Does anyone know where I can find a completely offline tool that does what this site does?
The source for this seems like a bit of overkill. I'd like to be able to use a cli based tool that shows me relevant man sections for the flags I chose for example
Don't forget that if their software is changing the certificates for every HTTPS site you visit they're probably doing it on the fly. This means that the private key is on your computer. Assuming they generate a per install private key that won't be a big issue but if it's the same private key for all their installs it could get pretty bad once someone gets the key
Keybase is great for managing my keys, but I haven't found any services that make it easy to natively use them. They've sat unused for the ~2 years I've had a Keybase account.
That said, I have about 25 invitations. Anyone want one?
Edit: Not true. I used my keys once to sign a GitHub release for a novelty project nobody uses.
