What Is Digital Signature?

A signature is known to signify an agreement. If you sign something, it means you are giving your consent to it. When talking about the use of a signature in a bank while signing checkbooks, it again shows our consent. But these signatures can also turn into havoc when duplicated. This can be a little scary as such duplicate signatures have the capability of robbing you of your hard-earned money. But one way you can prevent this scam of duplicate signatures is by using Digital Signature.

Using the technique of digital signature, you can verify all the documents and check if it is genuine and authentic or not. The framework of a digital signature is such that it can easily determine if there is any meddling done to it. This way you get the apt details on the identity, origin, and status of your online document.

How Digital Signature Works

The technology of digital signatures is based upon asymmetric cryptography, a.k.a., public-key cryptography. It develops 2 keys with the help of a public key algorithm like RSA, being public and private. These keys are linked mathematically. By using the signing software that makes it, the e-form, if a signature is to be made, is created by a one-way hash. This hash is then encrypted by using the private key. 

Other alike encrypted hashes and other useful data such as the Hashing Algorithm are identified as the digital signature. In this, the empty hash is encrypted except for the whole message. This is because of the hash function any general input can be translated into a set length value. This preserved time as hashing is quicker than signing.

The value of the hash is special if we focus on its hash data. If modifications are made to it, even after manipulating a character, some other value will appear in the result. Using this option anyone can check the information’s integrity by utilizing the public key by the signatory to decrypt the encrypted hash. 

If it matches with the other automated hash, you will get evidence that there are no modifications in the details. And if the computed hash and the decrypted hash do not match, then there can be a chance that modifications have been done to the details, and it’s not to be trusted.

Digital Signature Example

Whenever you put in your details (your id and password) to log in to any website, the data that you enter starts working as your digital signature.
