### Verifying signatures

Once you've downloaded a Gradle JAR file or a distribution and its corresponding signature file (with a `.asc` extension), you can verify its authenticity against the public key.

For example, to verify the signature of `plugin-publish-plugin-2.0.0.jar` and its signature file `plugin-publish-plugin-2.0.0.jar.asc`, use this command:

```bash

            StringBuilder signature = new StringBuilder();
            signature.append("(");
            for (int i = 0; i < methodDoc.getMetaData().getParameters().size(); i++) {
                if (i > 0) {
                    signature.append(", ");
                }
                signature.append(methodDoc.getMetaData().getParameters().get(i).getName());
            }
