A digital signature is an authentication mechanism that enables the creator of the message to attach a code that acts as a signature. The Digital Signature Algorithm (DSA), developed by the National Institute of Standards and Technology, is one of many examples of a signing 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 ...

Elliptic-curve cryptography. In public-key cryptography, Edwards-curve Digital Signature Algorithm ( EdDSA) is a digital signature scheme using a variant of Schnorr signature based on twisted Edwards curves. [1] It is designed to be faster than existing digital signature schemes without sacrificing security.
In cryptography, a Schnorr signature is a digital signature produced by the Schnorr signature algorithm that was described by Claus Schnorr. It is a digital signature scheme known for its simplicity, among the first whose security is based on the intractability of certain discrete logarithm problems. It is efficient and generates short ...
Public-key cryptography is also used for implementing digital signature schemes. A digital signature is reminiscent of an ordinary signature; they both have the characteristic of being easy for a user to produce, but difficult for anyone else to forge. Digital signatures can also be permanently tied to the content of the message being signed ...
t. e. A cryptographic hash function ( CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with a fixed size of bits) that has special properties desirable for a cryptographic application: [1] the probability of a particular. n {\displaystyle n} -bit output result ( hash value) for a random input string ("message") is.
CMS is used as the key cryptographic component of many other cryptographic standards, such as S/MIME, PKCS #12 and the RFC 3161 digital timestamping protocol. OpenSSL is open source software that can encrypt, decrypt, sign and verify, compress and uncompress CMS documents, using the openssl-cms command. See also
