+.SH NAME
+EVP_PKEY_todata, EVP_PKEY_export
+\&\- functions to return keys as an array of key parameters
+.SH SYNOPSIS
+.IX Header "SYNOPSIS"
+.Vb 1
+\& #include <openssl/evp.h>
+\&
+\& int EVP_PKEY_todata(const EVP_PKEY *pkey, int selection, OSSL_PARAM **params);
+\& int EVP_PKEY_export(const EVP_PKEY *pkey, int selection,
+\& OSSL_CALLBACK *export_cb, void *export_cbarg);

+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+The functions described here are used to extract \fBEVP_PKEY\fR key values as an
+array of \fBOSSL_PARAM\fR\|(3).
+.PP
+\&\fBEVP_PKEY_todata()\fR extracts values from a key \fIpkey\fR using the \fIselection\fR.
+\&\fIselection\fR is described in "Selections" in \fBEVP_PKEY_fromdata\fR\|(3).
+\&\fBOSSL_PARAM_free\fR\|(3) should be used to free the returned parameters in
+\&\fI*params\fR.
+.PP
+\&\fBEVP_PKEY_export()\fR is similar to \fBEVP_PKEY_todata()\fR but uses a callback
+\&\fIexport_cb\fR that gets passed the value of \fIexport_cbarg\fR.
+See \fBopenssl\-core.h\fR\|(7) for more information about the callback. Note that the
+\&\fBOSSL_PARAM\fR\|(3) array that is passed to the callback is not persistent after the
+callback returns. The user must preserve the items of interest, or use
+\&\fBEVP_PKEY_todata()\fR if persistence is required.
+.SH NOTES
+.IX Header "NOTES"
+These functions only work with key management methods coming from a provider.
+This is the mirror function to \fBEVP_PKEY_fromdata\fR\|(3).
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBEVP_PKEY_todata()\fR and \fBEVP_PKEY_export()\fR return 1 for success and 0 for failure.

+These functions were added in OpenSSL 3.0.

+Support for \fBML\-DSA\fR, \fBML\-KEM\fR and \fBSLH\-DSA\fR was added in OpenSSL 3.5.
