    Note: Signing data enables the recipient to verify that no modifications
occurred after the data
    were signed. Accepting data with no, wrong or unknown signature can lead to
a corrupted system
    and in extreme cases even to a system compromise.

the keys name. If you
    are not sure whether the presented key is authentic, ask the repository
provider or check his
    web site. Many provider maintain a web page showing the fingerprints of the
GPG keys they are
    using.
