SHA256 replaces MD5 in OpenBSD snapshots
A note for OpenBSD snapshot trackers
Since a few days ago the OpenBSD snapshots use sha256 for checksumming instead of md5. Code:

I just read about this, marc.info has been done for a few days.. so I had some catching up to do.
In the long run, SHA256 hashes are much better.. not that I think MD5 is totally useless. |

In context, the move to SHA256 from SHA-1 (128) is probably intended to decrease the likelihood of a hash collision, readers may find the following link of interest on approved crypto strengths and crypto-material-at-key-strength retention periods.
http://www.cse-cst.gc.ca/documents/publications/itsa-asti/itsa11d-eng.pdf Accordingly, SHA-1, as a crypto component, is disallowed as of 2008/12 by the above Canadian govt standards. It's interesting to see what algorithms and key-strengths are deprecating in 2010. /S

Just an added bonus, the new SHA256 hash file contains the xenocara sets now.
