My guess:
It's most likely that "raw binary dump" actually meant a hexdump – a listing that shows each byte in the file as hexadecimal numbers, instead of (or in addition to) the byte itself.
It usually looks like this:
... 00000a0: 6d65 3233 3a6d 6564 6961 7769 6b69 2d31 me23:mediawiki-1 00000b0: 2e31 352e 312e 7461 722e 677a 3132 3a70 .15.1.tar.gz12:p 00000c0: 6965 6365 206c 656e 6774 6869 3332 3736 iece lengthi3276 00000d0: 3865 363a 7069 6563 6573 3636 3230 3ae9 8e6:pieces6620:. 00000e0: b08a 7ef8 00f8 d8b4 a53e 15e3 6bd6 e2c4 ..~......>..k... 00000f0: a7e4 1aa6 c67f 7106 cd3e 1672 decc b5c7 ......q..>.r.... 0000100: 455c a86d 4751 379a f59f 3665 1e8c 128a E\.mGQ7...6e.... 0000110: dec4 e670 ca0f e960 353b 48fe 3dfb c455 ...p...`5;H.=..U 0000120: f940 e102 13d6 8385 1655 4642 3e83 060b .@.......UFB>... 0000130: 585f d353 2ef2 07ff d9e3 aeb6 7329 2192 X_.S........s)!. 0000140: e0a9 7d75 390f 3c16 def6 d806 469e af64 ..}u9.<.....F..d ...
In which each line has a start position, 16 bytes in hex, and the same 16 bytes in "safe" form (that is, bytes between 0x20 and 0x7f shown directly, the rest replaced with .
's).
On Linux, xxd
, hd
, hexdump -C
, or various incantations of od
can be used. On Windows, a number of binary editors like hiew
or HxD.
