Per OpenSSL documentation [^1] and the usage of `LibCrypto#evp_cipher_flags`, `EVP_CIPHER_get_flags` should accept `EVP_CIPHER` rather than `EVP_CIPHER_CTX`. An example of this usage can be seen in `OpenSSL::Cipher#authenticated?`. This change does not introduce any functional impact but improves clarity by correctly reflecting the expected argument, reducing the need for developers to cross-check other sources.
