Notes and Comments
Das Archiv enthält komprimierte(deflate) und unkomprimierte Daten,
Kopf und Verzeichnis sind einzeln verschlüsselt. Hier der Algorithmus:
(anzahl ist die Größe des Blocks durch 2, also für den Kopf = 130)
English:
The archive contains compressed(deflate) and uncompressed data,
header and dictionary are separately encrypted. Here is the algorithm:
(anzahl is the size of the block divided by 2, for the head = 130)
mov ebx, puffer
mov ecx,0
mov x,0xA2C2A
start:
mov eax,x
imul eax,eax,0x343FD
add eax,0x269EC3
mov x,eax
shr eax,0x10
and eax,0x7FFF
mov ebx, ecx
shl ebx, 1
add ebx, puffer
xor word ptr [ebx], ax
inc ecx
cmp ecx, anzahl
