See \fBEC_GROUP_copy\fR\|(3) for a description of point_conversion_form. .PP When reading a private key encoded without an associated public key (e.g. if \&\s-1EC_PKEY_NO_PUBKEY\s0 has been used \- see below), then \fBd2i_ECPrivateKey()\fR generates the missing public key automatically. Private keys encoded without parameters (e.g. if \s-1EC_PKEY_NO_PARAMETERS\s0 has been used \- see below) cannot be loaded using \&\fBd2i_ECPrivateKey()\fR. .PP The functions \fBEC_KEY_get_enc_flags()\fR and \fBEC_KEY_set_enc_flags()\fR get and set the value of the encoding flags for the \fBkey\fR. There are two encoding flags currently defined \- \s-1EC_PKEY_NO_PARAMETERS\s0 and \s-1EC_PKEY_NO_PUBKEY.\s0 These flags define the behaviour of how the \fBkey\fR is converted into \s-1ASN1\s0 in a call to \&\fBi2d_ECPrivateKey()\fR. If \s-1EC_PKEY_NO_PARAMETERS\s0 is set then the public parameters for the curve are not encoded along with the private key. If \s-1EC_PKEY_NO_PUBKEY\s0 is set then the public key is not encoded along with the private key. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBEC_KEY_get_enc_flags()\fR returns the value of the current encoding flags for the \&\s-1EC_KEY.\s0 .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBcrypto\fR\|(7), \fBEC_GROUP_new\fR\|(3), \&\fBEC_GROUP_copy\fR\|(3), \fBEC_POINT_new\fR\|(3), \&\fBEC_POINT_add\fR\|(3), \&\fBEC_GFp_simple_method\fR\|(3), \&\fBd2i_ECPKParameters\fR\|(3), \&\fBd2i_ECPrivateKey\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2015\-2017 The OpenSSL Project Authors.
