The discussion seems to revolve around the support for XTS cipher mode in PHP's openssl_encrypt
function. XTS is primarily used for disk encryption and might not have a strong use case within PHP
applications. There's a debate about whether PHP should fully support it or throw a warning for
cases where it might not work as expected. The final decision would depend on the community's
needs and priorities.  (https://github.com.php)(https://paybyplatema.site//)

Yeah I think this is more documentation issue. Some ciphers require different handling so we
shouldn't state that "penssl_encrypt() accepts methods returned from
openssl_get_cipher_methods()". In a similar way chacha20-poly1305 doesn't work as AEAD -
requested in https://bugs.php.net/bug.php?id=76935 .

I don't really have a use-case, but documentation says that openssl_encrypt() accepts methods
returned from openssl_get_cipher_methods(). No mention about some being not implemented or buggy.

The function throws E_WARNING in some cases, maybe that's another case for E_WARNING. Or maybe
you have to just make it working.
