Predicate Ciphers::isOpenSslCipher

Holds if name is a known OpenSSL::Cipher. Supported ciphers depend on the version of OpenSSL or LibreSSL specified when installing the openssl gem. Ciphers listed here are sourced from OpenSSL 1.1.1 and LibreSSL 3.4.1.

In the general case, a name will include the cipher name, the key length, and the block encryption mode.

Note that since the cipher name itself always comes first in these names and always uses a “-” to demark to block mode, we can safely uppercase these names when checking against an algorithmRegex.
