Hi Johannes, |

|
21 |
as far as the above suggestion made by Terje is concerned You're right. |
22 |
Distributed checks could easily lead to "confusion", especially working |
23 |
with mirrors. But MD5 alone IS a joke when it comes to _security_ |
24 |
(here: proof of origin/unmodified developer version). It's quite good |
25 |
to check file corruption during data transfer. But that's it in my |
26 |
eyes. If one wants secure "origin" checks there's the need for gpg |
27 |
signing or something alike. Just using md5 someone who got write access |
28 |
to a portage-server could easily regenerate the sum and paste it into |
29 |
the ebuild including a modified SRC-URL. |

OK. "Even" the OpenBSD devel core team didn't manage to integrate |
32 |
private keys that way (maybe in general they're chaotic). One big |
33 |
problem handling this would be/is/was the key availability for people |
34 |
downloading files ... at least it's like that dealing with some of the |
35 |
OBSD dev-staff ... |
