PDFCanon vs. Glasswall: Deterministic PDF Normalization vs. CDR
· 4 min read
Glasswall and PDFCanon both handle PDFs in security-sensitive contexts. They answer different questions.
Glasswall is primarily a Content Disarm and Reconstruction platform. Its job is to neutralize risky file content before it reaches a user or system.
PDFCanon is a deterministic PDF normalization API. Its job is to turn untrusted PDFs into byte-stable canonical documents with stable SHA-256 hashes and machine-readable audit reports.
