What this does provide, despite the vulnerability I noted in the other email, is a good framework for handling the signatures. To defeat the attack I mentioned before, the signatures need to cover: 1. git cat-file commit $commitid |egrep -v '^(tree|parent|commiter)' 2. git diff-tree --no-commit-id -r --raw $commitid 2.1. Grab all of the blobid's from the 4th column. 3. "git show $blobid" for each blobid from #2.1 -- Robin Hugh Johnson Gentoo Linux: Developer, Trustee & Infrastructure Lead E-Mail : robbat2@g.o GnuPG FP : 11AC BA4F 4778 E3F6 E4ED F38E B27B 944E 3488 4E85
