SHA3_256ByteArray

Cryptography

Description

Computes the SHA3-256 digest of a byte array and returns it as a fixed-size TPLSHA256Digest value of 32 raw bytes. The hash runs through the built-in FIPS 202 Keccak implementation shared with the SHA-3 stream functions, using the SHA-3 domain suffix and a 136-byte rate; an empty array returns the digest of the empty message

Syntax

Delphi

Function SHA3_256ByteArray(Input: Array Of Byte): TPLSHA256Digest;

Return values

	The SHA3-256 digest as a `TPLSHA256Digest` array of 32 raw binary bytes, not hexadecimal text

Remarks

TPLSHA256Digest is declared as Array [0..31] of Byte; the digest is produced first as a binary string and then copied into the typed array, and the same Keccak permutation serves SHA3_384ByteArray and SHA3_512ByteArray with different rates and output lengths

Example

Digest:= SHA3_256ByteArray(Data);
