I have the following files
server.csr
serverprivate.key
serverpublic.key
Provided by vendor: vendor.pem
I need to convert the certificate to a .p12 files and tried the following command via openssl
openssl pkcs12 -export -out esim.p12 -inkey private.key -in ca-preprod.crt
and i'm getting "NO CERTIFICATE MATCHES PRIVATE KEY"
How to generate a .p12 file using the files I have now?
There is a way to import a .pfx certificate in postman?
I need to send a user certificate for testing my API.
At the time of writing this answer Postman didn't support .PFX files. Ref:
Feature Request: Support for PFX
However you can extract cert and private key from the .PFX file using openSSL and configure those in Postman.
Extract key:
openssl pkcs12 -in pfxfile.pfx -nocerts -out key.pem -nodes
Extract cert:
openssl pkcs12 -in pfxfile.pfx -nokeys -out cert.pem
Postman Canary Update has support for PFX Files now. You may use that build instead.
I am trying to convert an Apple Push Certificate (received in .pem format from https://identity.apple.com/pushcert/) to PKCS12 on a Windows machine. I have OpenSSL installed.
Here are the steps I am trying:
Generate CSR
openssl req -out d:\cert\request.csr -new -newkey rsa:2048 -nodes -keyout d:\cert\csrPrivateKey.pem
Upload signed CSR to Apple and download issued certificate (pushCert.pem)
Convert .pem certificate to pkcs12
openssl pkcs12 -export -in d:\cert\pushCert.pem -inkey d:\cert\csrPrivateKey.pem -out d:\cert\pushCert.p12 -name "apns-cert"
When I try this last step, I get an error "No certificate matches private key" and an empty file is created. If anyone has any suggestions it would be greatly appreciated.
Thanks!
I have one .key file from which I generated a .csr file that I used to purchase a GoDaddy code signing certificate. From GoDaddy I received one .spc file.
I exported the spc file to pem with the following command:
openssl pkcs7 -inform DER -in mycert.spc -print_certs -out certs.pem
I then opened the certs.pem file and copied the first two certificates to a file called cert-chain.crt and the last one (which is mine) to one called server.crt.
I tried to sign the file like with this command:
openssl smime -sign -in a.mobileconfig -out signed_a.mobileconfig -signer cert/server.crt -inkey cert/ios_apn.key -certfile cert/cert-chain.crt -outform der -nodetach
But what I got is:
unable to load certificate
11911:error:0906D06C:PEM routines:PEM_read_bio:no start line:/SourceCache/OpenSSL098/OpenSSL098-41/src/crypto/pem/pem_lib.c:648:Expecting: TRUSTED CERTIFICATE
What am I doing wrong? How should I normally sign the a.mobileconfig file with the provided SPC file?
Your certificate is in DER format, but openssl is assuming PEM format. You should add -inform der to the command:
openssl smime -sign -in a.mobileconfig -out signed_a.mobileconfig -signer cert/server.crt -inkey cert/ios_apn.key -certfile cert/cert-chain.crt -inform der -outform der -nodetach
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.spc certificate from GoDaddy.
Export a PEM-formatted private key from the expired PFX:
openssl.exe pkcs12 -in CodeSign.pfx -nocerts -out CodeSign.pem
Convert the PEM-formatted private key into the PVK format:
pvk.exe -in CodeSign.pem -topvk -strong -out CodeSign.pvk
Combine the PVK and SPC into PFX:
pvk2pfx.exe -pvk CodeSign.pvk -pi <passphrase> -spc CodeSign.spc -pfx CodeSign.pfx -po <passphrase> -f
Import 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 or another direct download link here)
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.
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.pem
Create PFX
openssl pkcs7 -in CodeSign.spc -inform der -print_certs | openssl pkcs12 -export -inkey CodeSign.pem -out CodeSign.pfx
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
For anyone still looking for an answer on how to do this, I just spent a day figuring this out and had to do a mix of things listed in this post. If you are using git-bash on windows, I had to add winpty to the beginning of all calls using openssl or else it would get stuck in the void. The pseudo steps were as follows:
Generate a private key and CSR using openssl
openssl req -newkey rsa:2048 -keyout private.key -out my.csr
Generate a PVK using the private key with openssl
openssl rsa -in private.key -outform PVK -pvk-strong -out codesign.pvk
Use the CSR in the generation of the code sign certificate on Godaddy
Download the Zip from Godaddy and extract the SPC file (as mentioned by OP)
Use pvk2pfx to combine the PVK and the SPC file into a code sign certificate. This was included in the same SDK (and directory) as signtool itself:
pvk2pfx.exe -pvk codesign.pvk -spc SPC_FILEPATH_HERE -pfx codesign.pfx -pi PVK_PASSWORD -po PFX_PASSWORD
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
