Digital signature is the most advanced type of signature that ensures that the content of the document does not change during shipment. A digital signature can be consider a mathematical value, represented by a series of letters. Digital signature certificate in Chennai is one way of verifying the authenticity of an electronic document (e-mail, spreadsheet, etc.).

There is a secure password, which is assign to the holder so that only he can access his signature. DSC makes documents secure and legal.
Reduced time– In order to get a physical signature, the person must be physically fit, which takes longer than necessary. Digital signature certificate in chennai make it seamless to keep his signature on the required documents from anywhere in the world and reduce the time taken in the whole process.

The use of extra time not only saves the digital signature certificate, but also the various costs associated with the physical signature. Some of the costs saved with DSC include ink, paper, and printing, scanning, shipping, tracking and traveling.
Simplify procedures for clients- The client is very tire of inspecting each document, physically examining them and taking a printout of all the documents or visiting any place to put a mark on these documents. The concept of DSC allows clients to do all this at the convenience of their home by attaching DSC to required documents.
Improved business operations- As we discussed in the section above, it is less costly, safer and more secure. All of these things help reduce the time allotted by employees in signing documents and instead keep them in good use.
Working of Dsc
Digital signatures work on the public key infrastructure that protects communication through an unsecured channel using two different cryptographic keys, the public key and the private key. Cryptographic keys are unique pieces of data used to verify the authenticity and integrity of a digital document or message.
The person who creates the Digital signature certificate in Chennai uses a private key to encrypt or lock the data; The key is keep confidential and protects the user’s information from theft or tampering. The public key on the other hand is used to decrypt or unlock data and make the message available to anyone who wants to see it. The keys are mathematical pairs, which work together; A message encrypt by a private key can only be decrypted from a single pair using the public key.
The authenticity and confidentiality of the document is maintain on the basis that the private key of the signing party has not been compromise or stolen unauthorize. If the same happens, the person may create fraudulent signatures in the name of the private key holder.
Creating the digital signature
A dsc must be obtain from a certifying authority to begin signing digital documents so that the receiver can verify the identity of the signing agency. During the digital signing of the document, the sender uploads the document in a program / software, one way of which is to create a cryptographic hash, which is encrypt with the sender’s private key. A document with a cryptographic hash is send over the Internet along with a public key.
The hash value is unique to the hashed document and any changes in that document will lead to a changed hash value, which will help verify the data by the recipient.
Upon receipt the recipient decrypts the hash with the sender’s public key and generates a cryptographic hash of the same document. By comparison, if both hash values are match, the data proves to be authentic and remain unchanged. If the hash values do not match, it is an indicate that the data is damage.
