Options

Help : 
                ./main <target_file> xor : target_file is encrypted (only xor encryption) with a random key 
                ./main <target_file> not : target_file is encrypted (xor and not encryption) with a random key 
                ./main <target_file> xorp : target_file is encrypted (complex encryption) with a random key

@XOR

Encryption :

base_addr[i] ^= random_int;

where base_addr[i] represents each bytes of the .text, and random_int a random int ^^

@NOT

base_addr[i] = ~base_addr[i] ^ random_int;

where base_addr[i] represents each bytes of the .text, and random_int a random int ^^

@XORP

base_addr[i] = ~base_addr[i] ^ random_int;
base_addr[i] ^= x;
x = ~x;

where base_addr[i] represents each bytes of the .text, and random_int a random int ^^
