Update: format-bytes.py Version 0.0.15

Filed under: My Software,Update — Didier Stevens @ 9:05

This new version of format-bytes.py adds IPv6 representations:

Big-endian (b), little-endian (l) and 4 32-bit little-endian unsigned integers (l4).

And if you use a # to pass on literal data (here in hexadecimal: #h#), then the data is also printed.

Update: pecheck.py Version 0.7.16

Filed under: My Software,Update — Didier Stevens @ 0:00

This new version adds two new values for option -l.

One could already use option -l P to locate all PE files inside an arbitrary binary file.

Option -l PE also adds entries for the extra (E) data, e.g., the data in between found PE files.

Option -l PO is like PE, but adds some more information for the other (O) files: the magic header (hex & ASCII).
