Key Vaults
Kvs should be 16.0 KB in total and should look like this
Kv prices are
Unshared around $85
Shared around $30
Type 2 and type 1 kvs are not to much different you can change the type in kv modder.
A good kv will say something along the lines of kv_dec.bin if it says anything else like kv_dec.bin.bat it is fake and will probably get you keylogged.
