.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBEVP_PKEY_CTX_get0_pkey()\fR is used to access the \fB\s-1EVP_PKEY\s0\fR
associated with the given \fB\s-1EVP_PKEY_CTX\s0\fR \fIctx\fR.
The \fB\s-1EVP_PKEY\s0\fR obtained is the one used for creating the \fB\s-1EVP_PKEY_CTX\s0\fR
using either \fBEVP_PKEY_CTX_new\fR\|(3) or \fBEVP_PKEY_CTX_new_from_pkey\fR\|(3).
.PP
\&\fBEVP_PKEY_CTX_get0_peerkey()\fR is used to access the peer \fB\s-1EVP_PKEY\s0\fR
associated with the given \fB\s-1EVP_PKEY_CTX\s0\fR \fIctx\fR.
The peer \fB\s-1EVP_PKEY\s0\fR obtained is the one set using
either \fBEVP_PKEY_derive_set_peer\fR\|(3) or \fBEVP_PKEY_derive_set_peer_ex\fR\|(3).
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBEVP_PKEY_CTX_get0_pkey()\fR returns the \fB\s-1EVP_PKEY\s0\fR associated with the
\&\s-1EVP_PKEY_CTX\s0 or \s-1NULL\s0 if it is not set.
.PP
\&\fBEVP_PKEY_CTX_get0_peerkey()\fR returns the peer \fB\s-1EVP_PKEY\s0\fR associated with the
\&\s-1EVP_PKEY_CTX\s0 or \s-1NULL\s0 if it is not set.
.PP
The returned \s-1EVP_PKEY\s0 objects are owned by the \s-1EVP_PKEY_CTX,\s0
and therefore should not explicitly be freed by the caller.
.PP
These functions do not affect the \s-1EVP_PKEY\s0 reference count.
They merely act as getter functions, and should be treated as such.
