How this service works
DKIM public key for selector "github" of a domain: looks up github._domainkey.<domain> (TXT, Cloudflare DoH) and parses v=, k=, key type, public-key length, testing flag and whether the key is revoked (empty p=). Confirms that mail signed with the github selector will verify. $0.01 per lookup.
Output
Returns parsed fields from the github._domainkey.<domain> TXT record including: version (v=), key type (k=), public key data, key bit length, whether the domain is in testing mode, and whether the key is revoked (empty p= field). Confirms if mail signed with the github selector will successfully verify.
Example use cases
Verify GitHub email signing setup
“Can you look up the DKIM github selector for acmecorp.com and tell me if emails signed with it will pass DKIM verification, and whether the key is revoked or still in testing mode?”
Audit DKIM key strength for security review
“I'm auditing domain security for clientdomain.io — can you check the github._domainkey DKIM record and tell me what key type and bit length they're using?”
Troubleshoot GitHub notification email failures
“GitHub notification emails from notifications@githubmail.com seem to be failing DKIM checks — can you look up the github DKIM selector for githubmail.com and tell me if the record looks valid or if there's something wrong with it?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/github?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to inspect the 'github' DKIM selector for a domain — i.e., github._domainkey.<domain>. It is ideal for verifying GitHub-related email signing configurations, auditing DKIM key strength and revocation status, or troubleshooting delivery failures for GitHub-originated emails. Prefer this over a generic DNS TXT lookup when you need parsed, structured DKIM fields rather than raw TXT data.
Side effects
- Domain has no github._domainkey TXT record — returns NXDOMAIN or empty result
- DKIM record exists but key (p=) is empty — flagged as revoked
- DNS resolution failure via Cloudflare DoH — upstream timeout or error
- Malformed TXT record that cannot be parsed — missing required DKIM tags
- Domain input is invalid or not a resolvable domain
