If you have a pkcs12 file (from IIS for example) and if you need to install the certificate on an Openssl-compatible product such as Apache, you will have to extract the content of the pkcs12 to get several files.

Btw if someone wants to sign the cert.csr hisself, then one could use openssl x509 -req -in cert.csr -signkey key.pem -out cert.crt and then openssl pkcs12 -export -in cert.crt -inkey key.pem -out cert.p12. No need to use the additional command from the answer. – Tom Dec 2 '15 at 13:21. How exactly would I generate a.key file and a.crt file from a.p12 file?

Generate Cert And Key From P12

First of all, create a global file (package):Then duplicate that package file to get 3 different files:Edit each of those files via a test editor. Warning: You need to use a text editor that can interpret OpenSSL-style end-of-lines (under Windows, use an editor compatible with UNIX):

• in mykey.key only keep the 'PRIVATE KEY' bloc
• in mycert.cer only keep the 'BEGIN CERTIFICATE' bloc, corresponding to your server certificate (you know it by reading the comment that appears just above)
• in mychain.txt only the 'BEGIN CERTIFICATE' bloc(s) other than your server certificate (you know it by reading the comment that appears just above)

Those 3 files are usable (even if you might need to convert them into a format compatible with your SSL server)!
Warning: If you create your pfx on Microsoft, do not activate the 'enhanced security'!

Howto convert a PFX to a seperate .key/.crt file

In this article I’m going to show you the commands you need to convert your .PFX Certificate file to a seperate certificate and keyfile. This article can come in handy when you need to import your certificates on devices like Cisco routers/loadbalancers etc. where you probably need to import the certificates and keyfiles in plain text (unencrypted). My tool of choice (but there might be others) is OpenSSL for Windows, which can be downloaded here

Generate Crt From P12

So after you installed OpenSSL you can start it from it’s Bin folder. I’d like to put OpenSSLBin in my path so I can start it from any folder. Fire up a command prompt and cd to the folder that contains your .pfx file. First type the first command to extract the private key:

openssl pkcs12 -in [yourfile.pfx] -nocerts -out [keyfile-encrypted.key]

What this command does is extract the private key from the .pfx file. Once entered you need to type in the importpassword of the .pfx file. This is the password that you used to protect your keypair when you created your .pfx file. If you cannot remember it anymore you can just throw your .pfx file away, cause you won’t be able to import it again, anywhere!. Once you entered the import password OpenSSL requests you to type in another password, twice!. This new password will protect your .key file.

Now let’s extract the certificate:

openssl pkcs12 -in [yourfile.pfx] -clcerts -nokeys -out [certificate.crt]

Just press enter and your certificate appears.

Now as I mentioned in the intro of this article you sometimes need to have an unencrypted .key file to import on some devices. I probably don’t need to mention that you should be carefully. If you store your unencrypted keypair somewhere on an unsafe location anyone can have a go with it and impersonate for instance a website or a person of your company. So always be extra careful when it comes to private keys! Just throw the unencrypted keyfile away when you’re done with it, saving just the encrypted one.

The command:

openssl rsa -in [keyfile-encrypted.key] -out [keyfile-decrypted.key]

Again you need to enter an import password. This time you need to enter the new password that you created in step 1. After that you’re done. You decrypted your private key. In the folder you ran OpenSSL from you’ll find the certifcate (.crt) and the two private keys (encrypted and unencrypted).

In some cases you might be forced to convert your private key to PEM format. You can do so with the following command:

Create Crt And Key From P12

openssl rsa -in [keyfile-encrypted.key] -outform PEM -out [keyfile-encrypted-pem.key]Windows 7 key.

Good Luck!
