What is a BISIGN file

BISIGN files mostly belong to Arma 3 Tools. BISIGN files are digital signature files used in Bohemia Interactive games such as Arma 3 and DayZ.
They store encoded cryptographic data that confirms the authenticity and integrity of game package files – for example, PBO archives. The game engine or server reads these files to ensure that the associated game content has not been altered.
Usage details:

They serve as the digital signature for Arma 3 packages, validated via Arma 3 Tools.
They are used for DayZ PBO signature verification by Bohemia Interactive (Bohemia Interactive).
They support integrity checks during game server operations and mod development.
