问题
I have a GoDaddy-issued code signing certificate in a .spc file. Also, I have a private key in .key file. The code signing has been issued some 13 months ago, then it expired and was renewed with GoDaddy. During the renewal process no private key was requested and just a new .spc file was issues.
Now I'm facing the problem of joining the original private key file with the issues certificate to form a .pfx (or .cer?) file suitable for installation into the Windows certificate store.
The command I'm trying is:
openssl.exe pkcs12 -inkey my.key -in my.spc -out my.pfx -export
However, I'm getting an error message that reads “No certificate matches private key”.
I've followed this answer on SO to verify the .key file is a valid private key. However, when I try to verify that .spc is a valid certificate, I just get
unable to load certificate
5436:error:0906D06C:PEM routines:PEM_read_bio:no start line:.\crypto\pem\pem_lib.c:650:Expecting: TRUSTED CERTIFICATE
What's the correct way of producing an .pfx file from my inputs? I'm using OpenSSL 0.9.8k.

In the end I managed to figure out a procedure that works. Here are the steps to generate a new PFX and CER code signing certificate from SPC and KEY files:
- Obtain your new
CodeSign.spccertificate from GoDaddy. Export a PEM-formatted private key from the expired PFX:
openssl.exe pkcs12 -in CodeSign.pfx -nocerts -out CodeSign.pemConvert the PEM-formatted private key into the PVK format:
pvk.exe -in CodeSign.pem -topvk -strong -out CodeSign.pvkCombine the PVK and SPC into PFX:
pvk2pfx.exe -pvk CodeSign.pvk -pi <passphrase> -spc CodeSign.spc -pfx CodeSign.pfx -po <passphrase> -fImport the resulting PFX file into Windows certificate store. Remember to make it exportable.
- Export it from the certificate store into the binary CER format as
CodeSign.cer. - Optionally delete the certificate from the Windows certificate store.
In case you are renewing your certificate periodically you can store the PVK file and skip steps (2) and (3).
UPDATE: In case you happen to have the certificate in CRT instead of SPC format, do the following to covert it into SPC:
openssl crl2pkcs7 -nocrl -certfile CodeSign.crt -outform DER -out CodeSign.spc

The tools you will need:
- OpenSSL
- pvk.exe — see the download link at the bottom of that page (original location may not be accessible; in such a case see this article with a link to a mirror site)
- pvk2pfx.exe — part of Microsoft SDKs, installs with Visual Studio 2010

I had the similar issue and I spent at least few hours searching around for a solution. GoDaddy provided me with .spc and .pem file and I couldn't create .pfx file out if it using OpenSSL. Finally, I imported .spc file within my local computer using MMC. Once the certificate was imported in my local machine, I noticed that it brought in GoDaddy's chain file along with the Code Sign Cert file itself. MMC View
Now, select both files and right click to export as .pfx file. Supply a password to protect the file and you're done. By far, this is the simplest and straight forward solution. Hope this post helps many people.

The current answer post was extremely helpful to me in the final steps of moving from an expired certificate file (.pfx or .p12) to a new one with GoDaddy, but I found it lacking information on the initial steps of how to generate a certificate signing request (CSR) from my original certificate file.
For anyone else looking for similar information, here is what I ended up using...
Get the private key:
openssl pkcs12 -in certs-and-key.p12 -out privateKey.key
Get the certificatate:
Beware: This can give you the CA cert
openssl pkcs12 -in certs-and-key.p12 -out certificate.crt -nokeys
Better: Use this command to print only the client cert
openssl pkcs12 -in MacCossLabUW.p12 -clcerts
Then copy the output between:
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
Save it to a file named certificate.crt
Now check that the private key and certificate match with the commands:
openssl rsa -noout -modulus -in privateKey.key | openssl md5
openssl x509 -noout -modulus -in certificate.crt | openssl md5
Then generate a new CSR:
openssl x509 -x509toreq -in certificate.crt -out CSR.csr -signkey privateKey.key
Use the CSR to Re-Key the certificate.
Download the GoDaddy software publishing certificate (.spc) file.
Verify that the generated certificate matches the request private key:
openssl pkcs7 -inform DER -in certificate.spc -print_certs
Then copy the output between for your certificate (Note: the output will also contain CA certs):
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
Save to a file named certificate-new.crt
And run the command:
openssl x509 -noout -modulus -in certificate-new.crt | openssl md5
The output should match the previous call used with the private key and request certificate.
To finish the process, follow the steps outlined in the answer with pvk2pfx.
I also found the schematic diagram in this post quite helpful:
PVK2PFX Error 0x80070490 - Cannot find certificates that match the key

You can create PFX with openssl only.
Export a PEM-formatted private key from the expired PFX:
openssl pkcs12 -in CodeSign.pfx -nocerts -out CodeSign.pemCreate PFX
openssl pkcs7 -in CodeSign.spc -inform der -print_certs | openssl pkcs12 -export -inkey CodeSign.pem -out CodeSign.pfx

If you generated your certificate request from IIS (I did this on IIS on windows 2012 Server) follow these steps on the server/pc where you generated the request - Open IIS - Click on the top level node (Server node) - Open the Server Certificates settings - Click on "Complete certificate request" under actions on the right - Import your spc file to the server.
From here you can then export to a PFX file
