## Verifying the release

In order to verify the release, you'll need to have `gpg` or `gpg2` installed on your system. Once you've obtained a copy (and hopefully verified that as well), you'll first need to import the keys that have signed this release if you haven't done so already:

``` bash

gpg --keyserver hkps://keys.openpgp.org --recv-keys 44F0AAEB77F373747E3D5444885822EED3A26A6D

```

Once you have his PGP key you can verify the release (assuming `manifest-v4.0.0.txt` and `manifest-v4.0.0.txt.sig` are in the current directory) with:

``` bash

gpg --verify manifest-v4.0.0.txt.sig manifest-v4.0.0.txt

```

You should see the following if the verification was successful:

``` bash

gpg: Signature made Fri 13 Sep 2024 08:06:52 AM -03

gpg: using RSA key 44F0AAEB77F373747E3D5444885822EED3A26A6D

gpg: Good signature from "greenart7c3 "

```

That will verify the signature on the main manifest page which ensures integrity and authenticity of the binaries you've downloaded locally. Next, depending on your operating system you should then re-calculate the sha256 sum of the binary, and compare that with the following hashes:

``` bash

cat manifest-v4.0.0.txt

```

One can use the `shasum -a 256 ` tool in order to re-compute the `sha256` hash of the target binary for your operating system. The produced hash should be compared with the hashes listed above and they should match exactly.
