- Handle Headers instance in TSA request detection (not just plain objects)
- Wrap timestampPdf with createCorsAwareFetch for OCSP/cert chain requests
- Pass 'success' type to showAlert on successful timestamp
- Add TSA URL context to timestamp error messages with cause
- Remove redundant Uint8Array wrapping in TimestampNode
Add document timestamping to the Secure PDF section using RFC 3161
protocol. Users can select from preset TSA servers (DigiCert, Sectigo,
SSL.com, Entrust, FreeTSA) or enter a custom TSA URL. No personal
certificate is required — only a cryptographic hash is sent to the server.
Key changes:
- Timestamp PDF page with TSA server selector, FAQ and SEO structured data
- timestampPdf() function with CORS proxy URL resolution
- TimestampNode for the workflow engine
- Tool entry in Secure PDF category + homepage i18n
- Built-in CORS proxy middleware for dev/preview
- Translations for all 16 languages
Tested with DigiCert, Sectigo and Entrust TSA servers. Timestamps are
verifiable in Adobe Acrobat (ETSI.RFC3161 SubFilter).
