Functions
void	keccak256 (const uint8_t *in, size_t inlen, uint8_t out[32])
	Compute the Keccak-256 hash of a given input buffer.

Detailed Description

Keccak-256 (SHA3 variant) hash function for Ethereum.

Provides a function to compute the Keccak-256 hash of an input buffer, producing a 32-byte digest.

Note

This implementation is suitable for Ethereum-style hashing.

Function Documentation

keccak256()

void keccak256	(	const uint8_t *	in,
		size_t	inlen,
		uint8_t	out[32] )

Compute the Keccak-256 hash of a given input buffer.

Parameters

[in]	in	Pointer to input data.
[in]	inlen	Length of input data in bytes.
[out]	out	Pointer to a 32-byte buffer where the hash will be stored.

Note

The output buffer must be at least 32 bytes long.

This function implements the Ethereum variant of Keccak-256.

Compute the Keccak-256 hash of a given input buffer.

Parameters

[in]	in	Pointer to input buffer.
[in]	inlen	Length of input buffer in bytes.
[out]	out	Pointer to a 32-byte buffer to store the hash.

Note

The output buffer must be at least 32 bytes long.

This is Ethereum's Keccak-256 (pre-SHA3 standard padding).
