DevOps

As a developer, I LOVE my geeky t-shirts and mugs, but it's hard to find quality products with designs I like. I've therefore been hard at work these last few weekends putting together my new project: www.moderngeekware.com

PKCS#12 archives (commonly known as .pfx files) usually contain both a certificate and its private key, sometimes with password protection. In order to use these with a server like nginx or Apache, we need to extract these objects and convert them using openssl.

(The commands below assume your file is named certificate.pfx.)

Extracting the private key

openssl pkcs12 -in certificate.pfx -out private.key -nocerts -nodes
