In case you are approved for a certificate renewal here is how you do it:
The web server SSL certificates from startssl is free for class 1 and needs to be renewed every year. Two weeks
before SSL certificates expiration, you will receive an email
notification. But you need to validate your email first as email
validation only for 30 days. (Go to control panel in www.startssl.com, click Authenticate, click validations Wizard, and click email validation).
You may also need to renew S/MIME authenticate certificate, which is
only valid for one year. If you fail to renew, you may not enter you
your account. (Go to control panel in www.startssl.com,
click Authenticate, click Certificate Wizards, and click renew S/MIME
Now you can renew your web server SSL. Go to control panel in www.startssl.com, click Authenticate, click Certificate Wizards, and click Web Server SSL/TSL Certificate, following the instruction, copy and save in ssl.key. run the following command
openssl rsa -in ssl.key -out ssl.key
You can also click Decrypt Private Key in Toolbox, which is identical to
the above command. If you have a copy and paste error (for example I
missed a dash - at the first line), you will get the following error
"unable to load Private Key
15632:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:647:
Expecting: ANY PRIVATE KEY"
In this case, you have to create a new certificate by either requesting
revocation (which isn't free of charge) or use a different sub domain.
Click Retrieve Certificate in Toolbox to get ssl.crt Click StartCom Root CA (PEM encoded) in StartCom CA Certificates (left menu) to get ca.pem; Click Class 1 Intermediate Server CA in StartCom CA Certificates (left menu) to get sub.class1.server.ca.pem.
Install your ssl.key, ssl.crt, ca.pem and sub.class1.server.ca.pem in your web server ssl directory and restart your web server.
To check your ssl in your web server, go to SSL checker and input your https website or left click your mouse in your browser
with your https website, click more information and view certificate.
