The JWT is signed with the X509 Certificate’s private key, and the connected app uses the certificate to verify the signature. I know you can create a self-signed cert through salesforce but that never gives you a private key. How do you create a self signed x509 certificate that you can upload to salesforce and use with your connected app?. This self-signed certificate also needs a private key otherwise it’s pretty useless for SSL, token signing etc…. openssl req -x509 -newkey rsa:4096 -sha256 -keyout -out openssl. I have a self-signed v3 cert from HP (used for ILO) The Certificate has only ‘one’ extension which is “Subject Alternative Name” I believe the thumb print and thumb print algorithm are store properties rather than extensions. So my point is there is no Key Usage (and thereby no Enhanced Key Usage) extension.

TLS (SSL, x.509) Certificate Generator. tls-gen is an OpenSSL-based tool that generates self-signed x.509 certificates that are meant to be used in development and QA environments.. The project is originally extracted from a number of RabbitMQ test suites.. What It Does. tls-gen generates a self-signed Certificate Authority (CA) certificate and two or more pairs of keys: client and server, all. Digital certificate, x.509. X.509 is a standard format for public key certificates, digital documents that securely associate cryptographic key pairs with identities such as websites, individuals, or organizations. First introduced in 1988 alongside the X.500 standards for electronic directory services, X.509 has been adapted for internet use by the IETF’s Public-Key. Using OpenSSL to generate a self-signed certificate. To generate a new self signed certificate and private key with openssl, run the following command: openssl req -nodes -newkey rsa:2048 -keyout -out -x509 -days 365.
