You would need to download the corresponding pubkeys to actually verify these signatures. The signature only contains the key ID of the signer. If we import it from a keyserver we also get the signatures: (rms_id <- gpg_list_keys("rms")$id) "2C6464AF2A8E4C02" gpg_recv(rms_id) Searching: found imported secrets signatures revokedġ 0 0 205 0 gpg_list_signatures(rms_id) id timestamp name email successġ 2C6464AF2A8E4C02 18:32:38 Richard Stallman TRUE However this file does not contain any signatures for this key.

gpg_restart(home = tempdir()) gpg (GnuPG) 2.3.3Ĭopyright (C) 2021 Free Software Foundation, Inc. For this example we store keys in a temporary directory. Use gpg_restart to switch to another home directory, e.g. for a client which uses its own configuration and keyrings. $ gpgme :Class 'numeric_version' hidden list of 1 $ version:Class 'numeric_version' hidden list of 1 GPG defaults to your system keyring, which is the same as the gpg command line utility and system package manager use. Your home directory contains your configuration and the keyrings. It is important to know which version of GPG you are running and where your home dir is. For this reason it is also valid to share GPG public keys via e.g. a website or email.

One should only trust GPG keys on basis of GPG signatures, regardless of how they were obtained. This package automatically retrieves keys and signatures via the gpg_recv function. These servers mirror each other so most keys are available on either one. GPG is compatible with existing PGP key servers. The easiest way to exchange public keys and key signatures is via a keyserver. For new peers, the GPG software helps you figure out which of your current peers has verified the identity of the new peer, perhaps indirectly via a third or fourth peer, and so on: a “web of trust”.

The GPG user determines which peers they choose to trust in their personal keyring. In GPG, anyone can sign another persons key. GPG uses a different system which does not distinguish between peers and authorities. This CA is typically a commercial vendor which verifies your identity (e.g. via a copy of your passport) and then uses their own keypair to sign a certificate containing your public key and your personal name / email / domain. Anyone can create a keypair for any domain/personal name, however we only trust public keys which have been signed by an official CA. HTTPS is based on a system with Certificate Authorities (CA). The major difference between GPG and PKI systems (such as HTTPS) is how we authenticate public keys. If we can not trust our communication channel to be safe, we can only be sure that a public key belongs to given person if it has been signed by someone that we do trust. The complexity in public key systems derives from authenticating public keys.
