For more information regarding +the point conversion forms please read the X9.62 standard. +\&\fBNote\fR Due to patent issues the \fBcompressed\fR option is disabled +by default for binary curves and can be enabled by defining +the preprocessor macro \fB\s-1OPENSSL_EC_BIN_PT_COMP\s0\fR at compile time. +.IP "\fB\-param_enc arg\fR" 4 +.IX Item "-param_enc arg" +This specifies how the elliptic curve parameters are encoded. +Possible value are: \fBnamed_curve\fR, i.e. the ec parameters are +specified by a \s-1OID,\s0 or \fBexplicit\fR where the ec parameters are +explicitly given (see \s-1RFC 3279\s0 for the definition of the +\&\s-1EC\s0 parameters structures).
