I am confused as to how SHA-1 hash is calculated for commit, trees and blobs. As per this article, commit hashes are calculated based on following factors:

1. The source tree of the commit (which unravels to all the subtrees and blobs) 2. The parent commit sha1 3. The author info 4. The committer info (right, those are different!) 5. The commit message

Is the same factors involved for trees and blobs hashes as well?

Thanks
