Problems converting a .PFX certificate to .PEM - ssl

I work with certificates and occasionally need to convert a private certificate .PFX extension for .PEM extension, but I can only consume it in a webservice if it is generated without a password, that is, unprotected.
If I try to generate it with password (being the same password as or not of .PFX certificate), I can not consume it in webservice (I get the error "403 - Forbidden").
Can you tell me why this occurs?
To generate it unprotected, I use the command below (through OpenSSL):
pkcs12 -in certificate.pfx -out certificate.pem -nodes
To generate it with password, I use this one:
pkcs12 -in certificate.pfx -out certificate.pem
I can not understand why the error occurs, since OpenSSL does not indicate a failure.
I use Windows environment, so I use an OpenSSL tool I found on the internet.

Create custom certificate for dynamics portal using certbot/openssl

I need to create a custom certificate for my dynamics portal to use implicit grant flow. I create certificate with command
certbot certonly --manual --preferred-challenge dns
I then create pfx with the openssl command
openssl pkcs12 -export -out bundle.pfx -inkey privkey.pem -in cert.pem -certfile chain.pem -password pass:SOMEPASSWORDHERE
However I get the error when trying to upload it to the power platform admin centre
The password entered is incorrect or the encryption method used by the
certificate is not supported.
So then tried the following command to create the pfx with triple des using
openssl pkcs12 -export -descert -out bundle.pfx -inkey privkey.pem -in cert.pem -certfile chain.pem -password pass:SOMEPASSWORDHERE
But am still getting the same error. As far as I can see the certificate meets requirements of:
Signed by a trusted certificate authority.
Exported as a password-protected PFX file.
Contains private key at least 2048 bits long.
Contains all intermediate certificates in the certificate chain.
Must be SHA2 enabled; SHA1 support is being removed from popular browsers.
PFX file must be encrypted with TripleDES encryption. Power Apps portals doesn't support AES-256 encryption
The only thing I can think is the pfx isn't getting encrypted with 3des but looking at the openssl documentation the -descert command should take care of that. Am I missing something here?

How do I use OpenSSL in the terminal to convert a .pem file to other formats?

I am trying to use OpenSSL in the terminal. I have installed OpenSSL using brew install openssl. I want to convert a .pem file to another format that my hosting provider will accept.
I have tried several different formulations of the code and plying the certificate from different places but none seem to work and all give me various error messages including permission denied.
This is what I tried last...
openssl pkcs12 -in /Users/myname/fullchain.pem -inkey /Users/myname/privkey.pem -out /Users/myname/fullchain.pfx -cacerts
This is my output
4552226412:error:0DFFF0A8:asn1 encoding routines:CRYPTO_internal:wrong tag:/BuildRoot/Library/Caches/com.apple.xbs/Sources/libressl/libressl-22.250.1/libressl-2.6/crypto/asn1/tasn_dec.c:1125:
4552226412:error:0DFFF03A:asn1 encoding routines:CRYPTO_internal:nested asn1 error:/BuildRoot/Library/Caches/com.apple.xbs/Sources/libressl/libressl-22.250.1/libressl-2.6/crypto/asn1/tasn_dec.c:306:Type=PKCS12
What might this mean and what code should I be using?
Edit: I am getting output files but they are of course empty.
That error message is usually when the certificate format you pass to the command is not what it is expecting. The following command should solve it for you.
openssl pkcs12 -export -out /Users/myname/fullchain.pfx -inkey /Users/myname/privkey.pem -in /Users/myname/fullchain.pem
It should prompt you to enter an export password to encrypt the .pfx files content if it has succeeded.

Cannot create pfx file from cer file with openssl

I'm sure that this has been asked you several times, but solutions to that cases didn't work for me. So I need your help.
Consider x.root.cer is CA's certificate, x.app.cer is Application's certificate signed by CA's certificate, and x.app.private.pem is Application's private key.
I'm using following command in order to create pfx file (want to include both private key and certificate of application).
openssl pkcs12 -export -in x.app.cer -inkey x.app.private.pem -out x.app.pfx -certfile x.root.cer
Even though I know (can see) that 3 files are there, I'm getting the following error:
unable to load certificates
Can you please help me about this error?
Well, finally I suceeded with this command
openssl pkcs12 -export -in x.app.cer -inkey x.app.private.pem -out x.app.pfx
That means I shouldn't use -certfile parameter.

