Hi list!

As far as I have gathered, the SHA-1-sum is used as a identifier for commit=
s,=20
and that is the primary reason for using sha1.  However, several places=20
(including the google tech-talk featuring Linus himself) states that the id=
's=20
are cryptographically secure.

As discussed in [1], SHA-1 is not as secure as it once was (and this was in=
=20
2005), and I'm wondering - are there any plans for migrating to another=20
hash-algorithm? I.e. SHA-2, whirlpool..
