TIdHash128.HashValue Method (string)

Implements calculation of a hash value for input data.

Pascal

function HashValue(
    const ASrc: string
): T4x4LongWordRecord; overload;

Parameters

Parameters	Description
ASrc	String containing data used to calculate the hash value.

Returns

T4x4LongWordRecord - 128-bit hash value for the input data.

Description

HashValue is an overloaded T4x4LongWordRecord function in TIdHash128 that specifies the mechanism used to calculate the 128-bit hash value for the input data.

The string-based variant of HashValue creates a TIdStream instance used to calculate the hash value, and calls the overloaded HashValue method.

The stream-based variant of HashValue is an abstract virtual function that must be reimplemented in a descendant class, like TIdHashMessageDigest, to support the specifics of the hashing algorithm.