How to create P12 file using openssl

I am having some serious problems with regards to being able to create a p12 file to place on my windows server.
I have used two different websites to be able to help me work out what i need to do:
http://www.raywenderlich.com/32960/apple-push-notification-services-in-ios-6-tutorial-part-1
The second website i used was a comment from within the website was the following:
http://arashnorouzi.wordpress.com/2011/06/19/sending-apple-push-notifications-in-asp-net-and-c-–-part-4-apns-sharp-c-wrapper-class/
First of all i create a Certificate signing request.
I then upload this to my app ID which alows me to generate a ape_dev certificate.
I then go to my key chain and navigate to the "keys" i export the .p12 certificate that i just created.
I now have three different files
My p12 file, my development certificate and my certificate signing request.
I then open terminal and i type the following:
$ openssl x509 -in aps_development.cer -inform der -out PushChatCert.pem
This then creates a new pem certificate.
The thing i type is the following
$ openssl pkcs12 -nocerts -out PushChatKey.pem -in PushChatKey.p12
It prompts for the password which i enter, i use the same password as the one when i created the certificates.
After i have done this I'm left with 2 new files both of which are PEM files.
I need to combine both of these PEM files into one p12 file for it to be able to work on my windows server.
I have tried combining it using the following line
openssl pkcs12 -export \
-in aps_developer_identity.pem \
-out aps_developer_identity.p12 \
-inkey APSCertificates.pem
This in fact works and gives me a p12 file.
I then switched back to he raywenderlich website and i typed the following:
$ openssl s_client -connect gateway.sandbox.push.apple.com:2195
-cert PushChatCert.pem -key PushChatKey.pem
It loads but i recieve the following error:
error:num=20:unable to get local issuer certificate
Please does any one know what im doing wrong im so fed up of going round in circles.
When i upload the certificate to the server and put the ad-hoc version off the application on the device im still not receiving any notifications that i am sending
Thanks in advance.
See if this answer helps Creating .pem file for APNS?
In short: openssl pkcs12 -in apns-dev-cert.p12 -out apns-dev-cert.pem -nodes -clcerts
When you first generated your CSR, you did it with a private key. This can be opaque depending on how you did it. What I do is generate the key with openssl and then make the CSR using that key. That key is then the 'in key' when you make the p12.
Here are my steps
The first step is to generate a Certificate Signing Request. This is the same as it would be for any SSL cert. You will need a private key for this.
openssl genrsa -out aps_development.key -passout pass:foobar 2048
Then you can make the CSR using that key you just created
openssl req -new -key aps_development.key -out CertificateSigningRequest.certSigningRequest -subj "/emailAddress=yourAddress#example.com, CN=John Doe, C=US"
From here you will go to developer.apple.com and revoke the current APN cert and make a new one. It will ask for your CSR and when its done it will give you a .cer file.
Convert the .cer file into a DER formatted .pem file (assuming aps_development.cer is the file you got in the download from the Apple developer site).
openssl x509 -in aps_development.cer -inform DER -outform PEM -out aps_development.pem
Convert the .pem to a .p12. You'll note that you are supplying the key file you made at the beginning of step 1. You will need the password you supplied there.
openssl pkcs12 -export -in aps_development.pem -inkey aps_development.key -out aps_development.p12

How to get .pem file from .key and .crt files?

