Ensuring Digital Signature Lawfulness for Technical Support in Mexico

How to eSign a document: digital signature lawfulness for Technical Support in Mexico

a very good day to my Cyber Law lecturer and I am the insurance son of ramu my mentor's number is 01821f 2044 and now I'm going to demonstrate about our practical task one and here is the objective and the question so the question is about the digital signature is a mathematical technique used to validate the authenticity and the Integrity of a digital message so the digital signature is equivalent and a handwrited signature digital signature can actually be far more secure the purpose of the digital signature is to prevent the tempering and impersonation in digital Communications in many countries including the United States digital signature have the same legal significance and traditional forms of science document the United States government now publishes electric electronic version of budgets law and Congressional bills with digital signature so part one using digital signature in this part we will use a website to verify a document signature between Alice and Bob Alice and share of a pair of private and public RC Keys each of them uses their private keys to sign a legal document they then send the document to each other both Alice and Bob can verify each other's signature with the public key they must also agree on shared public exponent for a calculation so this is a table one and public RSA key and private RSA key and public exponent the number is one zero zero zero one so for the step one Alice signs a legal document and send it to Bob using the public keys and this is the RS public keys and priority is showing the table one above now what we'll have to verify lsdg the signature in order to trust the authenticity of electronic document and now we are going to click here let me open in two way first [Music] and so we must here enter the public keys and the private keys so for the public key go for your popular public keys and so for the private key also we repeat the same method we gonna copy the private RSV key from the table one shows sorry the table one even Ctrl C for the copy and Ctrl V for the base for the text so this is the text at least digital signature so we're gonna copy this and paste this and for the step three now what can verify the signature by clicking the verify button near the bottom center of the upside whose signature is identified so now we're gonna click the verify button so the tag is showing the name helis so that's all from me Madam and the next steps will be shown by my group members thank you so my name is darker and my Matrix number is 0 1 the d21f 2060 now I am going to talk about the following step which is step 3 generate a response signature Pope receives and verifies additional electronic document and digital signature now Bob creates an electronic document and generates his own digital signature using plywood RSA K table one so this this is a RSA encrypted so the exponent is correct here and the public wonders and private exponent is correct here so we just need need to copy paste this open this from here and paste this at here 25 verify it's our way to press this so yeah it's verified so it says here is box and yeah that's all from me good evening my name is shankari daughter of Shankar number Matrix is zero one dat two one F two zero five five today I am going to demonstrate on how to create your own digital signature for step one generate a new pair of RAC keys go to the website tool and generate a new set of RSA public and private keys so here is the RSA website tool next delete the contents of the boxes label public modules private modules and text just use your mouse to highlight the text and press the delete key on your keyboard so what we should do is delete the public modules and private modules so let's delete this first all right so next make sure the public exponent box has one zero zero zero one so let's check this public exponents we already have one zero zero zero one value so next is generate a new set of RSA keys by clicking the generate button near the button right of the website so let's go to the bottom and you can see the general button so click that so your public modules and private modules will change next copy the new keys in table 5. so copy this public modules and paste these in public keys next same goes to private all right then now type in your full name into the box label text and click signs so let's type my name here go to bottom and click sign so as you can see your text is also change so yeah next personal digital signature so as you can see here is the personal signature um personal digital signature so click this copy and paste this over here so yeah that's all from me Madam thank you well thanks to my Lab Partners and shankari who's demonstrate the part one and part two elaborately now I would like to demonstrate the pottery which is exchange and verify digital signatures the command is now you can use this digital signature which is uh that we previously used in part one and part two uh the step one is exchange your new public and private key in table 5 with your Lab Partners so I would like to uh check my Lab Partners public and private key and to see their lab uh I mean their digital sign in my computer so without any delay let's get into the process okay now uh I would like to go to the website first RSA encryption calculator so here uh public modulus and private exponent will be remain uh plain you know plain box and the public exponent will be uh one zero zero zero one remain the same so now I would like to uh copy and paste my friend's public and private key so here are the public key of my friends one just copy and paste here okay the second is private exponent private exponent yes cop B and paste here also okay the last one is text so here are the text personal digital signature which is my friend's one just call P and paste uh text box here so here are the public uh public modulus private exponent and text from my friends one so I would like to verify by clicking the verify button down here so we will verify my friend's name shankari daughter of Shankar in my computer so that's all now we would copy these and based in the word that one is given oh no yeah I mean here waste okay so this one is my partner so that's all from me that's all from us thank you
