[PATCH] Documentation: clarify signature verification

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I encountered some issues with the git documentation while modifying
my deployment scripts to enforce that the tree being fetched was
signed by a trusted key.

It was unclear which commits needed to be signed (in the case of `git
merge`) and what were the criteria for the signature to be considered
valid.

Here is a patch proposal.
