Question about Key length issue when registering dkim record (Bydesign)

63 Views Last edit Sep 20, 2023 at 05:01 AM 2 rev

Hi All,

Assuming the DKIM properties I've been given are:

  • Selector: byd-busi-my000000
  • Domain: EDF.co.kr
  • Key : v=DKIM1; k=rsa; p=ABC/00876+aadfbb

In DNS where registration of more than 255 characters is not possible, I understand that you can use " to separate it into 2 parts and register it in one line.

(https://aws.amazon.com/en/premiumsupport/knowledge-center/route53-resolve-dkim-text-record-error/)

But I still get an error exceeding 255 characters in DNS and the registration is not possible.

SAP says that an already issued key cannot be reissued with a key less than 255 characters.

I would like to send a purchase order to a vendor to my domain address.

ex) In case of "v=DKIM1; k=rsa; p=ABC/00876+aadfbb"

Attempted to register in one line with "v=DKIM1; k=rsa; p=ABC/00""876+aadfbb".

* The attached photo shows the details of registration in DNS when the initial key of less than 255 characters was received before the key change. (It was a Green registration.)

ex) domain : EDF.co.kr

Regards,
