None of these algorithms are provided by the OpenSSL default provider.
To use them it is necessary to load either the OpenSSL legacy provider or another
implementation.

"NOTES"
Header "NOTES" Developers should be aware of the negative performance implications of
calling these functions multiple times and should consider using
\fBEVP_CIPHER_fetch\|(3) instead.
See \*(L"Performance\*(R" in crypto\|(7) for further information.
"RETURN VALUES"
Header "RETURN VALUES" These functions return an \s-1EVP_CIPHER\s0 structure that contains the
implementation of the symmetric cipher. See EVP_CIPHER_meth_new\|(3) for
details of the \s-1EVP_CIPHER\s0 structure.
