I assume these others cleared it up? The basic idea is that the |
| 27 |
'md5sum' program will compute the sum, and so you can use that to |
| 28 |
verify the authenticity of the binary downloads. The rest of email |
| 29 |
was, as they said, an example of doing so on a small randomly-generated |
| 30 |
file. |

It reads 512 blocks from the input file (if=/dev/urandom) and writes it |
| 33 |
to the output file (of=/tmp/md5src). |
