What is a digital signature

A digital signature is a cryptographic tool that is used to verify the authenticity of a digital document or message. It is created by a partner, such as a certifying authority, to ensure that the document has not been tampered with and comes from a valid source. With a digital signature, you can easily create and insert electronically signed PDF documents or other digitally-signed files.

There are several methods available to obtain a digitally-signed document. One option is to get a digital signature certificate from a certifying authority, such as eMudhra, online. These certificates can be used to sign documents without the need for a physical signature. Another option is to use a C program or Microsoft Windows to create a digital signature.

When creating a digital signature, the signer uses a private key from their certificate to encrypt a hash of the document or message. This encrypted hash is then attached to the document or message, along with a copy of the signer’s public key and a digital certificate. The recipient can then use the signer’s public key to decrypt the encrypted hash and compare it to a newly computed hash of the received document or message.

By verifying the digital signature, the recipient can ensure that the document or message has not been altered since it was signed and that it came from the expected signer. This provides a level of assurance that the document or message is genuine and can be trusted. It is a way to ensure the integrity and authenticity of electronic files.

Using digitally-signed documents has many advantages. They are legally valid and widely accepted by courts and other auditing authorities. They can be used in various industries and sectors, such as finance, healthcare, and government. Digital signatures also provide a more efficient way to sign and verify documents compared to traditional paper-based processes.

In conclusion, a digital signature is a valuable tool for ensuring the integrity and authenticity of electronic documents and messages. Whether you obtain a digital signature certificate from a certifying authority or use a program to create one yourself, digital signatures offer a secure and reliable way to sign and verify documents in the digital age.
