   How does OpenSSL_sign work?

   How to use OpenSSL_sign with Ed25519 key in PHP?

   • Note: to use openssl_sign with ed25519 key in PHP 8.4 (and probably later versions), you need to explicitly pass 0 as algorithm identifier. Omitting this parameter will not work (because this parameter defaults to SHA1), but for some reason there is currently no OPENSSL_ALGO_xxxxx constant for the default signature algorithm.
