Amazon SES now supports 2048-bit DKIM keys
Amazon Simple Email Service (Amazon SES) customers can now use 2048-bit DomainKeys Identified Mail (DKIM) keys to enhance their email security. 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.

Until now, Amazon SES supported a DKIM key length of 1024-bit, which is the current industry standard. With this launch, customers can choose to use either 1024-bit keys or 2048-bit keys regardless of whether they use the Amazon SES Easy DKIM feature or Bring Your Own DKIM. The longer 2048-bit length makes it more challenging to break the DKIM key, thus providing customers enhanced email protection and domain authentication. To learn more about using the 2048-bit DKIM keys, see this page in the Amazon SES Developer Guide.
