Thank you for your support!

Any time! Just finished my cryptography text book Cryptography and Cyber Security in the Department of Defense. Excited to make videos on these

CFB takes the XOR as input into the block and OFB takes from the Cipher Stage as input into the next block.

Glad it was helpful!

Thanks for the sub! Be sure to add me on LinkedIn for job postings

A XOR is a random Initilization vector that is the same length of the plaintext. It is XOR'd (binary math operation) with another set of data. it is not encryption but helps create randomness. See XOR video to see how the math works.

It’s combined with other chapters as the concepts only make sense combined with other areas

Many people use the Linkedin learning SSCP training. I wont have my videos for sscp for a long time due to writing a cryptography textbook at the moment

Any time!

Good idea! Currently building a new curriculum for cryptography and will remake all videos

APR1 is a password hashing algorithm. It's a variation of the MD5. (used in older systems) PBKDF2 is a key derivation function used for securely hashing passwords and generating encryption keys from passwords. It applies a hashing algorithm such as SHA 256 repeatedly to a password and a salt, combined with a configurable number of iterations. Much more secure then APR1. PBKDF2 is still widely used

One takes from the cipher stage and the other from the XOR stage. This output is used for the IV of the next block

also I may be wrong but I think the first time you mention digital certificates, i believe the title it say digital signatures, I may be wrong though.

Glad you like them! Feel free to make any additional requests or make a video and I will put it up

Can you email me looking me up under Paris Wolf

I forgot to add, the Freemasons are known to use the Masonic cipher.

I have not! I don’t own a t.v. at the moment. I will have to take a look at the letter break the encryption, solve the case, and hopefully it will review some secrets

You're very welcome! Be sure to set an appointment if you have any questions!

You're welcome! Feel free to suggest/ make a video

Glad to hear it!

Thanks! just for everyone's reference CIA triad stands for Confidentiality, Integrity, Availability... not the secret agency

Im looking forward to when we can just upload information directly into the brain fy 3077

We must continue to spread the word of these Laws so all know

You are now in charge of all slides

I appreciate that! Hopefully can upgrade the equipment in the near future for higher quality videos

Let me ask him. Can you email me

Thank you Clint Dawg. With a last name like Dawg I wonder if we are distantly related

Glad you like them! I have 1000 more im working on

Fantastic! Be sure to send an invite on LinkedIn

Just wait until we can neural uplink a terabyte of data a second! Fy3024!

Awh yes my nemesis Steve Harvey. In the end only one can be left standing in a suit. #voldermort #harrypotter

I bet they told you those essays were important too…Now we have chat gpt!

Completely unrelated to cryptography WGU. I have been told it just happens to perfectly align. I would recommend taking notes on everything bold if I was taking a test

​@@Professorial_Wolfim confused as to why i see your name on the course chatter recommending people to watch these but you say its unrelated??

@@F1ukez This is a third party website that just happens to teach similar content. Be sure to take notes on every video

You're so welcome! Be sure to pass the test now so I can claim to be the number one teacher with the number one student!

Any hash can have a collision. MD5 would be more common the SHA collision because it’s less complex.

I made these! Send some better questions over and I’ll make another question series called bonus practice questions. Or feel free to make a video and I’ll post it on the channel. Digital signature is used to validate the authenticity and integrity. Digital certificate binds

​@@Professorial_Wolf "Digital certificate" is another way to say "public key certificate." The standard for CAs and certificates were standardized by the International Telecommunication Union in 1988 with the document "Information Technology - Open Systems Interconnection - The Directory: Authentication Framework." This document defined "user certificate; public key certificate; certificate" (in section 1 part 3.3.3) as "The public keys of a user, together with some other information, *rendered unforgeable by encipherment* with the private key of the certification authority which issued it." The only other defined certificate (aside from the CA's) is the "attribute certificate", defined separately in part 3.3.1. Its definition reads "A set of attributes of a user together with some other information, *rendered unforgeable by the digital signature* created using the private key of the certification authority which issued it." Furthermore, the certificate format represented as the ASN.1 data type *includes* the signature as part of the certificate (viewable in section 3 part 8, in "Obtaining a user’s public key"). If a signature accomplishes the goal of validating authenticity, it follows that any definition of an item including a signature can inherit this property as well. No need for bonus questions or a follow-up video to address what I see as a clearly incorrect answer. Accepting what you have marked as the sole answer ignores the ability of a cert to validate the authenticity of the presenting service with respect to an issuer.

the explanation in the video he gave makes sense. He told us the integrity and auth happens with the digital signature that is within the digital certificate...

@@MrOthellonc 9:34 is a very clear "no". Also my longer comment about the original specification introducing certs was seemingly deleted which indicates bad faith. I take teaching seriously and hold those who choose to do so accountable for doing the proper research needed before disseminating information to aspiring students

Glad you like them! Let me know how the test goes, and if there are any additional recommendations for videos to make after

Let me double check and I will get back to you. I believe off the top of my head it was originally stored in the passwd and then moved to the etc/shadow file in later years.

@@Professorial_Wolf yes and you stayed this correctly in one of your other videos. Just don't want anyone to miss that on a Linux test cause it always comes up as a trick question

I do my best

it is a one way math formula and it has to use large key because at the same size their are only so many possibilities for prime numbers/ unique numbers versus symmetric that could use any of the numbers in their math equation. With a one way math formula you are forced to use these prime numbers so the message can not be easily cracked

@@Professorial_Wolf That makes sense. Thank you!

Yes it is a great learning opportunity walking through the fire.

my second video ever created. bad editing! I should remake it... you want to make it and I will post it up?!? I can send you the slides

@@Professorial_Wolf was the answer the bottom image?

Thank you Rob

@@Professorial_Wolf Just took my D334 Cryptography test after watching your series twice and passed by a good margin. I took the pre assessment when I started and was no where near the cutoff. 4 days and done thanks again Wolf!

@@Rob-uj8bo absolutely.highest amount of passes in the I.T. Courses over all instructors

@@Rob-uj8boall you did was watch his videos?

Thank you for your support my liege

So nice of you. Consider making an i.t. Video and I will post it up!
