A complex type that determines the distribution's SSL/TLS configuration for communicating with viewers.

If the distribution doesn't use Aliases (also known as alternate domain names or CNAMEs)—that is, if the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net—set CloudFrontDefaultCertificate to true and leave all other fields empty.

If the distribution uses Aliases (alternate domain names or CNAMEs), use the fields in this type to specify the following settings:

All distributions support HTTPS connections from viewers. To require viewers to use HTTPS only, or to redirect them from HTTP to HTTPS, use ViewerProtocolPolicy in the CacheBehavior or DefaultCacheBehavior. To specify how CloudFront should use SSL/TLS to communicate with your custom origin, use CustomOriginConfig.

For more information, see Using HTTPS with CloudFront and Using Alternate Domain Names and HTTPS in the Amazon CloudFront Developer Guide.

Properties

NameTypeDescription
Public Property ACMCertificateArn System.String

Gets and sets the property ACMCertificateArn.

If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in Certificate Manager (ACM), provide the Amazon Resource Name (ARN) of the ACM certificate. CloudFront only supports ACM certificates in the US East (N. Virginia) Region (us-east-1).

If you specify an ACM certificate ARN, you must also specify values for MinimumProtocolVersion and SSLSupportMethod.

Public Property Certificate System.String

Gets and sets the property Certificate.

This field is deprecated. Use one of the following fields instead:

  • ACMCertificateArn

  • IAMCertificateId

  • CloudFrontDefaultCertificate

Public Property CertificateSource Amazon.CloudFront.CertificateSource

Gets and sets the property CertificateSource.

This field is deprecated. Use one of the following fields instead:

  • ACMCertificateArn

  • IAMCertificateId

  • CloudFrontDefaultCertificate

Public Property CloudFrontDefaultCertificate System.Boolean

Gets and sets the property CloudFrontDefaultCertificate.

If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, set this field to true.

If the distribution uses Aliases (alternate domain names or CNAMEs), set this field to false and specify values for the following fields:

  • ACMCertificateArn or IAMCertificateId (specify a value for one, not both)

  • MinimumProtocolVersion

  • SSLSupportMethod

Public Property IAMCertificateId System.String

Gets and sets the property IAMCertificateId.

If the distribution uses Aliases (alternate domain names or CNAMEs) and the SSL/TLS certificate is stored in Identity and Access Management (IAM), provide the ID of the IAM certificate.

If you specify an IAM certificate ID, you must also specify values for MinimumProtocolVersion and SSLSupportMethod.

Public Property MinimumProtocolVersion Amazon.CloudFront.MinimumProtocolVersion

Gets and sets the property MinimumProtocolVersion.

If the distribution uses Aliases (alternate domain names or CNAMEs), specify the security policy that you want CloudFront to use for HTTPS connections with viewers. The security policy determines two settings:

  • The minimum SSL/TLS protocol that CloudFront can use to communicate with viewers.

  • The ciphers that CloudFront can use to encrypt the content that it returns to viewers.

For more information, see Security Policy and Supported Protocols and Ciphers Between Viewers and CloudFront in the Amazon CloudFront Developer Guide.

On the CloudFront console, this setting is called Security Policy.

When you're using SNI only (you set SSLSupportMethod to sni-only), you must specify TLSv1 or higher.

If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net (you set CloudFrontDefaultCertificate to true), CloudFront automatically sets the security policy to TLSv1 regardless of the value that you set here.

Public Property SSLSupportMethod Amazon.CloudFront.SSLSupportMethod

Gets and sets the property SSLSupportMethod.

If the distribution uses Aliases (alternate domain names or CNAMEs), specify which viewers the distribution accepts HTTPS connections from.

  • sni-only – The distribution accepts HTTPS connections from only viewers that support server name indication (SNI). This is recommended. Most browsers and clients support SNI.

  • vip – The distribution accepts HTTPS connections from all viewers including those that don't support SNI. This is not recommended, and results in additional monthly charges from CloudFront.

  • static-ip - Do not specify this value unless your distribution has been enabled for this feature by the CloudFront team. If you have a use case that requires static IP addresses for a distribution, contact CloudFront through the Amazon Web Services Support Center.

If the distribution uses the CloudFront domain name such as d111111abcdef8.cloudfront.net, don't set a value for this field.
