Example
The following example encrypts and decrypts a text string. It lets you specify the encryption
algorithm and encoding technique. It also has a field for a key seed to use with the
CFMX_COMPAT algorithm. For all other algorithms, it uses the
to generate a secret key.
<h3>Decrypt Example</h3>
<!--- Do the following if the form has been submitted. --->
<cfif IsDefined("Form.myString")>
<cfscript>
/* GenerateSecretKey does not generate keys for the CFMX_COMPAT algorithm,
so we use a key from the form.
*/
if (Form.myAlgorithm EQ "CFMX_COMPAT")
theKey=Form.MyKey;
// For all other encryption techniques, generate a secret key.
else
theKey=generateSecretKey(Form.myAlgorithm);
//Encrypt the string.
encrypted=encrypt(Form.myString, theKey, Form.myAlgorithm,
Form.myEncoding);
//Decrypt it.
decrypted=decrypt(encrypted, theKey, Form.myAlgorithm, Form.myEncoding);
</cfscript>
<!--- Display the values used for encryption and decryption,
and the results. --->
<cfoutput>
<b>The algorithm:</b> #Form.myAlgorithm#<br>
<b>The key:</B> #theKey#<br>

<b>The string:</b> #Form.myString# <br>
