HPS VERIFY
Check the file in front of you.
Upload only the document you received. HPS first checks cryptographic identity and resilient provenance. If the registered owner or issuer enabled a Content Integrity Witness, HPS can also explain registered value changes and, in public-text mode, word-level insertions, deletions and replacements without asking the verifier for the original file.
ONE-FILE VERIFICATION
Upload the document you want to check.
Candidate file bytes and complete candidate text stay in your browser. HPS receives the regular file fingerprint and, where available, selected critical-value witness data. If the registered owner explicitly enabled public-text integrity, the signed registered text is returned to your browser and compared locally.
