It’s always been a great challenge to send the sensitive data in a more secure way so that the hackers cannot decode even if they trap the entire data transmission. To overcome this issue, several encryption algorithms have been generated and the concept of encryption is not new to the present world. It actually started in 500 BC with the Spartans using the technique of rearranging the letters position within a text.
Encryption is the ability to transform plaintext, the data can be ready by anyone to cipher text, that can be read by an intending person on applying the decryption key. In recent times, there have been several encryption algorithms been written by data security professionals to ensure high level security for the data transmission.
From 500 BC to 2010 AD, several encryption techniques were available for the users to ensure the data privacy and few mostly used encryption techniques include Caesar Cipher, Frequency Analysis, Polyalphabetic Cipher, Jefferson Wheel, Engima Machine, Cryptologic Bombe and Data Encryption Standard 56 (DES 56). Currently, the most popular encryption algorithm, advanced encryption standard (AES) is used by the companies in order to transmit secure data over a network.
Using the Brute Force hacking technique, it would roughly take around 77,000,000,000,000,000,000,000,000 years for entire population on earth to crack an encryption key of 256 bit.
As nothing is guaranteed in this present technical world, so experts suggest that it is better to select a strong password that is generated by combining numbers, special characters, symbols and mixed-case letters to stay safe from hacking.
