\&\fBEVP_PKEY_set1_EC_KEY()\fR set the key referenced by \fBpkey\fR to \fBkey\fR.
.PP
\&\fBEVP_PKEY_get1_RSA()\fR, \fBEVP_PKEY_get1_DSA()\fR, \fBEVP_PKEY_get1_DH()\fR and
\&\fBEVP_PKEY_get1_EC_KEY()\fR return the referenced key in \fBpkey\fR or

\&\fBEVP_PKEY_assign_RSA()\fR, \fBEVP_PKEY_assign_DSA()\fR, \fBEVP_PKEY_assign_DH()\fR
and \fBEVP_PKEY_assign_EC_KEY()\fR also set the referenced key to \fBkey\fR
however these use the supplied \fBkey\fR internally and so \fBkey\fR
will be freed when the parent \fBpkey\fR is freed.
.PP
\&\fBEVP_PKEY_type()\fR returns the type of key corresponding to the value
\&\fBtype\fR. The type of a key can be obtained with
EVP_PKEY_type(pkey\->type). The return value will be \s-1EVP_PKEY_RSA,
EVP_PKEY_DSA, EVP_PKEY_DH\s0 or \s-1EVP_PKEY_EC\s0 for the corresponding
key types or NID_undef if the key type is unassigned.
.SH "NOTES"
.IX Header "NOTES"
In accordance with the OpenSSL naming convention the key obtained
from or assigned to the \fBpkey\fR using the \fB1\fR functions must be
freed as well as \fBpkey\fR.
