We like to access a webserver using client certificate authentication instead of basic authentication. Certificate is a PEM cert and the key file is a separate file. The curl call looks like this:

Before using client authentication, make sure the client has a valid public key certificate. For more information on creating and using public key certificates, read Working with Digital Certificates. The following example shows how to declare client authentication in your deployment descriptor: CLIENT-CERT

Mar 02, 1998 · Client authentication is a nifty feature that lets you authenticate users who are accessing the server by exchanging a client certificate -- this means no more "Anonymous" entries appearing in the User Activity log of a database when accessed by an Internet user.

Jul 17, 2020 · Client Certificate Authentication is disabled (the default). BIG-IP never sends Certificate Request to client and therefore client does not need to send its certificate to BIG-IP. In this case, TLS handshake proceeds successfully without any client authentication: pcap: ssl-sample-peer-cert-mode-ignore.pcap Feb 29, 2020 · Certificate-based Authentication is the use of a Digital Certificate to identify a client request before granting it the access to a resource, network, application, etc. Certificate Authentication provides added security to web applications. You can easily implement it in ASP.NET Core 3.0. Let us understand how to do it. Apr 19, 2018 · After you replace an expired certificate with a new certificate on a server that is running Microsoft Internet Authentication Service (IAS) or Routing and Remote Access, clients that have Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) configured to verify the server's certificate can no longer authenticate with the server.

Aug 15, 2017 · The Certificate Revocation List (CRL) is key to making this security approach work with many users. Without the CRL, should a certificate become compromised you would need to re-issue the Certificate Authority (CA) and any client certificates.

Jun 20, 2013 · When client authentication is used, the server still sends its certificate to the client, but it also sends a "Certificate Request" message to the client. This lets the client know that it needs to get its certificate ready because the next message from the client to the server (during the handshake) will need to include the client certificate. You can configure a client certificate to authenticate users first and then require users to log on with a secondary authentication type, such as LDAP or RADIUS. In this scenario, the client certificate authenticates users first. Use the client’s private key to generate a cert request. openssl req -new -key client.key -out client.req; Issue the client certificate using the cert request and the CA cert/key. openssl x509 -req -in client.req -CA ca.cer -CAkey ca.key -set_serial 101 -extensions client -days 365 -outform PEM -out client.cer Client-certificates only provide you with authentication. You may still need to get further attributes (e.g. from LDAP or a database against the certificates' subjects). You will certainly need to have an authorisation logic on top of this, as it would be for any other authentication system.
