Fixing TXTRDATATooLong Errors for AWS Route 53

RFC 4408 3.1.3 says

     IN TXT "v=spf1 .... first" "second string..."
   MUST be treated as equivalent to
      IN TXT "v=spf1 .... firstsecond string..."
   SPF or TXT records containing multiple strings are useful in
   constructing records that would exceed the 255-byte maximum length of
   a string within a single TXT or SPF RR record.

so if you are getting error “TXTRDATATooLong” a solution for you will be splitting it into multiple strings within the same record set. For example, instead of:

"v=DKIM1; k=rsa; g=*; s=email; h=sha1; t=s; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDx2zIlneFcE2skbzXjq5GudbHNntCGNN9A2RZGC/trRpTXzT/+oymxCytrEsmrwtvKdbTnkkWOxSEUcwU2cffGeaMxgZpONCu+qf5prxZCTMZcHm9p2CwCgFx3

you can pick a split point where each part is less than 255 characters long and put [double quote][space][double quote] 

for example I tried:

"v=DKIM1; k=rsa; g=*; s=email; h=sha1; t=s; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDx2zIlneFcE2skbzXjq5GudbHNntCGNN9A2RZGC/trRpTXzT/+oymxCytrEsmrwtvKdbTnkkWOxSEUcwU2cffGeaMxgZpONCu+qf5prxZCT" "MZcHm9p2CwCgFx3reSF+ZmoaOvvgVL5TKTzYZK7jRktQxPdTvk3/yj71NQqBGatLQIDAQAB;"

and as a result I’ve got:

dig -t TXT long.xxxxxx.yyyy
long.xxxxxxx.yyyy. 300    IN      TXT     "v=DKIM1\; k=rsa\; g=*\; s=email\; h=sha1\; t=s\; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDx2zIlneFcE2skbzXjq5GudbHNntCGNN9A2RZGC/trRpTXzT/+oymxCytrEsmrwtvKdbTnkkWOxSEUcwU2cffGeaMxgZpONCu+qf5prxZCT" "MZcHm9p2CwCgFx3reSF+ZmoaOvvgVL5TKTzYZK7jRktQxPdTvk3/yj71NQqBGatLQIDAQAB\;"

Note that returned TXT contains [double quote][space][double quote] , however the RFC above mandates that string to be treated as the same as concatenated one.

Note that your example does the same too on 128 character boundary

dig TXT                                                                                                                                      /workspace/stepany-HaasControlAPI-development
