3 Top Books Every Analytics Engineer to Read

Many of the analytics jobs nowadays are for the financial domain. The top financial domains are Banking, Payments, and credit cards. 
The Best Books are on:

The skills you need to work in data analytics are SAS, UNIX, Python, and JavaScript.  I have selected three books for beginners of data analysts. 

1. SAS best book 
I found one best book that is little SAS. This post covers almost all examples and critical macros you need for your job.

The best-selling Little SAS Book just got even better. Readers worldwide study this easy-to-follow book to help them learn the basics of SAS programming.

Now Rebecca Ottesen has teamed up with the original authors, Lora Delwiche, and Susan Slaughter, to provide a new way to challenge and improve your SAS skills through thought-provoking questions, exercises, and projects.
2. UNIX best book
The basic commands you will get everywhere. The way of executing Macros or shell scripts is really you need. This is a good book so that you can automate…

8 Popular Encryption Methods Real Usage

The process of replacing original data with special-characters is called an Encryption. A highly secured server handles the encryption and Decryption. You need a private key to decrypt the data. Else, you cannot decrypt the data.

Private keys are two types. The sender uses one private key and receiver uses one other private key.

I have given in this post about 8 encryption methods.

 Different Encryption Methods

  1. Classic Cipher
  2. Random Key Generation
  3. RSA Token
  4. Hash Functions
  5. Mac value - Message Authentication code
  6. Key Hash
  7. TLS Protocol
  8. Authenticated Cipher

 1. Classic Cipher

The best example is this kind of algorithm was used in world war -II communication machines.

2. Random Key Generations

One kind of security. They use an algorithm that sends random numbers. People use that number as a password.

3. RSA Token

Every 60 seconds a token is generated. Mostly people use for financial applications. An extra identity mechanism along with user id and password.

4. Hash Functions

It assigns a hash value for each input data value. So that the third person cannot map to original data. The hash value is either 256 or 512 bits.

5. MAC Value

It is also called message authentication value. It takes 3 types of input.

6. Key Hash

Key hash is a little different than the Hash Function. In the case of the Hash function, the reverse calculation of 256 or 512 bits gives a clue to original data. So the possibility of hacking you can find in Hash functions.

So Key Hash came into the picture. The data first go through a MAC algorithm, where it creates Tag called MAC tag. So in the Key Hash process, one additional data transmitted that is called MAC Tag.

One more mechanism is Pseudorandom Functions also called PRFs. Where it calculates random key.

7. TLS Protocol

TLS is a transport layer security protocol(TLS). It works basically as an internet security layer. This works as a middle layer between the Server and Website.

8. Authenticated Cipher

In this case, both encryptions, MAC tags help to check the authenticity of data or transactions.
