|
|
|
JMX::Jmx4Perl::Agent::Jolokia::Verifier::OpenPGPVerifier - Verifies PGP
|
|
signature with L<Crypt::OpenPGP>
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This verifier uses L<Crypt::OpenPGP> for validating a PGP signature obtained
|
|
from the download site. Ie. each URL used for download should have (and does
|
|
have) and associated signature ending with F<.asc>. This verifier typically
|
|
quite robust, however installing L<Crypt::OpenPGP> is a bit clumsy, so you
|
|
might omit this one.
|
|
|
|
=head1 IMPORTANT
|
|
|
|
It is not used currently since the new agents has been signed with 'digest
|
|
algortihm 10' which is not supported by OpenPGP. Use a native GnuPG instead
|
|
(i.e. a 'gpg' which is in the path)
