	       These options are not bitfields - you may specify one only!

	      o $cainfo
		-$cainfo should be an array of trusted CA files/dirs as described in Certificate Verification.

	      o $untrustedfile
		- If specified, this should be the name of a PEM encoded file holding certificates that can be used to help  verify  the  certifi-
		cate, although no trust is placed in the certificates that come from that file.

RETURN VALUES

	Returns TRUE if the certificate can be used for the intended purpose, FALSE if it cannot, or -1 on error.
