Function SHA256Hash

Previous pageReturn to chapter overviewNext page   

Calculates SHA-2/SHA-256 hash.

 

Unit

EHash

 

Syntax

 

Code (Delphi)

function SHA256Hash(

const AData: Pointer;

const ADataSize: Cardinal

): TSHA256Hash; overload;

 

function SHA256Hash(

const AData: RawByteString

): TSHA256Hash; overload;

 

Parameters

AData [in]

A data to calculate hash.

 

ADataSize [in]

Size of AData in bytes.

 

Return value

SHA-256 hash of the specified AData.

 

Remarks

SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions. The SHA-2 family consists of six hash functions with digests (hash values) that are 224, 256, 384 or 512 bits: SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256. SHA-256 and SHA-512 are novel hash functions computed with 32-bit and 64-bit words, respectively. They use different shift amounts and additive constants, but their structures are otherwise virtually identical, differing only in the number of rounds.

 

The SHA-2 hash function is implemented in some widely used security applications and protocols, including TLS and SSL, PGP, SSH, S/MIME, and IPsec.

 

Important!

SHA-2 is considered to be more secure than SHA-1.
