Verify a Credential
Confirm that a certificate or report was officially issued by IQ Career Lab. Credential IDs begin with IQCL- (IQ certificate), PCRT- (personality certificate), or ACAD- (Academic report) and appear on the credential and its QR code.
Or upload the signed PDF
Upload a credential PDF to check its embedded cryptographic signature. The file is checked in your session and never stored.
Verify a PDF yourself
Every IQ Career Lab credential PDF is signed with the Ed25519 public key below. You can check a downloaded PDF against it without trusting this page.
- Every IQ Career Lab credential PDF is signed with an Ed25519 key.
- The signature is appended after the PDF's final %%EOF as a line beginning with %%IQCL-SIGNATURE: — it is ignored by PDF viewers but recoverable for verification.
- Version 2 signatures cover the PDF bytes plus the canonical newline, signature marker, version, and certificate ID prefix, so the credential ID cannot be changed independently.
- Or simply upload the PDF on this page — we check the signature for you.
