From the above code ecx stores the address of the end of the buffer (loc_40107C + 0x79). eax points to the beginning and then in is checked if eateax has reached the end of the buffer by comparing eax with ecx.

As for the buffer at 40107C0x40107C it probably shouldn't be empty as the values are modified in the loop. The code that you pasted should be treadedtreated as data so it should be viewed as 0xF1, 0x06, 0x81, 0x1e, 0xf0, 0xc4, 0x99, 0x1f..0xF1, 0x06, 0x81, 0x1e, 0xf0, 0xc4, 0x99, 0x1f....

Now, there's something under [ebp+buf] that when used on this buffer and adding 0x22 gives some meaningful code.
