Do IT professionals need to learn encryption?

Question

Programming

Hello everyone! I started to study programming and decided not to stop at the superficial level, in parallel to dig further, to computer science... to find out how everything works at the hardware level. still normal) and about various ways of encoding data. Now I stopped at the moment where it tells about the principle of how barcodes work. side and how much?

Answer 1

If you're interested, why not take a look? The internal state and internal, personal interest are the highlight of any person. The only problem is that everyone is taught not to pay attention to it. You see, “the world doesn’t need this”, “you still won’t succeed”, “you’re not strong enough in mathematics” and “in general, it’s better to go to work.”
There is an interest, a hunger for information from this area - grab it and dive head first. And the points of the past and the present can be connected only in the future. Steve Jobs once said this.
However, do not listen to my answer. Listen to yourself.
Good luck.

Answer 2

What you are learning is not encryption, but a basic understanding of how information is stored and transmitted.
Read for a couple of evenings. Morse code is around here somewhere.
There is still a long way to go before serious work with cryptography.
Read.
Understand at least the basic ones - number systems (binary, octal, hexadecimal), encodings, Huffman codes, Reed-Solomon codes,

Answer 3

The basic principle is yes. Symmetric and asymmetric encryption.
Digging deeper is up to you.

Answer 4

You need to study everything (including encryption) only if you need it. It is enough for an IT specialist to know that encryption exists and what it is, this knowledge is given in any IT university. How it specifically works needs to be known only to those who are specifically involved in this (as a rule, only this and nothing more).
