translate(90px,30px) rotate(45deg);
-o-transform-origin: 50% 50%;
-o-transform: translate(90px,30px) rotate(45deg);
transform-origin: 50% 50%;
transform: translate(90px,30px) rotate(45deg);

Then we add some style to the banner itself.

color: white;
background: #119911;
border: 10px white double;
padding: 10px;

This is the live demo.

Hope you enjoy it.
