I have a CA pairkey and I need to sign a client pairkey for client authentication. I am using keytool for this. Based on this I have created a .p12 pairkey for my client. Then I create a CSR and then I sign it to have a .cer file.
My problem is that I want to "update" the cert in the p12 with this signed certificate. Basically, I need to import the keypair into the Personal Certificates for client authentication, but Windows will accept the p12 (which is not signed) and not the .cer (since it has no private key).
How can I update the p12 with the new signed public cert? Thanks.
NOTE: I prefer not to have any intermediate cert and I don't want to use OpenSSL, I need to use keytool
EDIT - By the way, when I try to import the signed certificate into the .p12 I get a keytool error: java.lang.Exception: Failed to establish chain from reply
EDIT - This link and this link seem to address my problem, but it is using OpenSSL and other tools, not keytool.

I tried to use client certificate for authentication using swift XMPP client but not able to select certificate, although I already import certificate in Window client certificate.
Got below message from the client, click ok to continue exit the window certificate dialog.
You need to install certificate first in the OS then the list will show installed certificate in the system.
To install certificate create pfx certificate formate and double click to install the certificate.
To create PFX
openssl pkcs12 -export -out my_certs.pfx -inkey example.com.key -in example.bundle.pem -certfile ca.pem
I am new to this concept of SAML certificates.
I am currently working on configuring an SSO for a website and need to know how I can generate a SAML certificate? The setup I am using for this website is not via Azure, but directly from the vendor site and they are requesting my SAML certificate. Do I need a special tool to do this? and does it need to be registered before sending it out?
Run the command below to create the certificate
e.g:
keytool -genkey -alias saml -dname "CN=mydomain.com, C=NO" -keystore saml-keystore -keyalg RSA -validity 730 -keysize 1024
Send the public certificate to the SAML Consumer party
The SAML Consumer needs to know the public part of your certificate. You may export the public part of the certificate and send this.
keytool -export -rfc -keystore saml-keystore -alias saml -file saml-cert.public
Here is whole details also it, Also there is some other online tool which helps in create certificate online like samltool
There's no such thing as SAML certificate. SAML uses self-signed X.509 certificates that can be generated manually using the openssl. There are number of tutorials on the web how to create such certificate.
Some identity provider will generate the public key and certificate for you.
Keycloak does this and will allow to copy it in the Realms settings.
I'm trying to use Insomnia with Client Certificates. I followed this document from the Insomnia documentation. I added my certificate pem files and password.
The problem is that I'm still getting this error:
Error: Couldn't connect to server.
Do you have any idea why? Thanks.
Insomnia seems rather strict in the rules to apply the client certificate.
For example, if you connect to localhost:5050 you should put localhost:5050 as the host. Localhost as such does not work in this case.
Key + Certificate is also the safest way to get working results. I've noticed a number of cases where the encapsulated certificates (PFX) didn't work but the key + certificate file did. I assume that this is related to the way the pfx-certificates are created because it also applies for the browsers I test with.
I was able to consume an extremely and rare service using insomnia version 2021.4.1. I could not consume it with Soapui nor Postman.
I followed these easy steps. It worked at first attempt :D, just the p12 file was enough on my case.
Importing Certificates with Insomnia
I will put here the official documentation, in case the link disappears:
Insomnia supports PFX (Mac), and PEM (Windows and Linux) certificates. To import a new certificate, open the Document/Collection Settings dialog – accessible from the top-left menu – and click on the Client Certificates tab. From here, you can add new certificates and view existing ones.
Now lets walk through how to import one.
If you’re familiar with client certificates, the only field needing explanation should be the Host field.
Host: certificate will be sent when the host (and port if specified) matches
PFX: certificate in PFX or PKCS12 format (Only supported on Mac)
CRT File + Key File: certificate and key pair (only supported on Windows and Linux)
Passphrase: An optional passphrase for the certificate if required
After importing a certificate, it will show up in the main certificates list. From here, it can be enabled/disabled or deleted.
Insomnia is very strict about self-signed certificates.
I had a similar issue on a Windows environment with Insomnia version 2022.2.1.
My solution was to add the intermediate and root certificates as well to the client certificate (.crt) file with the following order:
-----BEGIN CERTIFICATE-----
client cert
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
intermediate cert
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
root cert
-----END CERTIFICATE-----
Then I imported the client certificate .crt file and .key file for the host and it worked.
I was working on a sample TLS client/server program to perform certificate validation.
For a self signed certificate validation, these are the steps i followed.
#server side:
Generated a server key file serverkey.key
Generated a CSR certificate servercert.csr from the key file.
Digitally signed(using openssl x509 utility) the servercert.csr using a
generated rootCA.key and rootCA.cert. server certificate file servercert.cert
is generated.
Loaded the certificate file(servercert.cert) and key file(serverkey.key) using
SSL_CTX_use_certificate_file and SSL_CTX_use_PrivateKey openssl apis.
#client side:
Loaded the server ca-file --> rootCA.cert (which was manually copied to the
client) using the SSL_CTX_load_verify_locations api.
Using the SSL_get_verify_result() api validated the certificate that server
sends in the Certificate message.
The question that i have is that if i use a trusted CA(like godaddy) to sign a server CSR certificate, will the CA be providing its public key file (something similar to rootCA.cert) as well which was used for signing ?
By which i can load the same to the trusted list at client side using SSL_CTX_load_verify_locations api.
My intention is to keep the code unchanged regardless of being a self signed certificate or a valid CA provided certificate.
When (any) x509 certificate is generated, these things happen:
Private key is generated
Public key (associated with the private key mentioned above) is embedded in the new certificate (becomes an integral part of it)
The new certificate is signed using private key of the issuer (read: CA)
In order to verify the certificate integrity (to check if nobody tampered with it) - you need to verify the signature (created using issuer's private key - see 3)). To be able to do it you need to obtain (somehow) the issuer's public key. This key is embedded in the issuer's certificate (see 2)). Usually the trusted CAs' certificates are stored in so called trusted certificate store. In case of OpenSSL you specify this "store" by using SSL_CTX_load_verify_locations function (and a few other simmilar functions - consult OpenSSL documentation).
To summarize:
In your case the location pointed by SSL_CTX_load_verify_locations should contain your CA's certificate(s) - all of them - the whole certificate chain up to the self-signed root certificate. You can obtain all of the certificates in the chain from your CA (in your case GoDaddy).
I hope that helps.
If I can clarify anything more please ask.
I'm using a self signed certificate for a number of SSL connections. However I have one connection that needs the cert to be CA authenticated.
Now if I use the same self signed certificate and create a certificate authority request
and import what I receive, will anything have to change on my existing direct trust SSL connections ?
what exactly will having the cert CA verified change ?
If anyone has the same question. The answer is that the certificate signing request is used by the CA to generate a public key. This can then be used on the server as a CA verified cert.
Typically your application / server should have a location / import operation for this.
