## What is DSA algorithm?

- A digital signature
**algorithm**(**DSA**) refers to a standard for digital signatures. It was introduced in 1991 by the National Institute of Standards and Technology (NIST) as a better method of creating digital signatures. Along with RSA ,**DSA**is considered one of the most preferred digital signature**algorithms**used today.

## What is the Digital Signature Standard (DSS)?

**Digital Signature**Standard ( DSS ) is the**digital signature**algorithm (**DSA**) developed by the U.S. National Security Agency (NSA) to generate a**digital signature**for the authentication of electronic documents.

## What is digital signature?

- A digital signature is a mathematical technique used to
**validate the authenticity and integrity of a message, software or digital document**. It's the digital equivalent of a handwritten signature or stamped seal, but it offers far more inherent security.
