<!---
	Get the key that we are going to use to encrypt the time
	stamp. Rand() gives us a multidigit number between zero
	and one.
--->
<cfset REQUEST.SpamKey = ToString( Rand() ) />
 
<!---
	Once we get this number, we are going to strip out the
	leading zero/one and decimal place. This should leave
	us with a digit-only string of characters.
--->
<cfset REQUEST.SpamKey = REQUEST.SpamKey.ReplaceFirst(
	"(\d*\.)?0*",
	""
	) />
 
<!---
	Get the time span for which this form is active.
	CreateTimeSpan() gives us a float value to represent the
	7 minutes during which time this form can be submitted.
--->
<cfset REQUEST.ActiveTimeSpan = CreateTimeSpan(
	0,
	0,
	7, <!--- 7 Minutes. --->
	0
	) />
 
<!---
	Get the time spam for which this form MUST be active. This
	form is not allowed to be submitted before it has been live
	for 10 seconds. CreateTimeSpan() gives us a float value
	representation of the time span.
--->
<cfset REQUEST.RequiredActiveTimeSpan = CreateTimeSpan(
	0,
	0,
	0,
	10 <!--- 10 Seconds. --->
	) />
 
<!---
	Get the cut off date for this active form. To get this
	value, we will add the time span above (7 minutes) to the
	current time. NOTE: Since the time span created above is
	a float value, this addition will AUTOMATICALLY convert
	the result to a float rather than a string-style date.
--->
<cfset REQUEST.CutOffDate = (
	REQUEST.Environment.DateTime.Now +
	REQUEST.ActiveTimeSpan
	) />
 
<!---
	Get the early cut off date for this active form (this is
	the time the form is required to exist). Like the above
	date, the results of this will be a float value, not a
	standard string-style date.
--->
<cfset REQUEST.RequiredCutOffDate = (
	REQUEST.Environment.DateTime.Now +
	REQUEST.RequiredActiveTimeSpan
	) />
 
<!---
	Encrpt the cut off date using our randomly generated
	spam key above. Using the CFMX_COMPAT algorithm, we are
	going to convert this to a HEX value.
--->
<cfset REQUEST.CutOffDateEncrypted = Encrypt(
	REQUEST.CutOffDate,
	REQUEST.SpamKey,
	"CFMX_COMPAT",
	"HEX"
	) />
 
<!---
	Encrpt the required cut off date using our randomly
	generated spam key above. Again, we are creating a
	HEX value for this encryption.
--->
<cfset REQUEST.RequiredCutOffDateEncrypted = Encrypt(
	REQUEST.RequiredCutOffDate,
	REQUEST.SpamKey,
	"CFMX_COMPAT",
	"HEX"
	) />
 
<!---
	Encrupt the spam key that we generated above. Seeing
	as our spam key is totally random, once we encrypt it
	with our global encryption key (nutz_4_butts), I don't
	see how it can be cracked.
--->
<cfset REQUEST.SpamKeyEncrypted = Encrypt(
	REQUEST.SpamKey,
	"nutz_4_butts",
	"CFMX_COMPAT",
	"HEX"
	) />
