Data Encryption !

Data encryption is the act of changing electronic information into an unreadable state by using algorithms or ciphers.

What is Cipher?

A cipher is any method of encrypting text.In addition to the cryptographic meaning, cipher also means 

(1) someone insignificant,

(2) a combination of symbolic letters as twist together of letters for a monogram.

What is Cipher Text? 

Cipher text is encrypted text.

Plaintext is what you have before encryption, and cipher text is the encrypted result.

  Types :There are three basic encryption methods:

  1. Hashing :
  

  The first encryption method, called hashing, creates a unique, fixed-length signature for a message or data set.

  2. Symmetric cryptography:

  Symmetric cryptography, also called private-key cryptography, is one of the oldest and most secure encryption methods.

  3.  Asymmetric cryptography:

  Also known as public key, This type of cryptography uses two keys, a "private" key and a "public key," to perform encryption and decryption.

  

  What is considered sensitive data?

  Ensuring that you use data encryption software or use a secure website beginning with "HTTPS" when you enter personal, sensitive data will help prevent identity theft.

  Examples:

  • Social Security Number
  • Credit and Debit card numbers
  • Bank account and log in information
  • Financial/salary information
    
    

   

  SSL (Secure Sockets Layer):

  It provides standard security technology for establishing an encrypted link between a web server and a browser.
