@michaeljguarino This solution also doesn't work. We still compare two different encryption keys. The SHA is generated from ~/.plural/key When we import some repo from another user the key is always different than ours. The validation was added to check if the current encryption key is different from the one that was used during repo init. The sharing scenario will always fail in this case. In my opinion, we should add a user email address to the .keyid file and validate the key when the emails are equal

Also plural init can't decrypt the repo

[michaeljguarino]

This should extract the key from the crypto provider, in the case of sharing that will be the key decrypted from w/in .plural-crypt. Have you tested it to confirm it doesn't work? If not we probably just need to tweak some of the validation
