A digital signature is an electronic copy of a signature which can be used to verify the identity of the sender of a message or the signer of a document, and also guarantee that the original content of the message or document that has been sent is consistent. Digital signatures are easily transportable and cannot be duplicated by someone else. The capacity to ensure that the original signed message arrived means that the sender cannot easily disclaim it later.
Digital Signature Certificates (DSC) is an electronic format of certificate like a driving license, passport etc. These Certificates serve as proof of identity of a person for a certain purpose; e.g, a Passport identifies someone as a citizen of a specific country; who can lawfully travel to any country. Just like that, a Digital Signature Certificate can be presented electronically to prove your identity.
A DSC verifies your identity electronically. It comes with a high level of security for your online transactions by guaranteeing total privacy of the information exchanged using a DSC. By using DSC you can encrypt information so that only the intended recipient can read it. You can digitally sign data to ensure the recipient that it has not been changed in transit, and also verify your identity as the sender of the message.
Legally valid DSC are only issued through a Controller of Certifying Authorities (CCA), Govt. of India, licensed Certifying Authorities (CA), such as Signatech. Signatech, a Certifying Authority (CA) licensed by CCA, offers guarded digital signatures through different options designed to suit individual as well as organizational needs..
A Digital Signature Certificate very smoothly links the identity of an individual/device with a pair of electronic keys – public and private keys – and this alliance is endorsed by the CA. The certificate includes information about a user’s identity (for example, their name, country, email address, Pincode, the date the certificate was issued and the name of the Certifying Authority that issued it).
These keys work hand in hand, one can not be used without the other. They are used by browsers and servers to encrypt and decrypt data regarding the identity of the certificate user during the exchange of information processes. The private key is saved on the user’s computer hard disk or an external device such as a token. The user reserves control of the private key; it can only be used with the issued password.
The public key is disseminated with the encrypted data. The authentication process fails if either one of these keys is not available or do not match. This means that the encrypted data cannot be decrypted and therefore, is inaccessible to unauthorized parties.
