Chronoforms v6 can I encrypt a field and have the email send the encrypted field to email. Essentially I need a form field that a customer can enter an email address in which is then encrypted to md5 standard. This is then sent in an email and saved into the database.
​
Any help would be appreciated.

Sorry Max,
​
I need a specific problem to be solved. I need to encrypt the email address field with opensll_encrpyt so that I can decrypt it at a later date. I am trying to keep the email address field from being revealed when the form is submitted to the server.
​
I have this php code that works to encrypt the text I pass to it. I can decrypt this later. What I would like to to be able to change the field when the form is submitted and the encrypted info saved.
​
$iv = '12345678';

$key256 = '1234567890123456ABCDEFGHIJKLMNOP';
$key128 = '1234567890123456';

printf("iv: %s\n",bin2hex($iv));
printf("key256: %s\n",bin2hex($key256));
printf("key128: %s\n",bin2hex($key128));

$cleartext = 'tim@smdcomputers.com';
printf("clearText: %s\n\n",$cleartext);

// Do 256-bit blowfish encryption:
// The strengh of the encryption is determined by the length of the key
// passed to mcrypt_generic_init
$cipherText = openssl_encrypt($cleartext, 'BF-ECB',$key256,OPENSSL_RAW_DATA,$iv );

Can I do this?

simplified it a bit.
The third line is ment to changed the "extra_email" field to the encrypted field.
Please say this makes sense.

$iv = '12345678';
$key256 = '1234567890123456ABCDEFGHIJKLMNOP';
$this->data("extra_email",0") = openssl_encrypt($this->data("extra_email",0), 'BF-ECB',$key256,OPENSSL_RAW_DATA,$iv );
