Ensuring Digital Signature Lawfulness for Junior Employment Offer Letters

How to eSign a document: digital signature lawfulness for Junior Employment Offer Letter

know though when we explain this technology it appears little complicated let us see how in practice it is so simple that anybody can make use of this signature provided they have made subtle preparatory arrangements now what you see here is a typical email document which is constructed using something like an Outlook or any other software now you have a from address you have a destination address and you have the content now an application like this has a button like this okay sign it also has got something called encrypt so once the person who is sending this has the capability to digitally sign a document just by clicking this button rest of the things are done by the system that is when you click this system the system will calculate the hash value of the content this is the content of course it may also capture the header information which captures the name of the sender etc now that Intel document is hash the hash value is encrypted using a private key of the person provided the system can access the private key and then attach that signature file to this email outgoing email and it dispatches it to the destination address so a fixing a digital signature on an email is as easy as clicking a button similarly if you want to encrypt and if you already have the public key of the addressee if you just click this button or encryption the system will ensure that the whole message is encrypted and indications are here this is for encryption this is for the signing so once you click both these buttons and sign and send the document gets hashed hashed gets encrypted with the private key and the whole document gets encrypted with the public key of the recipient and then it leaves the sender's computer so this is as easy as signing and sending now when it is received at the other end the recipient will see this kind of a covering letter that this message has been digitally signed and encrypted by the sender now if you say continue then like in any other normal case you just read the message as if nothing has happened but if there is an issue the digital signature does not tell you then you get a security warning like this of course the warning may say message has been tampered with which essentially means that either the hash value is not tallying therefore we the system considers that the message might have been tampered with or the public key private key is not matching so the system will either display this security warning or the message as found here this message will come if the signature tell is and this message will come if the signature does not tell you so even before you open the email your system is already verified the digital signature so that you can proceed with either accepting the message as sent by so-and-so or reject the message now what is that the person who receives the message can view what he can view is what is called a digital certificate now actually if you see this certificate kind of a symbol and double-click that you will be able to view this certificate now this certificate says that this particular document has been digitally signed buys an email address identification and the digital ID has not been reworked so that is it is currently in operation and you can rely on that the contents are not altered signature trusted etc etcetera so this is the kind of certificate which is being displayed by the system if you click on the certificate picture and try to view the details now if you if it is a certificate if you click on the tab general then you will say that this certificate has been issued - Rajesh Shankar Maharaja now the name of the person issued by citizenship as Authority validity so what the recipient can see is the name of the person who has sent it and that is how the identification is being taken as authentication now if you want to drill down further into the certificate if you click on the tab of details then you will see further details of the particular certificate such as a serial number is there and there is a signature algorithm sha-1 and RSA algorithm and the issuer's name is there valid from and to and the subject which is the person to whom it has been issued is Navi nine at gmail.com and of course further details of the subject is displayed here which may also contain information such as the corporate identity of the person in this particular case it says via shankar nag raja of EULA consultants you can have a designation director managing that sales manager whatever you want at the time of issue of the digital certificate if it is properly structured you can have the identity of the person along with the designation but what is key to this my say this thing is a email ID because the system will identify the email address rest of it is taken care of by ID and the process similar to the KYC there is no your customer kind of things which banks use at the time the certificates are issued now one more thing you can observe here is if you go to what is called certification path it shows that this particular certificate was originally it comes down from somebody called CCA India to e mudra and from he mudra there are certain internal agencies finally to finish and karna Raj Rob that is this person gets the authority from a mudra and he mudra itself gets the authority from CCA this is called his certification path
