Cryptography Handbook For Beginners

Let’s start with a question

You Enter your office and you need to enter a 4-character password

The keypad has 10 digits

“How many password possibilities are there? “

Using basic math, The answer is 10 to the power of 4 ( you multiply 10 by itself 4 times )

This question actually leads to some basic crypto terminology

  • The secret key complexity is 10 digits from 0–9
  • The key length is 4 characters
  • The keyspace, the number of possibilities is 10,000 combinations

When we deal with cryptography, the art of hiding things, anyone knows what is the cipher algorithm that generated the cipher message. But the attacker/hacker tries to find out what is the secret key
