The md5sum is a value encoded in hexadecimal. Case is insignificant in a hexadecimal value. You can prove this to yourself by trying an experiment. /tmp$ echo a > /tmp/a /tmp$ md5sum /tmp/a > /tmp/a.md5sum /tmp$ cat /tmp/a.md5sum 60b725f10c9c85c70d97880dfe8191b3 /tmp/a /tmp$ md5sum -c /tmp/a.md5sum /tmp/a: OK /tmp$ awk '{print toupper($1), $2}' /tmp/a.md5sum 60B725F10C9C85C70D97880DFE8191B3 /tmp/a /tmp$ awk '{print toupper($1), $2}' /tmp/a.md5sum | md5sum -c - /tmp/a: OK Please ask questions on the address@hidden mailing list rather than in the bug tracker.
