A more elegant, controlled way (though it would involve more work) would be to use the gpgme library to verify the signature. Out of the similar posts I have seen none of the solutions fixed whatever is wrong. Hence, we need to grab the public key from a key server (such as pgpkeys.mit.edu) or download it from the author’s web site. Please be sure to check the README of asdf-nodejs in case you did not yet bootstrap trust. The problem with these hashes, though, is that if a hacker replaces files on a website, he can easily replace the hashes, too. c) In case the key hasn’t already been imported (error: ‘gpg: Can’t check signature: No public key’): import the developer’s public key (GPG will try to connect to the Internet using port TCP/11371): Well, have you looked at `/home/sdrafahl/.emacs.d/elpa/gnupg/pubring.gpg`?

Before you can do that you need to tell gpg about our public key… I have a machine at home that works but this one specifically has a problem. We’ll occasionally send you account related emails. I disagree with a proposal to use something like for Emacs key sequences. to your account. To verify your belief that someone has signed a file, you will need a copy of that person's Public Key, a copy of the file, and a copy of the signature-file that was allegedly created through the interaction of the person's Secret Key and the file. I tried the command suggested by @dennismayr which results in: gpg --homedir ~/.emacs.d/elpa/gnupg --keyserver hkp://keys.gnupg.net --recv-keys 066DAFCB81E42C40 Have a question about this project?

The signing and verification process uses public-key cryptography and it is next to impossible to forge a PGP signature without first gaining access to the developer's private key. When doing the public key exchange, the number of prime bits should be high enough to ensure that the channel can’t be eavesdropped on by third parties.
