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