Shadow Word: Porn said. It's just a difference in the way the two hash programs display the value; I use HashMyFiles, which prints the hexadecimal (base-16) values with lowercase letters, while QuickHash prints them in uppercase. It mostly comes down to personal preference; when I type them out myself, I always use uppercase A-F because that's how I learned it, but these days a lot of programmers use lowercase a-f -- probably because it's slightly less work to not have to keep pressing the shift key while typing.

The hashes I posted were cut-and-pasted from the HashMyFiles output.
(If anyone's interested in the technical details: Each "digit" in a hexadecimal number represents a 4-bit binary value, and since 4 binary bits have 16 possible combinations (0000, 0001, 0010, 0011, and so on through 1111), but we only have 10 actual "numbers" in our writing system (0-9), we borrow the letters A-F to represent the remaining six combinations.
