Is there a pre-made small image I can copy to a flash drive that is just a base install of a version of linux, and gpg that I can use to offline generate and sign some keys? preferably with an encrypted partition that stores the secret key, and a unencrypted partition that I can store the subkeys on...
@nytpu @epoch I suspect #Tails linux would have GPG pre-installed so you could do that. Tails is a live distro that runs off a USB stick. Also, you can get a list of distros that include GPG here: https://distrowatch.com/search.php?pkg=gnupg&relation=similar&pkgver=&distrorange=InLatest#pkgsearch
@resist1984 @epoch Oh yeah, I'm aware of Tails, but I think the intent here is more for a bootable system exclusively used to manage your keys without doing anything else (nothing else that isn't absolutely necessary is included). Something simple like a buildroot system would make it easier to audit all the software on the system and be relatively assured that it's secure. Not that Tails isn't secure, but I do like the idea of dedicated software that isn't multi-purpose for security purposes.
Plus it'd be a fun excuse for me to learn how to use buildroot
@nytpu @resist1984 You replied pretty much what I was about to reply, but sooner.
@resist1984 @epoch Also it'd be nice to be able to use one of the 1GB and 2GB flash drives I have lying around, and I don't know if any security-focused live distro would fit on those, or at least be able to fit along with two persistent partitions (one encrypted, one unencrypted)
@epoch @nytpu It's a long list, but if you recognize any that are purely live distros that would cover your needs. I noticed Tails and Knoppix are both listed.. although possibly not as small as you're after.
