# makeivs-ng(1)

generate a dummy IVS dump file with a specific WEP key

## NAME

makeivs - generate a dummy IVS dump file with a specific WEP key

## SYNOPSIS

**makeivs** \<ivs file\> \<104-bit key\>

## DESCRIPTION

**makeivs-ng** is a tool designed to generate an IVS dump file with an inputted WEP key. The aim of is tools is to provide a way to create dumps with a known encryption key for tests.
