By disabling VERIFYPEER you switch off the verification of the server's
certificate and by using VERIFYHOST you only verify that the name field
(common name or subjectaltname) matches the host name of the server.
Thus, a man in the middle attack that would use a new (bad) certificate with
the correct name field would not be discovered.
