+Deprecated since OpenSSL 3.0, can be hidden entirely by defining
+B<OPENSSL_API_COMPAT> with a suitable version value, see
+L<openssl_user_macros(7)>:
+
EVP_CIPHER *EVP_CIPHER_meth_new(int cipher_type, int block_size, int key_len);
EVP_CIPHER *EVP_CIPHER_meth_dup(const EVP_CIPHER *cipher);
void EVP_CIPHER_meth_free(EVP_CIPHER *cipher);
=head1 DESCRIPTION
+All of the functions described on this page are deprecated.
+Applications should instead use the OSSL_PROVIDER APIs.
+
The B<EVP_CIPHER> type is a structure for symmetric cipher method
implementation.
=head1 HISTORY
+All of these functions were deprecated in OpenSSL 3.0.
+
The functions described here were added in OpenSSL 1.1.0.
The B<EVP_CIPHER> structure created with these functions became reference
counted in OpenSSL 3.0.
