JH Algorithm

Typedef Documentation

jh [1/2]

typedef hasher<detail::jh_provider<> > digestpp::jh

JH hash function.

SHA-3 competition finalist using bitslice design. Designed by Hongjun Wu.

JH is based on a 1024-bit internal state and uses bitslicing technique, which provides resistance to side-channel attacks and good performance on various platforms.

SHA-3 finalist (2012) - did not win but remains a secure alternative.

Type:

Cryptographic hash function.

Output size:

8 - 512 bits

Default size:

none

Exceptions

std::runtime_error

if the requested digest size is not divisible by 8 (full bytes), or is not within the supported range

Example:

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

Example output:

6a049fed5fc6874acfdc4a08b568a4f8cbac27de933496f031015b38961608a0

jh [2/2]

template<size_t N>

using digestpp::static_size::jh = hasher<detail::jh_provider<N>>

JH hash function (static-size version)

Variant of JH with output size specified as template parameter.

Type:

Cryptographic hash function.

Output size:

8 - 512 bits

Example:

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

Example output:

6a049fed5fc6874acfdc4a08b568a4f8cbac27de933496f031015b38961608a0
