Creates a new SecurityContext.
By default, the created SecurityContext contains no keys or certificates. These can be added by calling the methods of this class.
If withTrustedRoots is passed as true, the SecurityContext will be
seeded by the trusted root certificates provided as explained below. To
obtain a SecurityContext containing trusted root certificates,
SecurityContext.defaultContext is usually sufficient, and should
be used instead. However, if the SecurityContext containing the trusted
root certificates must be modified per-connection, then withTrustedRoots
should be used.
