ARIA for 128, 192 and 256 bit keys in CBC\-MAC Mode (CCM) and Galois Counter
Mode (GCM). These ciphers require additional control operations to function
correctly, see the "AEAD INTERFACE" in \fBEVP_EncryptInit\fR\|(3) section for details.
.SH NOTES
.IX Header "NOTES"
Developers should be aware of the negative performance implications of
calling these functions multiple times and should consider using
\&\fBEVP_CIPHER_fetch\fR\|(3) with \fBEVP_CIPHER\-ARIA\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.
