pflupg-tool : unpack Philips SmartTV firmware

Posted on Fri 16 May 2014 in Tool

pflupg-tool is an unpacking tool for Philips SmartTV firmware (Fusion platform). If your firmware is encrypted, you have to provide the corresponding public key (public exponent + modulus).

You can add public keys in pflupg.h file:

#define PUBLIC_KEYS_CNT 2
// { name, public exponent e (hex string), modulus n (hex string)}
static const char *public_keys[PUBLIC_KEYS_CNT][3] = {
 {"my_key_1", "010001", "AABBCCDD"},
 {"my_key_2", "010001", "010E020F"}
};

Usage: ./pflupg <upg_filename> [key_name]
2 keys available :
* my_key_1
* my_key_2

Source code can be found on GitHub. You'll need Libgcrypt library to compile it.
