Use this tool to lookup and verify a DKIM TXT record and determine its public key length. You can read more about why I wrote this tool. Please let me know if you find a record that doesn’t parse properly and I’ll update my code.

Hello! Please, add support for .services domain.
Hi, thanks for the tool. Just found out that many similar tools out there are unable to handle long keys…yours works perfectly.
Great tool. If you could please add support for some of the newer TLDs, .properties in particular, that would be swell.
Very handy tool, thank you!
Thanks for the tool! Just a remark:
Base64 encoded data usually wrap lines after 64 chars. The public key your tool did reconstruct wrapped after 78.
Updated to wrap at 64 chars. Thanks for the feedback!
Thank you so much, this is making my life a lot easier.
Thank you VERY much for this tool and moreso for all your knowledge on this topic.
Cyrilick domain or punycode domains not support 🙁
@Evil_Wolf: Can you share a couple example domains and selectors to test so I can work on adding support? Thanks!
Great tool. Just entered a record DKIM record with more than 255 chars and lookup result looked rather funny. I was expecting BIND to concatenate the multiple parts into one! Checked here with success. Then find out that it is the application using this record which is suppose to concatenate the parts.
Hmmm, worked that time, after I updated my DNS to remove the domain. I just put it back, we’ll see how your tool does tomorrow.
Hi Sir,
I have a issue. How to check DKIM Cname record ?
Hi Dave
Thank you so much for providing this tool. I was able to check my Key Strength which was 1024 and upgraded it to 2018 at Google Apps.
This has helped me a lot to implement DMARC and see how Spammers are trying to use my domains for their hideous activities.

Varun
Thanks a lot., real bug killer..!!!
I downloaded a app & payed for it to but I can’t get it to work
This is extremely useful. Thanks for sharing it!
I didn’t want to install the bind-utils just to get the dig utility.
This is great, thanks again.

2048 key length not working?
It should be working, what selector/domain are you testing?
Mine has a 2048 bit key, for an example:
selector: google
domain: protodave.com
Ho do you get the key length ?
Thanks a lot! Very useful tool. 🙂
