Digital Signature Algorithm (DSA)

The Digital Signature Algorithm (DSA) is a mathematical method used to verify the authenticity and integrity of digital messages or documents. It creates a unique digital signature using a private key, which can be checked by others with the corresponding public key. This process ensures that the message truly comes from the claimed sender and hasn't been altered. DSA is commonly used in secure communications, online transactions, and digital certificates to confirm identity and maintain data security without revealing secret keys.
