A digital signature is actually a mathematical formula or number which can be used to verify the identity of the sender. While digital signatures look and work just like handwritten signatures, they are much more secure and transparent. When digital signatures are used to verify documents, the risk of impersonation and tampering in the digital world are minimized.
No matter what type of digital document you might be working with, a digital signature can be used to identify the origin and status of the document. You can also use your digital signature on a document to give your consent.
Due to its benefits, IZpDS digital signature, in some countries, is given the legal status of handwritten signatures. This means, by providing your digital signature on a document, you are legally bound with your words.
Working of Digital Signatures
When you dig deeper into the working principles of digital signatures, you will find out that they are generated with the help of asymmetric encryption. This method uses a secure algorithm to generate a pair of keys, which is linked with each other with the help of a mathematical formula. One of these keys is public, and the other one is private.
Private key of the signer is used to encrypt the digital signature and all the data related to it. On the other hand, the receiver has to use the public key of the sender in order to decrypt the message.
However, if the public key of the sender does not open the document, you should believe that the document has been tampered with, or the sender is not legitimate. This is the whole authentication process of digital signatures.
When you are using digital signatures, you must keep your private key secure and away from the reach of any unwanted person.
