Cool! I usually use gpg-zip for this purpose on machines where I have gpg installed.

  gpg-zip --symmetric --gpg-args --cipher-algo=AES256 --output backup.tar.gpg file1 file2 file3

What HMAC is used to verify the contents of the archive before decryption takes place?

Not a very creative name. There is enough IT related products with the name Arc already.

Not only that, there's a historical program called Arc that is also a file archiver/compressor. It led to PKZIP.

The MAC (not HMAC) used [0] is Poly1305 [1].

What do you do to keep your GPG keys safe (i.e. so you don't accidentally lose them)?

Just a couple of commits from one contributor. I'll keep an eye on it; hope it gets more traction.

in that example he is using symmetric encryption , so a password, no private key.

I'm starting to see this way too often. No one cares.

Clearly at least one person cares, or he wouldn't have commented about it. Not that the comment was useful. But neither was yours.

What does that make yours, then?

It's not clear from the README ... is this a client/server app, wherein I need to have 'arc' living on the server side ?

Or can I just point arc to SSH/SFTP and the server can be "dumb" ?

Mine was useless too, was it not obvious?
