  • Update the key length that should be used for Easy DKIM.

  • Change from using no DKIM authentication to using Easy DKIM.

  • Change from using no DKIM authentication to using BYODKIM.

  • Change from using Easy DKIM to using BYODKIM.

  • Change from using BYODKIM to using Easy DKIM.

Syntax

To declare this entity in your Amazon CloudFormation template, use the following syntax:

JSON

{ "DomainSigningPrivateKey" : String, "DomainSigningSelector" : String, "NextSigningKeyLength" : String }

Properties

DomainSigningPrivateKey

[Bring Your Own DKIM] A private key that's used to generate a DKIM signature.

The private key must use 1024 or 2048-bit RSA encryption, and must be encoded using base64 encoding.

Important

Rather than embedding sensitive information directly in your CFN templates, we recommend you use dynamic parameters in the stack template to reference sensitive information that is stored and managed outside of CFN, such as in the Amazon Systems Manager Parameter Store or Amazon Secrets Manager.

For more information, see the Do not embed credentials in your templates best practice.
