SHA 512 (SECURE HASH ALGORITHM)
1) PAD WITH THE BITS 100..... UNTIL LENGTH OF PLAIN TEXT REACHES 128 LESS THAN MULTIPLE OF 1024 BITS
2) APPEND 128 BIT REPRESENTATION OF ORIGINAL PLAIN TEXT MESSAGE SO THAT LENGTH EQUALS TO MULTIPLE OF 1024
3) INITIALIZE 8 BUFFERS OF SIZE 64 BITS EACH TO STORE INTERMEDIATE RESULTS AND FINAL HASH CODE.
4) PROCESS EACH 1024 BIT BLOCK IN 80 ROUNDS.
5) OUTPUT IN BUFFERS IS THE 512 BIT HASH CODE

sir , you explain very clearly and salute to your efforts. You take print out of all diagram and explain it . I wish professors in engineering colleges in India should be like you.

@ianyoung5857 5 лет назад

Studying for a cryptography final and this was really helpful. Thank you for providing your explanation of SHA-512.

HATS OFF SIR towards your DEDICATION HATS OFF!!!!! Thank you so much for simplifying and teaching us the contents thank you!!!!!! BEST TEACHER EVER!!!

@sureshg6981 4 года назад

Superb Sir! This is the first time known about SHA algorithm. Now i got concept and process. Thanks for giving detail explanation. Thank you sir.

@jaydippatel363 4 года назад

Kindly Note: Digest Length of SHA-1 is 160 bits, not 128 bits.

@mohduzair5607 3 года назад

exactly

@mridulhoneysharma 4 года назад

Sir you must reduce the length because many of student watch it during exam we don't have time to view one hour video for just one topic.... Even if we increase the playback speed its still to long...

@kutubuddinmondal7937 5 лет назад

Sir, please provide your notes which was used by you during the explanation,so it will be more helpful for us,many of the diagram are not provided in any of the books,and explanation was really nice,many of the topic are not in the book also....there is a little bit of explanation in the book.so sir please try to provide the notes Thank You

@balukoduru9960 4 года назад

Hi Sir , thank you for the explanation. does it means do we have possibility to extract plain test from hash code? As Hash code will be tightly coupled to each bit of plain test?

@ashenafielias9617 3 года назад

Very important video, Great thanks for your dedication, Sir, would you please upload a video on SHA-1?Algorithm

@aidaazizi2238 5 лет назад

What is the round function in SHA algorithm? what does the round function do? what operation does it do on initialization vector which we call it buffer and 1024 bits?

@jagadishsairam7426 3 года назад

Wow, your video is awesome. very indepth explaination. But i need one more video with example of message "I love india" or some "hex value message" from sender node to receiver node. If you explain the same concept with example, that would give next level dimension to understand the concept to core.

Sir, Please upload the video lecture wise ie. request to provide numbers to the lecture. It will be helpful to both the students who are either learning this from very basics or want to switch from one lecture to another.

@sundeepsaradhi 6 лет назад

hi sumeet i am uploading the videos in order and if you watch the play list it will be arranged in a stack order that means latest video will be uploaded in the beginning.

@niharikasaikrothapalli592 6 лет назад

SHA-1 gives an output of length 160 bits. In the explanation it is mentioned as 128 bit output.

@sundeepsaradhi 6 лет назад

hi niharika sai first thing this algorithm is not SHA-1 but it is SHA-512 The output of this algorithm is 512 bit hash code and in the second step we have to append the 128 bit representation of a plain text. and it is not the hash code. hope your doubt has been clarified.

@niharikasaikrothapalli592 6 лет назад

Sundeep Saradhi Kanthety At 4:26 it's about SHA-1

@sundeepsaradhi 6 лет назад

Hi Niharika nice observation and really i didn't observe that and i am sorry for the mistake and you are correct it should be 160 bit. thanks for correction.

@Sasidhar_Sam 4 года назад

Hello, your explanation is really good. But in this lecture, it is mentioned that the hashing algorithm is used to authenticate the message sent, but in my view hashing techniques are used to check the integrity of the message but not to authenticate the message. To enable any authentication Key (asymmetric or symmetric) concepts will be applied. Please clarify my question.

@bree9895 Год назад

yes hashing is for integrity

@ashutoshkalecompgeek 6 лет назад

I'm following this whole series and genuinely one the best video on youtube but i have few suggestion : 1) instead to holding a paper in front of camera, better add the pic into PPT file and then screen-record it and at the end append to screen recorded video with the video.. 2) Add numbering to videos sometimes it make confusion for the viewers where to begin and end :)

@sundeepsaradhi 6 лет назад

hi ashutosh kale you are correct and i will agree with you and from the next video i will change this format. thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.

@supriyaaddanki9025 3 года назад

sir I got SHA-1 for my exam can I write the same architecture of SHA-512 and just mentioning the output as 160bits ..?

@karunaprasad1304 6 лет назад

Sir ur videos are very good with clear explanation if possible please explain. What is message digests with clear explanations

@sundeepsaradhi 5 лет назад

Hi Karuna Thanks for your interest and coming to message digest it is an authentication technique. User will calculate fixed length value from the given plain text and it will be appended to the plain text and sent to the receiver so that at the receiver end the same process will be done for finding fixed length value from message digest and it will be compared with the appended value, if both matches then it seems no modification during transmission. If both are not equal the there might be modification during transmission. Hope your doubt has been clarified.

please post something on elliptic curve cryptography

@ketankumar5689 4 года назад

Sir, is it almost same as MD5 algorithm ?

@yashalekar7205 6 лет назад

but sir sha1 produce output 160bit and md5 produce output 128 bit....

@KartikayKaul 5 лет назад

md5 produces 32 bit output

@ashishgupta5491 5 лет назад

hi siddharth i will agree with that.but it would be better for the slow learners if we repeat the topic twice. thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.

@Achu12321 4 года назад

what is the 128 bit representation of message. how to generate it?

@Kino-Imsureq 6 лет назад

when you are padding the bits, should you pad 100 zeroes or pad it in a way of concatenating text?

@sundeepsaradhi 6 лет назад

hi padding means adding dummy bits that makes difference in length for our algorithm. thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.

@balajisingh3442 2 года назад

How to pad if length of plaintext is 1020 bits

@abhishekmuddu8405 3 года назад

those 80 constants are not randomly generated using ant pseudo random number generator.....those are genrated by converting the "fractional part" of the cubic root of the first 80 prime numbers ( 2,3,5,.....409) into HEXADECIMAL format

Hi Sir You are very good teacher I need Solution for how can I convert rolling code 512 digits pincode to 128 digits outcode

@aadishgoel 6 лет назад

Sir, Great video but just a correction needed. Rotation Functions are not according to NIST Standard that should be Rotate(A) = RotR28(A) XOR RotR34(A) XOR RotR39(A) Rotate(E) = RotR14(E) XOR RotR18(E) XOR RotR41(E)

@sundeepsaradhi 6 лет назад

hi goel thanks for the correction keep following our channel and support me by correcting my mistakes.finally viewers should be benefited. Thanks again for the correct information.
