typedef hasher<detail::whirlpool_provider> digestpp::whirlpool

Whirlpool hash function.

ISO/IEC standard hash function (ISO/IEC 10118-3:2004) based on a modified AES cipher. Designed by Vincent Rijmen (co-creator of AES) and Paulo S. L. M. Barreto.

Whirlpool uses a 512-bit block cipher in Miyaguchi-Preneel construction, with an 8×8 S-box derived from the AES design principles. The algorithm provides excellent security properties and is suitable for applications requiring 256-bit security level.

Standardized as ISO/IEC 10118-3:2004. Recommended by NESSIE (New European Schemes for Signatures, Integrity, and Encryption). Always produces 512-bit output.

Type:

Cryptographic hash function.

Output size:

512 bits

Default size:

512 bits

Example:

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

Example output:

b97de512e91e3828b40d2b0fdce9ceb3c4a71f9bea8d88e75c4fa854df36725fd2b52eb6544edcacd6f8beddfea403cb55ae31f03ad62a5ef54e42ee82c3fb35
