How Does A File Encryptor Work?

An encryptor software program plays a very important role when it comes to protecting information online or offline. In this Internet age, where almost everything is now connected to computers and World Wide Web, there has been a growing need for a program that can provide optimum protection to the electronic data. File encryption is a process where a third-party or a first-party software solution is used to encrypt an entire file. When a file is encrypted, the data is actually rearranged randomly but on the basis of a specific yet highly complicated algorithm. The idea is to prevent others from misusing the data, as a file encryptor makes it completely unreadable by others. It can be used only after decryption, which is another process, where the encrypted information is rearranged in its original format.

The Level Of Protection

The level of protection that an encryptor software program can ensure depends on the length of the algorithm used. The lengthier it is, the complicated the encrypting decrypting processes become. It will be extremely difficult and almost impossible for a third party that is not authorized to use the encrypted information to decrypt the same without the use of the algorithm used in the process of offline or online encryption. The complexity of the algorithm is determined on the basis of its bit size. The bigger its bit size, the more protection it can provide for the data in question. Some common sizes include 256-bit, 128-bit, 64-bit, and 32-bit.

Data Encryption By Servers

When an encryptor program uses the server to encrypt information on other computers that are attached to it, it is commonly referred to as client-side encryption. This process is crucial to ensuring protection of information while it is on its way between the workstations and the server. Sometimes files are hacked even before they reach the server - it usually happens during online data transfer. The encryption online makes the file unreadable. So even if unauthorized people hack it, they will not be able to misuse the same. Whether the file remains encrypted or it is decrypted automatically once it reaches its actual destination, it depends on the settings on the server. You can set the options based on your specific needs and requirements.

Client-Side Encryption Versus Whole File Encryption
The techniques used by an encryptor might be similar in both processes. It is just that both these options are available. It is up to you to decide which one of these two processes you have to use. In general, the only difference between them is that where the client-side encrypting process is used to ensuring safety in data transfer, the whole file data encryptor is used as a general security measure.

You must have the original algorithm that was used to encrypt files to decrypt the same. No matter which online decrypt programs you use, there is no way to perform decryption without the original algorithm. Some encryptor programs are capable to decrypt the files automatically, but many of them will assign a specific key to you when you encrypt a file and then the program will ask you to enter that key to decrypt the file back to its original format.
