Encryption is the key process to convert plain text to cipher text so that it can not be read, updated or modified with the another unauthorised user who don’t have the right in the form of decryption keys. This encryption algorithm is useful not only in networking and client-server transmission but also useful in application data transfer.

The encryption algorithm is useful in converting all kind of sensitive information contained in URLs, databases, cookies and variables. All the server and client communication is handled through SSL (secured socket layer) technique to save the sensitive information from unauthorised information.

To perform encryption algorithm, many packet sniffers are used for troubleshooting. Packets travel through the network service path within the group of network. Before reaching its main destination, data actually passes via the network hardware. If any hardware has the packet sniffer, the data is shown to the user.   

The lacuna present in the coldfusion framework is the weak encryption parameters. Before coldfusion version 8, XOR based encryption algorithm was used but in the latest versions, actual MD5 algorithm was used to perform the hashing function. The value of one hash is always 32 bytes.

In the latest versions of coldfusion, PBE (password based encryption)  algorithms for performing encryption is very popular. In this technique, password are used for setting the encryption and decryption keys. The encryption key is also known as the salt value which is of 8byte in length.
