+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+The \fBRSA\fR keytype and its parameters are described in \fBEVP_PKEY\-RSA\fR\|(7).
+See \fBEVP_PKEY_encapsulate\fR\|(3) and \fBEVP_PKEY_decapsulate\fR\|(3) for more info.

+The OpenSSL RSA Key Encapsulation Mechanism only currently supports the
+following default operation (operating mode):
+.RS 4
+.IP """RSASVE""" 4
+.IX Item """RSASVE"""
+The encapsulate function simply generates a secret using random bytes and then
+encrypts the secret using the RSA public key (with no padding).
+The decapsulate function recovers the secret using the RSA private key.
+.RE
+.RS 4
+.Sp
+This can be set using \fBEVP_PKEY_CTX_set_kem_op()\fR.

+.IX Header "HISTORY"
+This functionality was added in OpenSSL 3.0.

+The \f(CW\*(C`operation\*(C'\fR (operating mode) was a required parameter prior to OpenSSL 3.5.
+As of OpenSSL 3.5, \f(CW\*(C`RSASVE\*(C'\fR is the default operating mode, and no explicit
+value need be specified.
