The Digital Signature Algorithm (DSA) is a public-key technique (i.e., assymetric cryptography) and it is used to provide only the digital signature function, and it cannot be used for encryption or key exchange.
This section provides a tutorial example to illustrate how DSA digital signature algorithm works with small prime modulus p=23 and prime divisor q=11.
DSA stands for Digital Signature Algorithm. It is a cryptographic algorithm used to generate digital signatures, authenticate the sender of a digital message, and prevent message tampering. DSA works by having two keys: a private key owned by the sender and a public key held by the receiver.

Practical Signature Algorithms. ElGamal signature scheme. The private signing key consists of a primitive root g of a prime p and a random exponent x. The public veri cation key consists of g, p, and a, where. = gx mod p. To sign m: Choose random y 2 Z. (p) . Compute b = gy mod p. Compute c = (m xb)y. Signature s = (b; c). mod. (p).
One of the most widely used techniques for achieving this is the Digital Signature Algorithm (DSA). In this article, we will understand DSA algorithm and implement DSA generation and...
