+# What is DKIM
+Docs: https://docs.aws.amazon.com/ses/latest/dg/send-email-authentication-dkim.html
+DomainKeys Identified Mail (DKIM) is an email security standard designed to make sure that an email that claims to have come from a specific domain was indeed authorized by the owner of that domain. It uses public-key cryptography to sign an email with a private key. Recipient servers can then use a public key published to a domain's DNS to verify that parts of the email have not been modified during the transit.
+
+
+This terraform is configuring an Easy DKIM: SES generates a public-private key pair and automatically adds a DKIM signature to every message that you send from that identity, see Easy DKIM in Amazon SES.
+
+The CNAMEs records outcomes of this terraform can be set up in DNS Managment like cloudflare, namecheap, so on.
