Read 1 file, get decryption key, open another file and decrypt it with the key.

Literally what the tile says.

How does one Open one file with quickbms, read values in it and then open another file and use those values as a decryption key?
Without having to manually do it ofc.

It depends by the fields and by the algorithm, let's say:

Code: Select all

getdstring KEY 16
open FDSE "other_file.dat"
encryption xor KEY "" 0 16
get SIZE asize
log "output.dat" 0 SIZE

Your file is probably different but the idea is the same.
