Setting up DKIM in AWS Route53

Setting up DKIM in AWS Route53

Hi, 

AWS is not allowing me to enter the large DKIM value, which ZOHO needs me to setup for DKIM:
v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCIr6rqDssUHEehaprZvNqlwBR8kGkQn4+ivpkGWSe+2qxyIBz5OE/AKUgDJLq+IoNYHiLn2hFK+RBbEWIr/5iFdurwclFID7z/QiuKxwIZcmCRq5lFf3xiWIqXwyIRTTr390LMDZdwIgJSISuogtNN/Q5Iv9gkJir/fb3OJxlgEwIDAQAB

Can you please provide a solution?

Regards,
