How this service works
DKIM public key for selector "hs1" of a domain: looks up hs1._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 hs1 selector will verify. $0.01 per lookup.
Output
Returns parsed details from the hs1._domainkey.<domain> TXT record including: DKIM version (v=), key type (k=, e.g. rsa or ed25519), public key length in bits, whether the domain is in testing mode, and whether the key is revoked (empty p= field). Confirms whether mail signed with the hs1 selector will pass DKIM verification.
Example use cases
Pre-send DKIM validation for email campaign
“Before I send out this marketing email blast, check that our DKIM hs1 selector record on acmecorp.com is valid, not revoked, and not still in testing mode.”
Debugging DKIM signature failures
“Our transactional emails from mailservice.io are failing DKIM checks — can you look up the hs1 selector DKIM record on mailservice.io and tell me what the key looks like and whether anything is wrong with it?”
Security audit of DKIM key strength
“I'm auditing our email security — pull the DKIM hs1 selector record for startupbrand.co and tell me the key type and length so I can check if it meets our 2048-bit RSA policy.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/dkim/hs1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to inspect the DKIM configuration for the 'hs1' selector on a domain — particularly for email deliverability audits, debugging DKIM signing failures, checking key strength, or verifying a key has not been revoked. It is selector-specific and more precise than a generic DNS TXT lookup, as it parses all DKIM record fields automatically.
Side effects
- Domain does not have an hs1._domainkey TXT record — returns not found or empty result
- DNS resolution failure via Cloudflare DoH — network or upstream error
- Malformed TXT record that cannot be parsed — partial or error response
- Revoked key detected (empty p=) — returned as data, not an error
- Domain name input is invalid or malformed — returns validation error
