In this article we will use the OpenSSL library to create a PKCS#12 Keystore from an existing Private Key & Certificate. This demonstration uses MacOS but the same steps can be followed on other operating systems that support OpenSSL.

Navigate to the directory where the certificate and private key is stored and enter the following commands (replacing anything in < > if file names are different).
- keystore.p12 = the name of the PKCS#12 file

openssl pkcs12 -export -in <certificate.crt> -inkey <private.key> -name 'tomcat' -out keystore.p12

The PKCS#12 file has been generated in the same directory as the private key and certificate.
