[@hitendusseja6615]

Nice video sir Nicely explained

[@ravivarma6046]

Thank you sir ... superb 👌👌 explained

[@abishaa6691]

Very nice explanation...thank you sir

[@Tollmer]

The best explanation on youtube. Thanks for sharing your knowledge :-) But one question i have. The value of opad and ipad are constants? And if they are constants, are this constants the same for every hashfunction?

[@sundeepsaradhi]

hi yes these values are not constants they may vary depending on algorithm. thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.

[@mayurPrmr1182]

Great explanation 😀

[@ganeshjaggineni4097]

NICE SUPER EXCELLENT MOTIVATED

[@youknowwho3377]

Very well explained..... Thank you 😃

[@zsurdo]

Excellent explanation, but I have a question with the condition (0 < K < b) wich is the value for b, how many bits has b? or how many bits I need to add on the left of k.?

[@shitang8031]

HI sir, many thanks for your video! I would like to ask if i use SHA256 and I will get a 256 bits output. However, if my b bit is smaller than 256, should I pad anything on it? why I cannot just compute the hash function and get 256 bits string as my output?

[@pallavithakur3395]

Really a huge thank u sir... u saved 12 marks for me...

[@banderallogmany1912]

Really thank you, you saved my time. In 09:50 you may meant pad to b bits.

[@nehalsingh785]

awesome tutorial sir

[@Babulal-kq2ib]

In mac also we used key here also not getting the difference between two.

[@ambicabanchode2581]

excellent work sir

[@arian7472]

Very Good but always try to clarify how each peer generate the key then shared also if you can mirror that to a complete VPN negotiation using IKE v1 and 2 it will be very good the key creation and exchange is very important and missing with all who study vpn

[@ramolashishupal4783]

Very helpful videos sir Thank u sir

[@sakinavetiprathushya5578]

Sir is there any difference in this Hmac algorithm compared to remaining algorithms

[@rajeshawal772]

Thank you so much!

[@21day5]

nice explanation

[@Raj_Patel21]

Very nice explanation

[@ghufrankhan8458]

Thank you for your help sir

[@FunVibesDose]

anybody tell me if k=0011 b=8 what is the value of k+ , si, ipad, opad, s2.

[@swaroopkv4540]

Repeat b by 8 times means?

[@amudhapi6492]

What is the purpose of hmac ???

[@shivamnandha1999]

Very useful......

[@bellalmahtab8220]

Sir how u insert these no to the iPad or opad

[@siddanatibhargav3070]

Y r u don't make videos on idea n cast128 blowfish Make videos for these they r useful for us

[@pawankesharwani7831]

what is ipad,opad and define how it is use b/8 times.

[@pasindusiriwardana5242]

you can find the answer below . See Domenico's answer

[@arian7472]

many thx sir just you said many times that HMAC not use key, but the key has a main role here, can you explain i know MD5 and SHA is just integrity mechanism and HMAC is modify of them by adding a key to avoid Man in the middle

[@sreenaunnikrishnan3135]

Sir please explain security of HMAC

[@dinnusebastian4615]

Is any video on mac (messsage authentication code) is available here..

[@sauravkumar-yh7tv]

What is the length of 'b' bits? And What mean b/8?

[@sundeepsaradhi]

hi saurav length of b depends on plain text. thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.

[@domenicorodilosso5465]

if the length of K+ is for example 128 bits, in order to XOR this value with ipad or opad value, we need K+ and ipad (or opad) of the same size. So we know that the ipad's value is 00110110, so 8 bits, in order to reach the size of K+ (128 bits), we have to repeat this value (00110110) 128/8 = 16 times. At the end of this process K+ and ipad will have the same length and they will can be xored.

[@pasindusiriwardana5242]

@@domenicorodilosso5465 nice

[@thakurneelima441]

why we need to repeat ipad and opad fpr b/8times

[@sivabhaskarreddygonapati8824]

i cant understand b/8 with ipad amd opad .Can u tell me about it??

[@DrIBLal]

Will you please explain ipad and opad with more clarity

[@surajdaiya6392]

Yaa ,can you explain opad and iPad in details with examples

[@sundeepsaradhi]

Hi lal These are the predefined values to be used in algorithm. Thanks for your support and interest towards our channel and share our channel with your friends. Keep following our channel.

[@siddarthakolani5796]

Nice explanation sir In this what if K value is equal to B, then there won't be k+? Then how we should take k+ value for further process??

[@zsurdo]

when K=b you have K+. this is the condition. in my case.. my question is how many bits has b.....? to condition will be positive.

[@shruthikamalk4915]

What does b/8 mean?

[@rajasreenair6496]

Well explained. Thanks a lot sir

Sir is there any difference between HMAC algo and efficient implementation of HMAC?

[@NitishRaj]

Yes. Efficient itself depicts.

[@bhavyaparikh667]

BEST!!!!!!

[@balashivuduu2101]

Sir explain Elliptic curve cryptography algorithm

hi bala thanks for your interest towards our channel. soon i will try to upload it.

[@kotiprasad5522]

Can you please kindly tell the difference between the authentication algorithms and encryption algorithms with a real time example in simple words?

[@sundeepsaradhi]

hi prasad Authentication algorithms are meant for verifying the sender and to acheive integrity that mean the receiver should know that the data has not been modified during the transmission. Encryption algorithms are meant for providing the security for the data that is converting plain text to cipher text. Hope your doubt has been clarified.

[@a.yashwanth]

If you receive a post and it's from the president then you will verify the sign to make sure. That is authentication. If you send a message to someone using WhatsApp then no one can understand the message other than you 2. That is encryption.

hi nice easy to understand sir upload video for sha1

[@sundeepsaradhi]

hi muniyegowda i have uploaded sha-512 and it is one of the variant of sha-1 the only difference is the output hash code.the implementation is same so once go through the video and let me know if you find any difficullty.
