How to create a P7B file

What is a P7B file?

A P7B file is a combination of an SSL Certificate and Intermediate CA Bundle. It is most often used when installing an SSL Certificate onto Windows and Tomcat environments. It is determined with the ‘.p7b’ file suffix.

Using the Trustico® Tool to create a P7b file

What you will need:

Step 1: Trustico® Tools

Open the Trustico® Tools and make sure you are on the ‘SSL Certificate Converter’ page.

The landing page of the SSL Certificate Converter Tool.

Step 2: Upload the SSL Certificate

Click the ‘Choose File’ button under the ‘SSL Certificate To Convert’ option and select the relevant SSL/TLS Certificate (ensure it is in either .cer or .crt format). The tool will attempt to automatically detect the format and update the ‘Existing SSL Certificate Format’ accordingly; if you think this is wrong, simply manually select the format type using the dropdown menu.

Step 3: Choose the file format

Under the ‘New SSL Certificate Format’ option, use the dropdown menu to select ‘P7B/PKCS#7’. This will add some additional forms to fill above.

Step 4: Upload the Intermediate CA Bundle

Click the ‘Choose File’ button under the ‘Intermediate Certificate 1 (Optional)’ option and select your Intermediate CA Bundle (ensure it is in either .cer or .crt format). You can ignore ‘Intermediate Certificate 2 (Optional)’ since we are using a bundle.
