An Encryption Software is an application that works primarily in encrypting and decrypting
of data. Normally, it comes it form of files on hard drives, removable media and email
messages. It carries out an algorithm especially designed to encrypt the data on the
computer in which it will only be accessible if there’s an access to the key. The purpose
on data encryption is to be able to prevent third parties from recovering information
especially it is sensitive information such as credit card information. Encryption is a
basic part of modern computer communication and file protection.
There are affecting factors in selecting an encryption algorithm such as security and
speed. One of the popular methods is Ciphers wherein it is categorized in two type,
public key and symmetric key.
Public key is actually based on algorithm, which basically operates “one way”. It is
a manner of reversing one member of key pair using the other member of the pair.
Another is Symmetric ciphers or also known as secret key ciphers, in which it is used
for encryption as well as decryption. To make the messages encrypted, the key used
must remain covert. Stream ciphers are commonly used to encrypt plaintext a bit or
byte at a time. It is usually used during real-time communications like audio and video
information. Block cipher that has the capacity to encrypt block of bytes of plaintext.
Lastly, users should be aware and should have enough knowledge and understanding
about the importance of using Encryption software.
