I am using java's KeyTool to generate a self-signed certificate. Just wanted to know if there is a way to create a self signed certificate with a Private Key that has no password.
I know OpenSsl does allow you to do that.

We have an Azure Function (.NET 4.7.2) running for a year that sends messages to a webservice using a client certificate. This certificate has to be renewed but now we have done that we are getting this exception when sending a message;
System.Security.Cryptography.CryptographicException: Invalid provider type specified.
Azure has problems reading the private key and the problem seems to be exporting it from my local machine. Could this problem originate from the original CSR? The previous certificate still works fine, as long as it's valid. Note that I can send messages using the new certificate from my local machine.
Things I have tried;
Using all combinations of MMC settings to export the .pfx file
Using the answer in https://stackoverflow.com/a/34103154/6033193 to convert the cert key to the RSA format and upload the new resulting .pfx
Using CertUtil.exe -store -user my to compare the new and the old certificate. They both have Provider Microsoft Enhanced Cryptographic Provider v1.0 and, apart from the hashes and names, look the same.
Removing Azure Key Vault from the setup and uploading the pfx directly to the app service
Reading the .pfx from a local folder and using it like this: new X509Certificate2(certByes, "password", X509KeyStorageFlags.PersistKeySet);. This works so something seems to be going wrong when uploading the .pfx file to the Azure portal.
Any more things I can try?
The provider that worked for the previous certificate no longer works for the new certificate. I have a hunch something is wrong with the encryption because the Bag Attributes contained no LocalKeyID information, but I cannot say for sure.
Anyway, changing the provider to "Microsoft Platform Crypto Provider" made the private key accessible in Azure. Using OpenSSL:
First export the .key and the public .pem part from the .pfx file;
openssl pkcs12 -in cert.pfx -out cert_publicpart.pem -nokeys
openssl pkcs12 -in cert.pfx -out cert_privatekey.key -nocerts
If it's encrypted it will ask for your password after each command.
Then, convert it back to a .pfx specifying the provider;
openssl pkcs12 -export -in cert_publicpart.pem -inkey cert_privatekey.key -out cert_newCSP.pfx -CSP "Microsoft Platform Crypto Provider"
Again, specify a password and the new .pfx should be good to go!
Optional, if you'd want to verify the CSP:
openssl pkcs12 -in "cert_newCSP.pfx" -out "cert_newCSP.pem"
Open the .pem file, find -----BEGIN ENCRYPTED PRIVATE KEY----- and look for Microsoft CSP Name: Microsoft Platform Crypto Provider right above that.
I am trying to add a HTTP Action that uses Client Certificate authentication to a logic App
When I specify the PFX file that I have generated, I get an error stating
The provided authentication certificate is missing the private key. The private key is required to sign the request.
I am using the portal directly not code
I do have the private key
How do I specify this?

The provided authentication certificate is missing the private key. The private key is required to sign the request.
You are receiving this error because it is missing a private key. You cannot use Client Certificates for authentication without a private key.
On the Client, the Client Certificates must have a Private Key. If absent, then the certificate is ignored. For more information on this, you can refer Here
While Client certificate Import/Export you need to check the box which will provide us the private key.
Alternate:
Sometimes .pfx gile will not work directly. Use OpenSSL to convert them to a .pem, then back to a pfx to get it to work:
openssl pkcs12 -in certificate.pfx -out certificate.pem
openssl pkcs12 -in certificate.pem -export -out certificate2.pfx
The pfx file will work within Azure logic apps when converted to a base64 string. When the pfx file is imported into the Certificates MMC try exporting again and it works.

i am trying to work with docusign JWT.
The environment where i develop only supports .p12 files. Docusign offers me a pem file. Is there a way to convert the .pem into a .p12 or even better to generate a .p12 directly from docusign ?
When trying to convert it to a .p12 i need the certificates. Can anybody help me on where i can get the corresponding / matching certificates ? I am completely lost.
Thanks!

Procedure
Go to https://www.openssl.org/community/binaries.html
Download and install version 1.0.1p.
Run the following command format from the OpenSSL installation bin folder.
openssl pkcs12 -export -out Cert.p12 -in cert.pem -inkey key.pem -passin pass:root -passout pass:root
(original source)
However, you only need the private key to get a token using JWT.
.p12 files include both.
If you can extract the private key from them - you can use it. DocuSign doesn't provide
an SDK support to work with a .p12 file, but there are things in the web you can look into:

I have a key and csr generated and want to use the csr to generate certificates. GoDaddy has a provision wherein the csr can be uploaded for the cert to be generated and am wondering what equivalent openssl command is run to convert csr to cert?
The openssl commmand is:
openssl x509 -signkey GoDaddy.key -in domain.csr -req -days 365 -out domain.crt
Note that it is not a conversion of the csr into a certificate, it is a generation of a certificate from a csr and a private key. The key is always needed. The fact that you don't send your key to GoDaddy is because it's YOUR private key (as pointed out in the comments) and because they sign your certificate with their own private key. That's what makes it special. That's why they are paid for.
In this link you can find some useful openssl commands that may help you in the future.
I have a problem on installation SSL certificate in IIS 7.
I downloaded the ssl certificate from godaddy. I got zip file and I saw two certificate files with .crt and .p7b in zip file.
I tried to install SSL certificate using Complete Certificate Request in IIS. After I installed it, I refreshed the server. When I checked the certificate I installed, it is disappeared in certificate list.
I followed the instructions from godaddy support link.
I tried many ways to install the certificates but after refreshed, it is gone.
I found a way that it needs to import certificate using import under action in IIS, but it needs .pfx file.
I would like to know how do I change from two certificates (.crt and .p7b) to .pfx file.
Actually, I am not familiar with SSL. So, I appreciate your help. Thanks.
You may not be able to convert/export .crt/p7b file to pfx as it doesnt contain private key.
Create a new CSR using DigiCert Utility (http://www.digicert.com). Have your CA issue out the domain cert again with the new CSR.
Then import the crt file in the utility. To enable the option of exporting out a PFX file (which includes both the domain cert and the private key).
openssl pkcs12 -export -out example.com.pfx -inkey example.com.key -in example.com.crt -certfile Example-CA-BUNDLE.crt
A PEM encoded cert and private key can be combined into PKCS12 easily with OpenSSL on the command line.
