Message:

Security: Explicitly require the hash PHP extension and add requirement checks during installation and upgrade.

This extension provides the hash() function and support for the SHA-256 algorithm, both of which are required for upcoming security related changes. This extension is almost universally enabled, however it is technically possible to disable it on PHP 7.2 and 7.3, hence the introduction of this requirement and the corresponding requirement checks prior to installing or upgrading WordPress.
