Introduction

In this article I will provide you an approach of using RSA algorithm for long String. As you know that RSA algorithm is limited 117 bytes, long strings can not be encrypted or decrypted. However it is possible to break the bytes into several chunks and then to encrypt or decrypt the contents. This algorithm is used for asymmetric cryptography. For asymmetric cryptography, you can click this link.

Technicalities

In this article I provide below the complete example for encryption and decryption of long strings. If you use the method of Cipher class ie.doFinal( byte[] bytesString), it will throw exception that it can be encrypted for more than 117 bytes for RSA.  But in the real application, you may not be sure about the length of the String you want to encrypt or decrypt. In this case you have to break the bytes and then to encrypt it. Please refer to the (more…)

So, you bought a shiny new operating system from Microsoft – Windows 7.

You feel safe with this?

Windows 7 will undoubtedly require serious matters – it has some security features built

The question, however, is that the other results of the operating system that allows you to save yourself from harm’s way?

Here is a list of 22 programs that I have found that seems to play well with Windows 7 –
