 fingerprint SSH private keys and identify\n   which Git hosting accounts t
 hey unlock. In incident response and red\n   team work\, finding a private
  key is common\, but scoping impact is slow\n   and manual. KeyChecker aut
 omates the two primitives defenders and\n   attackers both use: safe SSH h
 andshakes that can reveal the mapped\n   username\, and read only git ls-r
 emote probes that confirm whether a\n   key can access a target repo.\n\n 
   The tool performs local key intelligence first\, supporting OpenSSH\,\n 
   PEM\, and DER formats\, detecting key type (ed25519\, rsa\, ecdsa\, dsa)
 \,\n   key size\, passphrase protection\, fingerprints (SHA256 and MD5)\, 
 and\n   useful metadata from key comments. It then validates the key acros
 s\n   multiple providers including GitHub\, GitLab\, Bitbucket\, Codeberg\
 ,\n   Gitea\, and Hugging Face\, extracting usernames where possible\, and
 \n   optionally using a GitHub token for organization discovery.\n\n   Key
 Checker also supports repository discovery with a wordlist and\n   configu
 rable concurrency\, giving a clear blast radius report like\n   “this ke
 y unlocks these private repositories.” It is designed for\n   authorized
  assessments\, runs locally\, and avoids write operations.\n\n   SpeakerBi

 esearch and a long time\n   offensive security practitioner with a focus o
 n application\, cloud\,\n   and supply chain security. He has delivered tr
 ainings and talks at\n   Black Hat (USA\, Europe\, Asia)\, Nullcon\, c0c0n
 \, BSides\, Rootconf and\n   multiple other events\, and runs projects suc
 h as Hacking Archives of\n   India to highlight real work from the securit
 y community. His courses\n   are built from real consulting and red team e
 xperience\, with an\n   emphasis on attack chains that actually show up in
  the field and\n   defenses that teams can implement the next day.\n\n   L
