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?

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.?

@Tollmer 6 жыл бұрын

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 6 жыл бұрын

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.

@kotiprasad5522 6 жыл бұрын

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

@sundeepsaradhi 6 жыл бұрын

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 3 жыл бұрын

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.

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.

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

@sundeepsaradhi 6 жыл бұрын

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 5 жыл бұрын

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.
