What Is Encryption
Encryption is a method or a technique
used to encode a message so that it can’t be read by a normal user/person. It’s an art of
secret writing; it can also be defined as converting information from plain text
using an algorithm or a cipher to make it unreadable, So that the converted
information can only be read by the person who is having the special knowledge.
The process of encoding is known as Encryption and its reverse process i.e.
decoding it is known as Decryption. Encryption is very useful when it comes to
protecting your confidential data from being stolen.
It is helpful when data is transmitted
over the network, it safe guards you data from sniffers.
When data is needed to be
encrypted over a network, SSL Protocol is used for encryption purpose. SSL
stands for Secure Socket Layer.
Types of Encryption
Symmetrical Key: This type of
encryption is also known as Shared Key Secret. In symmetrical encryption, the
key which is used in the process of encryption, that same key is also used in
the process of decryption. If two parties want to exchange the encrypted data securely,
both of them should have the same copy of symmetric key.
Asymmetrical Key: This type
of encryption is also known as Public Key. In this type of encryption, keys are
generated in pairs, public key and private key. In asymmetrical
encryption key used to encipher is different from the key used to
decipher. Therefore the two partners have two different keys, one is made
public and other one is made private. Let’s take up an example
to understand the concept in an easy way. Suppose, John wants to send a message
to Mike, he just ciphers the message with the public key and sends it to Mike.
Since Mike is having the secret key, he can and decipher the message and read
its content
