The Digital Signature Algorithm (DSA) is a public-key cryptosystem and Federal Information Processing Standard for digital signatures, based on the mathematical concept of modular exponentiation and the discrete logarithm problem. DSA is a variant of the Schnorr and ElGamal signature … See more The DSA works in the framework of public-key cryptosystems and is based on the algebraic properties of modular exponentiation, together with the discrete logarithm problem, which is considered to be computationally … See more The DSA algorithm involves four operations: key generation (which creates the key pair), key distribution, signing and signature verification. See more • Modular arithmetic • RSA (cryptosystem) • ECDSA See more In 1982, the U.S government solicited proposals for a public key signature standard. In August 1991 the National Institute of Standards and Technology (NIST) proposed DSA for use in their Digital Signature Standard (DSS). Initially there was … See more Below is a list of cryptographic libraries that provide support for DSA: • Botan • Bouncy Castle • cryptlib See more • FIPS PUB 186-4: Digital Signature Standard (DSS), the fourth (and current) revision of the official DSA specification. • Recommendation for Key Management -- Part 1: general, … See more WebThe following values are accepted: 'binary' (default), the signature is the raw concatenation of r and s. It is defined in the IEEE P.1363 standard. For DSA, the size in bytes of the signature is N/4 bytes (e.g. 64 for N=256 ). For ECDSA, the signature is always twice the length of a point coordinate (e.g. 64 bytes for P-256).
