The thing that made the document enforceable is the first casualty of removing the part you were not allowed to keep.
Not "can you redact a document". It is can you redact after signing without the recipient's copy failing verification.
Redaction applied in a way the signature's integrity check accounts for, so what remains still verifies against what was actually signed.
The redaction itself is recorded: what was removed, when, and by whom.
Applies to documents signed through Identity & Signing's routes: eSigning and qualified signatures.
A signature that fails verification after a legitimate redaction looks identical, to the person receiving it, to a tampered document. Explaining the difference after the fact is a worse conversation than not having it.
What can be redacted, and by whom, set per document type.
Redacting after signing without breaking the signature avoids explaining why a legitimate edit looks like tampering.
A record of what was removed and when.
Most signing products treat any post-signature edit as tampering, full stop. This one is built to tell a legitimate redaction from tampering, which is the unusual part.
