I just read some general discussions on the topic in misc. security related
boards and got the impression that the consensus was that MD5 should be
phased out and replaced by SHA-1. Also have a look at the URL in my reply to
Christian Stockner. It is my impression that SHA-1 can't be easily cracked
using brute-force, which is viable with MD5, and thus MD5 should be replaced
by SHA-1.
I might of course have misunderstood as this is not my field of expertise.
