DKIM signature online test

Created: — modified: — tags: net e-mail

If you ever wanted to see how validity of DKIM signature will be affected by changing email headers and / or message body

There's an easy online tool for that now!

Well, as long as pasting text into a webform is easier for you than into a locally installed opendkim-testmsg CLI tool.

Just navigate to and play with your message. Possible uses include restoring messages mangled by mailing lists into their "original" state.

Let me know if you find any use for it :)
