-----END PGP PUBLIC KEY BLOCK-----
Simply copy that entire text, save it as key.txt, and open a terminal.
In the terminal, use the cd command to navigate to the directory path where you’ve saved key.txt. Then use the gpg --import command.
(Note that Windows uses \ for directory paths, but Linux/macOS use /)
$ cd /path/to/the/key
$ gpg --import < key.txt
Example output:
gpg: key D05AC74F68976E52: "Cryptopower <release@cryptopower.dev>" imported
gpg: Total number processed: 1
gpg: unchanged: 1
You can then delete key.txt.
Once you have the required PGP keys, you can verify the release with:
gpg --verify cryptopower-v1.0.0-manifest.txt.asc
You should see the following if the verification was successful:
gpg: assuming signed data in 'cryptopower-v1.0.0-manifest.txt'
gpg: Signature made Thu 03 Aug 2023 17:08:06 WAT
gpg: using RSA key 5C26BFEC6C2466A528D5551CD05AC74F68976E52
gpg: issuer "release@cryptopower.dev"
gpg: Good signature from "Cryptopower <release@cryptopower.dev>" [ultimate]
That will verify the signature of the manifest file, which ensures integrity and authenticity of the archive you've downloaded locally containing the binaries. Next, depending on your operating system, you should then re-compute the sha256 hash of the archive with sha256sum <filename>, compare it with the corresponding one in the manifest file, and ensure they match exactly.
