The last post for my SLAE certification is about encryption of shellcode. As usual you can find all my files on github<\/a>.<\/p>\n

Nothing special in place.<\/p>\n

    \n
  1. Pick your favourite shellcode<\/li>\n
  2. Use my custom AES encrypter<\/li>\n
  3. Insert the encrypted shellcode and secret AES key into the decrypter<\/li>\n
  4. Test the decrypted shellcode in our skeleton shellcode.c file<\/li>\n
