Nowadays, all government services are being received through “e-governance” people, in addition to pan card, voter cards, Aadhaar card, there are many types of proofs for which you had to go to the government offices of your district, Such as income-caste-residence etc. certificate etc. Earlier these certificates used to be signed by the officials, but now this work is being done by Digital Signature.

Before knowing about the digital signature, some government officials understand, the earlier certificates were prepared in a manual manner, in which the applicant filed the application and found the necessary attachments and submitted it to the office, then his application For the test, the inspection officer or employee was served, the level of the test depends on what type of certificate you have applied for. After verification, he comes back to the certificates office and signed by the competent authority and obtained from the applicant.

But now this is not the case, now is the time. Through this process of “e-governance”, all this process has become very simple, through it all types of certificates are prepared through an internet portal. If seen only The entire process is completely paperless except the application and the prepared certificate. It is purely a digital form of certificates. In this, the entire inquiry process is done on the Internet portal itself. In this, digital signatures are used by officers and employees at all levels of the verification process. Verification of all these certificates can also be done very easily through the portal.

A digital signature or signature is a type of computer code that can only be used by a large number of people, which requires either a user ID and a password to use, in addition to a dongle is used elsewhere. Which is a type of PenDrive-like device, like we told you to create a PenDrive first and make your computer’s password. It is the same type of arrangement, i.e. digital signature will only be done by someone who has both these things. Just as paper certificates were manually signed, digital signatures are done on electronic certificates. They are legally valid.

How DSC works?
It generates two keys using public-key algorithms such as RSA which are Private and Public. And both these keys are mathematically linked. With the help of Signing Software to create Digital Signature, one way Hash of electronic data which is to be signed. Then the hash is encrypted with the help of Private Key. The same encrypted hash and other information associated with it such as hashing algorithm to be known as a digital algorithm.

Here we encrypt the empty Hash instead of the entire message because with the help of Hash Function we can convert an arbitrary input into a fixed-length value which is smaller than the normal. This saves time because Hashing is much faster than Signing.

The value of Hash is unique if we look at its Hashed Data. If anything changes in that data, even if a character is manipulated then only some other value will be shown in the result. This feature enables others to validate the integrity of the data using the public key of the signer to decrypt the hash. If the decrypted hash matches with another computed hash then it proves that there has been no change in the data. And if both Hash’s data do not match, then it is possible that some changes have been made in the data, it cannot be trusted anymore.
