github.com/adamdecaf/pwnedkeys (go): Package pwnedkeys looks up Certificates, Certificate requests, Keys, etc in the pwnedkeys.com database.  Lookup is done using the SubjectPublicKeyInfo (SPKI) associated with a key. The SPKI fingerprint of a key (or certificate) is the all-lowercase hex-encoded SHA-256 hash of the DER-encoded form of the subjectPublicKeyInfo ASN.1 structure representing a given public key.
