released the new BIsign tools on the BI forums
At the same time Soner
released his GUI for helping you signing add-ons.
Quote Dwarden :
DSUtils 2 contains all tools needed for signing Arma 2: Operation Arrowhead content.
The server with verifySignature 1 will check both v1 and v2 signatures.
With verifySignature 2 the server will reject v1 signatures.
Level checkFile and regularCheck are what admins must use for optimal security.
Remember if you use the signature tool it overwrite the same filename used for v1 with v2.
