Description

Calculate a binary hash value giving a text

Syntax

s = SHA256(sTextToHash [, ReturnType])

Returns

String

Parameters

Name

Type

Optional

Meaning

sTextToHash

String

Text message to be hashed

ReturnType

String

Yes

Optional value indicating the kind of return value.

If nothing is indicated, SHA256 binary string will be returned

Otherwise use one of the following value:

%SHA256_Bin	will return binary string
%SHA256_HexL	will return HEX lower string
%SHA256_HexU	will return HEX UPPER string
%SHA256_Base64	will return Base64 encoded string of the binary data

Hex conversion will convert considering binary string as a sequence of 8 single DWORD chunks: 32 bits x 8 DWORD = 256 bits
