DSA

DSA, or Digital Signature Algorithm, is a cryptographic method used to verify the authenticity and integrity of digital data or messages. It creates a unique digital signature using a private key, which can then be checked by others with a corresponding public key. This process confirms that the message truly originated from the claimed sender and hasn't been altered. DSA is widely used in secure communications, such as signing documents or emails, ensuring trust and security in digital interactions without revealing sensitive information.
