Not sure if I understood what you are saying. My impression is that you have an existing repo, cloned from a server (with clone on a server;-), and you now want to have the in-repository file blobs be stored in an encrypted manner. It sounds as if you have two problems. 1. your starting point is with the coin upside down. You want your existing repos (local and server) to actually contain encrypted data, and then on checkout they will be filters to be un-encrypted (plain text). - this would explain the sudden appearance of the diff at the point where you start storing encrypted blobs. 2. the smudge/clean filters, at least to me, are described in the manuals in the opposite manner than expected. you may have the same problem, and it may be the cause of the 'wrong way around' perceived diffs (assuming 1. wasn't the problem).
I didn't have time to actually check stuff, but those are the issues I would consider clarifying. -- Philip On Friday, June 9, 2023 at 3:49:18 PM UTC+1 mag...@therning.org wrote: > I'm trying out age[1] as a filter for encrypting files in a git > repo but I must be missing something because every new clone > thinks the encrypted file has changed, and if I commit that change > then every other clone sees a diff after pulling in the change. > > The main reason I want to try out age is that it can make use of > SSH keys for encryption, which makes it a bit nicer than something > like git-crypt. > > I'm setting it up like this: > > --------------------------------------------- > ❯ cat .gitattributes > *.secret filter=age > > ❯ git config -l --local|grep filter.age > filter.age.smudge=age --decrypt -i ~/.ssh/id_ed25519 - > filter.age.clean=age --encrypt -R ~/.ssh/id_ed25519.pub - > --------------------------------------------- > > Here's a sequence setting up a first repo: > > --------------------------------------------- > ❯ git init > Initialized empty Git repository in /home/user/tmp/age-0/.git/ > > ❯ echo '*.secret filter=age' > .gitattributes > > ❯ git config --local --add filter.age.smudge "age --decrypt -i > ~/.ssh/id_ed25519 -" > > ❯ git config --local --add filter.age.clean "age --encrypt -R > ~/.ssh/id_ed25519.pub -" > > ❯ echo "a secret" > foo.secret > > ❯ echo "not a secret" > bar.txt > > ❯ git add .gitattributes bar.txt foo.secret > > ❯ git commit -m 'The first commit' > [main (root-commit) ae75577] The first commit > 3 files changed, 2 insertions(+) > create mode 100644 .gitattributes > create mode 100644 bar.txt > create mode 100644 foo.secret > --------------------------------------------- > > Now I can make a clone: > > --------------------------------------------- > ❯ cd .. > > ❯ git clone age-0 age-1 > Cloning into 'age-1'... > done. > > ❯ cd age-1 > > ❯ git ls-files > .gitattributes > bar.txt > foo.secret > > ❯ cat foo.secret > age-encryption.org/v1 > -> ssh-ed25519 ozAWLA ReSnu8CTgPgnuKUMvG8PWTcc7Lr5IHkKaWc6k4Hfsms > dHsdERPHdsdOQluzyeeRamfjIrmsc2pQ+lhwLlt/0no > --- aHijNp3L2/0MeE/EXWwVhVwyv1uBYW1Ake055jico5M > WF}`YqBO7Ԏwߨ% > --------------------------------------------- > > So far so good.
