=item B<DsvVerifySignature>: [Y|N]

Applies to B<execute>.

B<DsvVerifySignature> is optional.  When enabled ('Y' or 'y'), it
instructs the application to verify the signature of the requested
payload.  Signatures are verified against one or more certificates
located in B<DsvCertificateTree>.  The default value is 'N'.

If this control is enabled and the payload's signature is missing or
invalid, B<WebJob> will abort, and the downloaded payload will not be
executed.  This helps to protect the client in the case where the
B<WebJob> server can no longer be trusted (e.g., because it has been
compromised).

Note: Certificate chains and expiration dates are not checked in the
verification process.  It is the responsibility of the B<WebJob>
administrator to periodically manage (i.e., add, remove, update) any
certificates installed on the clients.

Note: Digital Signature Verification (DSV) support is a compile-time
option, which is enabled by default.  However, if DSV support is not
compiled into the binary, WebJob will abort with an error if you try
to use this (or any) DSV control in the config file.  To determine if
DSV support is compiled into the binary, run the following command:

    webjob --version
