To access Terminal, press command-spacebar and type “Terminal”. shasum is run from the Terminal application. OSX allows hash values to be checked with the shasum utility. Think of a hash value as an immutable, unique identifier that can be assigned to any file. We are immediately faced with a dilemma: how do we know that our copy of GPG Suite is authentic? We can’t verify a signature because if we could do that we wouldn’t need GPG Suite.įortunately, we can verify the installer’s hash value. Begin by downloading the installer from the main page. Download and Install GPG SuiteĪ popular PGP implementation on OSX is GPG Suite. Implementations are available for all operating systems. The standard method for signing binaries is known as Pretty Good Privacy (PGP). A forged file that changes a single bit can be detected with this system, as can a developer who attempts to apply an invalid signature. Users verify the download using the developer’s public key. The developer signs a download with a private key. The same idea can be applied to software downloads. Many Bitcoin users are familiar with the idea of digital signatures. The phishing site was followed as the first advertising link from a Google search. For example, in 2017 a Reddit user reported that a phishing site was deploying malware through a forged copy of Electrum, resulting in the loss of five bitcoin. The loss is irreversible and can be life-changing. When the unwitting user enters the private key or seed, the wallet steals the funds.
