=item B<SslPassPhrase>: <passphrase>

Applies to B<execute> and B<get-url>.

B<SslPassPhrase> is optional when B<SslUseCertificate> is enabled.
Its value, if specified, is used to decrypt the contents of the
client's private key file (see B<SslPrivateKeyFile>).  If a passphrase
is required to load the private key and this control has not been
set, the user will be prompted for one.  Naturally, this will cause
problems for automated tasks, so keep that in mind.
