To use it is necessary to load either the OpenSSL legacy provider or another implementation. .PP Developers should be aware of the negative performance implications of calling this function multiple times and should consider using \&\fBEVP_CIPHER_fetch\fR\|(3) with \fBEVP_CIPHER\-DES\fR\|(7) instead. See "Performance" in \fBcrypto\fR\|(7) for further information. .SH "RETURN VALUES" .IX Header "RETURN VALUES" These functions return an \fBEVP_CIPHER\fR structure that contains the implementation of the symmetric cipher. See \fBEVP_CIPHER_meth_new\fR\|(3) for details of the \fBEVP_CIPHER\fR structure. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBevp\fR\|(7), \&\fBEVP_EncryptInit\fR\|(3), \&\fBEVP_CIPHER_meth_new\fR\|(3) .SH COPYRIGHT .IX Header "COPYRIGHT" Copyright 2017\-2023 The OpenSSL Project Authors.
