You still leak at least length, so not a full destruction

• mjevans 2y ago
  Traditional redaction implies a retention of length unless an entire block is considered protected / classified / secret in some way. To destroy even length, or possibly stenographic content a transcription and maybe rephrasing might be required. However at that point it's better to go for a summary that avoids the content and know for sure that there's loss of meaning.
