SHA3_512ByteArray

Cryptography

Description

Computes the SHA3-512 digest of a byte array and returns it as a fixed-size TPLSHA512Digest value of 64 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 72-byte rate; an empty array returns the digest of the empty message

Syntax

Delphi

Function SHA3_512ByteArray(Input: Array Of Byte): TPLSHA512Digest;

Return values

	The SHA3-512 digest as a `TPLSHA512Digest` array of 64 raw binary bytes, not hexadecimal text

Remarks

TPLSHA512Digest is declared as Array [0..63] of Byte; the digest is produced first as a binary string and then copied into the typed array, and the rate shrinks to 72 bytes because the Keccak rate is 200 minus twice the output length

Example

Digest:= SHA3_512ByteArray(Data);
