What will I learn?

This Coding and Decoding Computer Course helps you quickly understand text encoding, UTF-8, and basic checksums for finding errors. You will learn how letters turn into bytes, check hex data, create and test frames, and see what happens with damaged messages. Using simple examples in common languages, you will make easy checks for correctness, know their weaknesses, and decide when to use better ways like CRCs or secure hashes.

Elevify advantages

Develop skills

  • Put text encodings into practice: change characters, code points, and UTF-8 bytes.
  • Calculate checksums quickly: use XOR, sum modulo 256, and find errors by hand.
  • Create and check frames: [DATA]+[CHECKSUM], spot and record bad packets.
  • Write simple receiver code: read frames, recalculate checksums, deal with errors.
  • Pick integrity methods smartly: checksum against CRC against HMAC for inside protocols.

What our students say

Your classes are perfect. I purchased the one-year package and finally have the chance to follow several topics I'm interested in without having to switch platforms... I appreciate everything you do, I've already recommended you to others...
