Modifying Netsuite Object on loading - encryption

Question

I am very new to Netsuite. I am trying to do encryption in Netsuite. It works when I add UserEvent Scripts beforeSubmit. But I wanted to decrypt the encrypted text in beforeLoad function. I am able to read the encrypted text and decrypt it successfully as well. But setting it back in the object fails and I see decrypted text in Netsuite UI. Any directions or help is appreciated.
thanks
// this function works
function beforeSubmit(type) {
var email = nlapiGetFieldValue('email');
var newEmail = 'LifeSpan.' + email;
nlapiSetFieldValue('email', newEmail );
nlapiLogExecution('DEBUG', 'Modified before Submit ' + email + ' to ' + newEmail);
}
// this printed "Modified before Submit customercare#abc.com to LifeSpan.customercare#abc.com"
// this function doesn't work; even though the correct value is printed correctly in the log
function beforeLoad(type, form, request) {
var email = nlapiGetFieldValue('email');
if(email.indexOf('SaaSSpan.') != -1) {
var newEmail = email.substring(9);
nlapiSetFieldValue('email', newEmail );
nlapiLogExecution('DEBUG', 'Modified before load ' + email + ' to ' + newEmail);
}
}
// this printed "Modified before load LifeSpan.customercare#abc.com to customercare#abc.com"...but I am still seeing LifeSpan.customercare#abc.com in the user interface

I will suggest you to try this code in a client script(PageInit and SaveRecord Events).
Works fine for me.
My Code :
function PageInit(type) {
try {
if (type == 'edit') {
var email = nlapiGetFieldValue('email');
if (email != null && email.indexOf('LifeSpan.') != -1) {
var newEmail = email.substring(9);
nlapiSetFieldValue('email', newEmail);
nlapiLogExecution('DEBUG', 'Modified before load ' + email + ' to ' + newEmail);
}
}
}
catch (err) {
nlapiLogExecution('ERROR', 'PageInit', err);
}}
function SaveRecord() {
try {
var email = nlapiGetFieldValue('email');
var newEmail = 'LifeSpan.' + email;
nlapiSetFieldValue('email', newEmail);
nlapiLogExecution('DEBUG', 'Modified before Submit ' + email + ' to ' + newEmail);
}
catch (err) {
nlapiLogExecution('ERROR', 'SaveRecord', err);
}
return true;}
nlapiSetFieldValue can be used in user event beforeLoad scripts to initialize field on new records or non-stored fields.
