    I have taken many online courses (both free and paid) but I can confidently say that this is by far the most thorough yet simple. I am not a network professional, just a programmer. But your explanation of these concepts has been very clear to me. It's not hard to see your passion for your craft. I think anyone whose job has something even slightly to do with this should definitely take the full course. You are a genius of a teacher.

    Man the way you teach is just amazing, very clear, full of substance and context to help people understand what is going on. i am truly greatful for your videos, you actually managed to ignite an interest for cybersecurity in me which many previous courses i tried failed to do so. Please continue your blessed work!

    Just a small note, by piping the output of echo command to md5sum you also take a new-line character (hex value 0A) into account to produce the MD5 digest.
    Use -n flag with echo command to omit the new line and you'll get the pure MD5 hash of the string "hello", or you can just use "printf" command in stead of "echo".
    P.S.
    Love your content, please keep up the great work you're doing for the community.

      I have some courses on Udemy, but most of that content is available on RUclips, specially with a membership to my channel.
      Alternatively, I have courses on my own platform: classes.pracnet.net.

    Great tutorial Ed. Which made me want to checkout your full course. but I was a bit disappointed seeing the price 297 USD. I am not saying your course is not worth such a high price, but such a high price does make it less accessible to the common public. Maybe lowering the price Or selling it on udemy would increase your sales exponentially ? Anyways thanks for this free video. Cheers.

  • @catmando1786
    @catmando1786 3 года назад +2

    So let me check this. If I send you a message and the hash reads 11111 and you know which algorithm I used then you can decipher my message in reverse, yeah? But what about collisions? In theory my message could be the other message that also contains 11111.

    • @PracticalNetworking
      @PracticalNetworking  3 года назад +1

      11111 is only a 5-bit hash (5 digits, 1 or 0 each digit). That means there are only 64 possible hash digests. Which means there will be A LOT of collisions. All the modern hashing algorithms use much, much higher bit length. MD5 (often considered the least secure hashing algorithm) is 128 bits.
      I unpack collisions in more detail starting from 07:50 onwards.
