The B<DER> option uses an ASN.1 DER encoded -form compatible with RFC 3279 EcpkParameters. The PEM form is the default -format: it consists of the B<DER> format base64 encoded with additional -header and footer lines. - -=item B<-outform DER|PEM> - -This specifies the output format, the options have the same meaning as the -B<-inform> option. - -=item B<-in filename> - -This specifies the input filename to read parameters from or standard input if -this option is not specified. - -=item B<-out filename> - -This specifies the output filename parameters to. Standard output is used -if this option is not present. The output filename should B<not> be the same -as the input filename. - -=item B<-noout> - -This option inhibits the output of the encoded version of the parameters. - -=item B<-text> - -This option prints out the EC parameters in human readable form. - -=item B<-C> - -This option converts the EC parameters into C code. The parameters can then -be loaded by calling the B<get_ec_group_XXX()> function. - -=item B<-check> - -Validate the elliptic curve parameters. - -=item B<-name arg> - -Use the EC parameters with the specified 'short' name. Use B<-list_curves> -to get a list of all currently implemented EC parameters. - -=item B<-list_curves> - -If this options is specified B<ecparam> will print out a list of all -currently implemented EC parameters names and exit. - -=item B<-conv_form> - -This specifies how the points on the elliptic curve are converted -into octet strings. Possible values are: B<compressed> (the default -value), B<uncompressed> and B<hybrid>. For more information regarding -the point conversion forms please read the X9.62 standard. -B<Note> Due to patent issues the B<compressed> option is disabled -by default for binary curves and can be enabled by defining -the preprocessor macro B<OPENSSL_EC_BIN_PT_COMP> at compile time. - -=item B<-param_enc arg> - -This specifies how the elliptic curve parameters are encoded. -Possible value are: B<named_curve>, i.e. the ec parameters are -specified by a OID, or B<explicit> where the ec parameters are -explicitly given (see RFC 3279 for the definition of the -EC parameters structures). The default value is B<named_curve>. -B<Note> the B<implicitlyCA> alternative ,as specified in RFC 3279, -is currently not implemented in OpenSSL. - -=item B<-no_seed> - -This option inhibits that the 'seed' for the parameter generation -is included in the ECParameters structure (see RFC 3279). - -=item B<-genkey> - -This option will generate a EC private key using the specified parameters. - -=item B<-rand file(s)> - -a file or files containing random data used to seed the random number -generator, or an EGD socket (see L<RAND_egd(3)|RAND_egd(3)>). -Multiple files can be specified separated by a OS-dependent character. -The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for -all others. - -=item B<-engine id> - -specifying an engine (by its unique B<id> string) will cause B<ecparam> -to attempt to obtain a functional reference to the specified engine, -thus initialising it if needed. The engine will then be set as the default -for all available algorithms. - -=back - -=head1 NOTES - -PEM format EC parameters use the header and footer lines: - - -----BEGIN EC PARAMETERS----- - -----END EC PARAMETERS----- - -OpenSSL is currently not able to generate new groups and therefore -B<ecparam> can only create EC parameters from known (named) curves. - -=head1 EXAMPLES - -To create EC parameters with the group 'prime192v1': - - openssl ecparam -out ec_param.pem -name prime192v1 - -To create EC parameters with explicit parameters: - - openssl ecparam -out ec_param.pem -name prime192v1 -param_enc explicit - -To validate given EC parameters: - - openssl ecparam -in ec_param.pem -check - -To create EC parameters and a private key: - - openssl ecparam -out ec_key.pem -name prime192v1 -genkey - -To change the point encoding to 'compressed': - - openssl ecparam -in ec_in.pem -out ec_out.pem -conv_form compressed - -To print out the EC parameters to standard output: - - openssl ecparam -in ec_param.pem -noout -text - -=head1 SEE ALSO - -L<ec(1)|ec(1)>, L<dsaparam(1)|dsaparam(1)> - -=head1 HISTORY - -The ecparam command was first introduced in OpenSSL 0.9.8. - -=head1 AUTHOR - -Nils Larsch for the OpenSSL project (http://www.openssl.org) - -=cut |
