Identical by content digest#

This page is generated from the code and must not be edited by hand.

Files whose whole contents give the same fingerprint are grouped as holding the same bytes.

identical_by_content_digest version 2

  • Kind of rule: Which files go together (groups). Says which things count as the same in some respect, and so forms groups.

  • What it concludes: identical

  • Reasoning: entailed. A conclusion cannot be wrong if what it read is right.

  • What it reads: files, which it sorts into groups

Is it available in this version?#

Yes. The engine runs it.

What would defeat it#

Nothing. An entailed conclusion cannot be wrong if what it read is right.

Which digest settles it: the whole-file digest a dive computes wherever two files’ samples agree. Recorded on the conclusion rather than assumed, so that a pool hashed under one algorithm and compared under another is a detectable state rather than a silent mismatch.
