A programmer and Founder of Girfa
IT Services, working from 2009.At Starting computer teaching was my full-time job but after 10 years of teaching I chose to programming as a full-time job and teaching become part-time. In real life, I am very lazy and I made it my coding style I always try to make a reusable component that’s my USP for programming which saves my time and extra working both.

RSA Alogorithm
The RSA algorithm is an example of asymmetric cryptography, which is widely used in worldwide for securing sensitive while sending insecure medium like the internet.
RSA was first described in 1977 by Ron Rivest, Adi Shamir and Leonard Adleman of the Massachusetts Institute of Technology. Two types of keys are used, public and private. Private is secrete key used by the owner or receiver. Data can be encrypted using a public or private key, but decryption can be done only with the private key.

Form Validation,File Type Validation : Javascript
It’s a good practice to validate your form using script before sending because it’s giving quick response than server validity. But keep in mind server validation is always necessary because JavaScript may be disabled by the user. So server validation is mandatory. I am presenting complete code for validating a check box, textbox and file. My main focus is on file validating because file validation is complicated task for new web developers So this will help you a lot.

<script language="javascript">
function validate_mar_news(pic,fl,code) //validate add news pic for home page marquee
{
var check_box=document.getElementById(pic);
var file=document.getElementById(fl);
var code=document.getElementById(code);
var flag=true;
if(check_box.value=="Select Page Number")
