Certificate key usage
How to: use signed certificates in tridium niagara 4
Any public key infrastructure must include digital certificates (PKI). The use and implementation of digital certificates is one of the most difficult topics for engineers to grasp.
Certificate management is the most difficult aspect of PKI implementation. Before you can start managing certificates, you must first understand the basics, such as the different types of certificates, use cases, and the overall process of creating certificate requests. Each of these has a distinct purpose and must be developed in a particular way.

X509v3 has been requested as an extension. Basic Restrictions: CA:FALSE X509v3 X509v3 X509v3 X509v3 Critical Digital Signature, Non-Repudiation, and Key Encryption are examples of key usage. X509v3 is a version of the X509 protocol. Extending TLS Web Client Authentication is a vital application for TLS.

The following is the flow of my program: a client sends a CSR to the server, the server responds with a client certificate, and the client then connects with the server to a route that requires a server-signed certificate (the client certificate)
Caution: Because you tagged SSL, I assume you mean SSL/TLS or something over SSL/TLS (not necessarily HTTP/S) when you say “route that requires a certificate.” If you’re talking about CMS, S/MIME, XML-sig, or even PGP, the response may be different.
Because X.509 (and PKIX) certificates were intended to be used for a variety of purposes, not just SSL/TLS (which is the only use most people are familiar with), this is inevitably broad. It does make a distinction between different kinds of signing, encryption, and key agreement (which in practice is used for encryption).
KeyUsage is only required for CA certs in 5280/3280, implying that it is optional for EE certs. I don’t have the real X.509, but if KeyUsage isn’t present, it’s assumed that all bits are set, which is compatible with v1 and v2 before extensions. It is mandatory for CA certs but optional for “subscriber” (meaning EE) certs, according to the CABforum baseline.

In the CA/Browsers Forum, the Browser participates. The Public CAs are the opposing party. They’re called “the cartel” by others. The “browser security model” or “web app security model” is a security model used by browsers. A collection of predefined trusted anchor points is used in this security model.
The cartel anticipates that end-entity (server) certificates will be signed by a public CA in the browser’s trusted store. Because Chromium uses the Operating System’s trust store, there is some hand waving with “bring around.”
Extended Key Usage is optional, according to RFC 5280. The CA/Browser Forums Baseline Requirements is the other standard, and it is the policy followed by most Public CAs when issuing certificates. Because it is so convoluted, I can’t know what the CA/B BR says about end entity certs.
You’d use keyAgreement if you had a certificate with Diffie-Hellman parameters. I’ve never seen Diffie-Hellman signatures (I believe that’s ElGamal signing), so I don’t think a certificate with Diffie-Hellman parameters should include digitalSignature.

X.509 is a cryptographic standard that specifies the format of public key certificates.
Ssl and certificates explained for beginners
1st Many Internet protocols use X.509 certificates, including TLS/SSL, which is the foundation for HTTPS, the secure web browsing protocol. Offline applications, such as electronic signatures, also make use of them. A public key and an identity (a hostname, an organization, or an individual) are contained in an X.509 certificate, which is either signed by a certificate authority or self-signed. When a certificate is signed or validated by a trusted certificate authority, the public key contained in the certificate may be used to establish secure communications with another party or to validate documents digitally signed by the corresponding private key.
Certificate revocation lists, which are a way to distribute information about certificates that have been considered invalid by a signing authority, are also defined in X.509, as is a certification path validation algorithm, which allows certificates to be signed by intermediate CA certificates, which are then signed by other certificates, ultimately reaching a trust anchor.
