wp_verify_fast_hash() │ WP 6.8.0

Checks whether a plaintext message matches the hashed value. Used to verify values hashed via wp_fast_hash().

The function uses Sodium to hash the message and compare it to the hashed value. If the hash is not a generic hash, the hash is treated as a phpass portable hash in order to provide backward compatibility for passwords and security keys which were hashed using phpass prior to WordPress 6.8.0.

No Hooks.

Returns

true|false. Whether the message matches the hashed message.
