AuthenticateAsServer(X509Certificate serverCertificate)

Parameters

• serverCertificate
  An X509Certificate that contains the server's public and private keys.

Note: This overload uses default values for client certificate requirements, enabled SSL protocols, and certificate revocation checking. For more control, use other overloads.

AuthenticateAsServer(X509Certificate serverCertificate, bool clientCertificateRequired, SslProtocols enabledSslProtocols, bool checkCertificateRevocation)

Parameters

• serverCertificate
  An X509Certificate that contains the server's public and private keys.
• clientCertificateRequired
true to require a client certificate; otherwise, false.
• enabledSslProtocols
  A bitwise combination of the SslProtocols values that specifies the protocols to use for authentication.
• checkCertificateRevocation
true to check for certificate revocation; otherwise, false.

AuthenticateAsServer(X509Certificate serverCertificate, bool clientCertificateRequired, RemoteCertificateValidationCallback userCertificateValidationCallback, bool checkCertificateRevocation)

Parameters

• serverCertificate
  An X509Certificate that contains the server's public and private keys.
• clientCertificateRequired
true to require a client certificate; otherwise, false.
• userCertificateValidationCallback
  A RemoteCertificateValidationCallback delegate that provides a callback method to validate the remote certificate.
• checkCertificateRevocation
true to check for certificate revocation; otherwise, false.

AuthenticateAsServer(X509Certificate serverCertificate, bool clientCertificateRequired, SslProtocols enabledSslProtocols, CipherSuitesPolicy enabledSslCipherSuites)

Parameters

• serverCertificate
  An X509Certificate that contains the server's public and private keys.
• clientCertificateRequired
true to require a client certificate; otherwise, false.
• enabledSslProtocols
  A bitwise combination of the SslProtocols values that specifies the protocols to use for authentication.
• enabledSslCipherSuites
  A CipherSuitesPolicy object that specifies the allowed cipher suites.

AuthenticateAsServer(X509Certificate serverCertificate, bool clientCertificateRequired, RemoteCertificateValidationCallback userCertificateValidationCallback, SslProtocols enabledSslProtocols, CipherSuitesPolicy enabledSslCipherSuites)

Parameters

• serverCertificate
  An X509Certificate that contains the server's public and private keys.
• clientCertificateRequired
true to require a client certificate; otherwise, false.
• userCertificateValidationCallback
  A RemoteCertificateValidationCallback delegate that provides a callback method to validate the remote certificate.
• enabledSslProtocols
  A bitwise combination of the SslProtocols values that specifies the protocols to use for authentication.
• enabledSslCipherSuites
  A CipherSuitesPolicy object that specifies the allowed cipher suites.

Remarks

• The AuthenticateAsServer method completes the SSL/TLS handshake. This method must be called before any data is sent or received.
• For the server to be able to authenticate itself, a server certificate must be available. If serverCertificate is null, an ArgumentNullException exception is thrown.
• If the server requires a client certificate, set the clientCertificateRequired parameter to true.
• The userCertificateValidationCallback delegate allows you to customize how client certificates are validated.
• The enabledSslProtocols parameter allows you to specify which SSL/TLS protocols are allowed. It is recommended to use the most secure available protocols.
• The checkCertificateRevocation parameter determines whether to check for certificate revocation. Enabling this check enhances security.
• The enabledSslCipherSuites parameter allows fine-grained control over which cipher suites are permitted for the connection.

Requirements

• Namespace: System.Net.Security
• Assembly: System.Net.Security.dll
