-- | 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:
--
-- -   Which viewers the distribution accepts HTTPS connections from: only
--     viewers that support
--     <https://en.wikipedia.org/wiki/Server_Name_Indication server name indication (SNI)>
--     (recommended), or all viewers including those that don\'t support
--     SNI.
--
--     -   To accept HTTPS connections from only viewers that support SNI,
--         set @SSLSupportMethod@ to @sni-only@. This is recommended. Most
--         browsers and clients support SNI.
--
--     -   To accept HTTPS connections from all viewers, including those
--         that don\'t support SNI, set @SSLSupportMethod@ to @vip@. This
--         is not recommended, and results in additional monthly charges
--         from CloudFront.
--
-- -   The minimum SSL\/TLS protocol version that the distribution can use
--     to communicate with viewers. To specify a minimum version, choose a
--     value for @MinimumProtocolVersion@. For more information, see
--     <https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/distribution-web-values-specify.html#DownloadDistValues-security-policy Security Policy>
--     in the /Amazon CloudFront Developer Guide/.
--
-- -   The location of the SSL\/TLS certificate,
--     <https://docs.aws.amazon.com/acm/latest/userguide/acm-overview.html Certificate Manager (ACM)>
--     (recommended) or
--     <https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_server-certs.html Identity and Access Management (IAM)>.
--     You specify the location by setting a value in one of the following
--     fields (not both):
--
--     -   @ACMCertificateArn@
--
--     -   @IAMCertificateId@
--
-- 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
-- <https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/using-https.html Using HTTPS with CloudFront>
-- and
-- <https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/using-https-alternate-domain-names.html Using Alternate Domain Names and HTTPS>
