kupyna [1/2]

typedef hasher<detail::kupyna_provider<> > digestpp::kupyna

Kupyna hash function.

Ukrainian national standard hash function (DSTU 7564:2014). Designed by Roman Oliynykov, Ivan Gorbenko, Oleksandr Kazymyrov, Victor Ruzhentsev, Oleksandr Kuznetsov, Yurii Gorbenko, Artem Boiko, Oleksandr Dyrda, Viktor Dolgov, and Andrii Pushkaryov.

Kupyna is based on a Merkle-Damgård construction with Davies-Meyer compression function, using an AES-like block cipher as the internal primitive.

Designed to replace GOST R 34.11-94 in Ukrainian government and military applications. The algorithm provides good security margins and competitive performance.

Ukrainian national standard (DSTU 7564:2014).

Type:

Cryptographic hash function.

Output size:

256 / 512 bits

Default size:

none

Exceptions

std::runtime_error

if the requested digest size is not supported

Example:

 // Output a 256-bit Kupyna digest of a string
digestpp::kupyna hasher(256);
hasher.absorb("The quick brown fox jumps over the lazy dog");
std::cout << hasher.hexdigest() << '\n';

Example output:

996899f2d7422ceaf552475036b2dc120607eff538abf2b8dff471a98a4740c6

kupyna [2/2]

template<size_t N>

using digestpp::static_size::kupyna = hasher<detail::kupyna_provider<N>>

Kupyna hash function (static-size version)

Variant of Kupyna with output size specified as template parameter.

Type:

Cryptographic hash function.

Output size:

256 / 512 bits

Example:

 // Output a 256-bit Kupyna digest of a string
digestpp::static_size::kupyna<256> hasher;
hasher.absorb("The quick brown fox jumps over the lazy dog");
std::cout << hasher.hexdigest() << '\n';

Example output:

996899f2d7422ceaf552475036b2dc120607eff538abf2b8dff471a98a4740c6
