![]() ![]() For testing this scenario, we use a password protected PFX-encoded file – certificatepfx.pfx and a 2048-bit RSA private key. We use an OpenSSL toolkit to convert a PFX encoded certificate to PEM format. privatekeyconvert.pem – PEM file containing the private key of the certificate with no password protection.certconvert.pem – PEM file containing the SSL/TLS certificate for the resource.The following procedure will convert the PFX-encoded certificate file into two files in PEM format. ![]() The following file extensions are possible for PEM certificates:*.pem, *.crt, and *.cer How to convert PFX file to PEM format? Scenario 1: Export private key and certificate files from PFX file PEM is a base64 encoded certificate placed between the headers -–BEGIN CERTIFICATE-– and -–END CERTIFICATE-–. The file can also include CA chain certificates as well. pfx file is a bag that can hold many objects with optional password protection however, a PKCS#12 archive usually contains a certificate and the corresponding private key. The filename extension for PKCS #12 files is. intermediate certificates), then converting the file to PKCS12 is simple: openssl pkcs12 -export -in clientprivcert.pem -out clientprivcert.pfx. PKCS #12 is an archive file format used for storing multiple cryptography objects in a single file. output of certbot -version or certbot-auto -version if you're using Certbot): certbox 1.22.Reading time: 3 minutes What is PKCS #12? I'm using a control panel to manage my site (no, or provide the name and version of the control panel): Yes I can login to a root shell on my machine (yes or no, or I don't know): Yes The operating system my web server runs on is (include version): Ubuntu 20.04 Exporting a Certificate from PFX to PEM Open a Windows command prompt and navigate to Opensslbin. It produced this output: A PFX file(when importing into Windows it's full chain), but when importing into my software running on Ubuntu I get the errors listed - Chain Not Valid & Key Protection Algorithm not Found. I ran this command: openssl pkcs12 -export -out /home/certificate.pfx -inkey /etc/letsencrypt/live//privkey.pem -in /etc/letsencrypt/live//cert.pem -certfile /etc/letsencrypt/live//fullchain.pem -passout pass:$$$$$$$$$$$$$$$ Resulted file will contain: PKCS8 private key, leaf certificate and all available intermediate CA certificates, including Root CA certificate if applicable. Private key is converted to PKCS8 format. ![]() Just to confirm, the PFX exports, and on Windows it imports perfectly, I just think it's something that is unique to the process that is importing the certificate on this device. In this example, the certificate is retrieved from local certificate store and converted PEM is saved to ssl.pem file. Applications often use different file formats. There are several different file formats that can be used to hold certificates and their private keys each with their own benefits. Verbatim Error is: Caused by: : Key protection algorithm not found: : Certificate chain is not valid openssl crl2pkcs7 -nocrl -certfile CERTIFICATE.pem -certfile MORE.pem -out CERTIFICATE. If you are an Atlas portal user, please submit request to. pfx may be something that isn't supported by the proprietary webserver that ManageEngine uses? Is there a way to change it? And any ideas what I should change it too? It looks like it's using a Java Engine to import the cert: ![]() I'm guessing the algorithm that openssl is using to convert from the. I think the PFX is being built right, but I am seeing an issue in the logs saying Certificate Chain is not Valid & Key Protection Algorithm Not Found. I'm using a platform called Manage Engine Service Desk MSP to run an IT Helpdesk, but I am having an issue getting the SSL certificate into a format that it will take. ![]()