How can I create a PEM file from an SSL certificate?
These are the files that I have available:
.crt
server.csr
server.key
Your keys may already be in PEM format, but just named with .crt or .key.
If the file's content begins with -----BEGIN and you can read it in a text editor:
The file uses base64, which is readable in ASCII, not binary format. The certificate is already in PEM format. Just change the extension to .pem.
If the file is in binary:
For the server.crt, you would use
openssl x509 -inform DER -outform PEM -in server.crt -out server.crt.pem
For server.key, use openssl rsa in place of openssl x509.
The server.key is likely your private key, and the .crt file is the returned, signed, x509 certificate.
If this is for a Web server and you cannot specify loading a separate private and public key:
You may need to concatenate the two files. For this use:
cat server.crt server.key > server.includesprivatekey.pem
I would recommend naming files with "includesprivatekey" to help you manage the permissions you keep with this file.
I needed to do this for an AWS ELB. After getting beaten up by the dialog many times, finally this is what worked for me:
openssl rsa -in server.key -text > private.pem
openssl x509 -inform PEM -in server.crt > public.pem
Thanks NCZ
Edit: As #floatingrock says
With AWS, don't forget to prepend the filename with file://. So it'll look like:
aws iam upload-server-certificate --server-certificate-name blah --certificate-body file://path/to/server.crt --private-key file://path/to/private.key --path /cloudfront/static/
http://docs.aws.amazon.com/cli/latest/reference/iam/upload-server-certificate.html
A pem file contains the certificate and the private key. It depends on the format your certificate/key are in, but probably it's as simple as this:
cat server.crt server.key > server.pem
Additionally, if you don't want it to ask for a passphrase, then need to run the following command:
openssl rsa -in server.key -out server.key
this is the best option to create .pem file
openssl pkcs12 -in MyPushApp.p12 -out MyPushApp.pem -nodes -clcerts
I was trying to go from godaddy to app engine. What did the trick was using this line:
openssl req -new -newkey rsa:2048 -nodes -keyout name.unencrypted.priv.key -out name.csr
Exactly as is, but replacing name with my domain name (not that it really even mattered)
And I answered all the questions pertaining to common name / organization as www.name.com
Then I opened the csr, copied it, pasted it in go daddy, then downloaded it, unzipped it, navigated to the unzipped folder with the terminal and entered:
cat otherfilegodaddygivesyou.crt gd_bundle-g2-g1.crt > name.crt
Then I used these instructions from Trouble with Google Apps Custom Domain SSL, which were:
openssl rsa -in privateKey.key -text > private.pem
openssl x509 -inform PEM -in www_mydomain_com.crt > public.pem
exactly as is, except instead of privateKey.key I used name.unencrypted.priv.key, and instead of www_mydomain_com.crt, I used name.crt
Then I uploaded the public.pem to the admin console for the "PEM encoded X.509 certificate", and uploaded the private.pem for the "Unencrypted PEM encoded RSA private key"..
.. And that finally worked.
All of the files (*.crt, server.csr, server.key) may already be in PEM format, what to do next with these files depends on how you want to use them, or what tool is using them and in which format it requires.
I'll go a bit further here to explain what are the different formats used to store cryptography materials and how to recognise them as well as convert one to/from another.

This is a gist explains the same thing + commands for conversion/verification/inspection.
In conclusion, typical steps to work with cryptography/PKI materials:
Understand which format they are in (use verification/inspection commands)
Understand which format they are required (read doc)
Use conversion commands to convert the files
Optional: use verification/inspection commands to verify converted files
What I have observed is: if you use openssl to generate certificates, it captures both the text part and the base64 certificate part in the crt file. The strict pem format says (wiki definition) that the file should start and end with BEGIN and END.
.pem – (Privacy Enhanced Mail) Base64 encoded DER certificate,
enclosed between "-----BEGIN CERTIFICATE-----" and "-----END
CERTIFICATE-----"
So for some libraries (I encountered this in java) that expect strict pem format, the generated crt would fail the validation as an 'invalid pem format'.
Even if you copy or grep the lines with BEGIN/END CERTIFICATE, and paste it in a cert.pem file, it should work.
Here is what I do, not very clean, but works for me, basically it filters the text starting from BEGIN line:
grep -A 1000 BEGIN cert.crt > cert.pem
Trying to upload a GoDaddy certificate to AWS I failed several times, but in the end it was pretty simple. No need to convert anything to .pem. You just have to be sure to include the GoDaddy bundle certificate in the chain parameter, e.g.
aws iam upload-server-certificate
--server-certificate-name mycert
--certificate-body file://try2/40271b1b25236fd1.crt
--private-key file://server.key
--path /cloudfront/production/
--certificate-chain file://try2/gdig2_bundle.crt
And to delete your previous failed upload you can do
aws iam delete-server-certificate --server-certificate-name mypreviouscert
Download certificate from provisional portal by appleId,
Export certificate  from Key chain and  give name (Certificates.p12),
Open terminal and goto folder where you save above Certificates.p12 file,
Run below commands:
a) openssl pkcs12 -in Certificates.p12 -out CertificateName.pem -nodes,
b) openssl pkcs12 -in Certificates.p12 -out pushcert.pem -nodes -clcerts
Your .pem file ready "pushcert.pem".
Open terminal.
Go to the folder where your certificate is located.
Execute below command by replacing name with your certificate.
openssl pkcs12 -in YOUR_CERTIFICATE.p12 -out YOUR_CERTIFICATE.pem -nodes -clcerts
Hope it will work!!
On Windows, you can use the certutil tool:
certutil -encode server.crt cert.pem
certutil -encode server.key key.pem
You can combine both files to one in PowerShell like this:
Get-Content cert.pem, key.pem | Set-Content cert-and-key.pem
And in CMD like this:
copy cert.pem+key.pem cert-and-key.pem /b
