    en.wikipedia.org/wiki/Digital_signature

    Definition. A digital signature scheme typically consists of three algorithms: A key generation algorithm that selects a private key uniformly at random from a set of possible private keys. The algorithm outputs the private key and a corresponding public key. A signing algorithm that, given a message and a private key, produces a signature.

    en.wikipedia.org/wiki/Digital_Signature_Algorithm

    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. In a public-key cryptosystem, two keys are generated: data can only be encrypted with the public key and encrypted ...

    The sender uses PGP to create a digital signature for the message with either the RSA or DSA algorithms. To do so, PGP computes a hash (also called a message digest ) from the plaintext and then creates the digital signature from that hash using the sender's private key.

    en.wikipedia.org/wiki/Code_signing

    Code signing. Code signing is the process of digitally signing executables and scripts to confirm the software author and guarantee that the code has not been altered or corrupted since it was signed. The process employs the use of a cryptographic hash to validate authenticity and integrity. [ 1] Code signing was invented in 1995 by Michael ...

    en.wikipedia.org/wiki/Digital_Signature_Standard

    The Digital Signature Standard (DSS) is a Federal Information Processing Standard specifying a suite of algorithms that can be used to generate digital signatures established by the U.S. National Institute of Standards and Technology (NIST) in 1994. Five revisions to the initial specification have been released: FIPS 186-1 in 1998, [ 1] FIPS ...
