Feature: #102761 - Introduce class to generate/validate HMAC hashes 

See forge#102761

Description 

A new class \TYPO3\CMS\Core\Crypto\HashService has been introduced to enhance the security and flexibility in generating Hash-based Message Authentication Codes (HMACs). This class combines the functionality of GeneralUtility::hmac() and Extbase's HashService, while enforcing the use of an additional, mandatory secret for HMAC generation and HMAC string validation.

Impact 

Using the new class \TYPO3\CMS\Core\Crypto\HashService , it is now possible to mitigate the risk of HMAC reuse in unauthorized scenarios for the same input.
