where options are
-inform arg input format - default PEM (DER or PEM)
-outform arg output format - default PEM
-in arg input file - default stdin
-out arg output file - default stdout
-noout do not print the ec parameter
-text print the ec parameters in text form
-check validate the ec parameters
-C print a 'C' function creating the parameters
-name arg use the ec parameters with 'short name' name
-list_curves prints a list of all currently available curve 'short names'
-conv_form arg specifies the point conversion form
possible values: compressed
uncompressed (default)
hybrid
-param_enc arg specifies the way the ec parameters are encoded
in the asn1 der encoding
possible values: named_curve (default)
explicit
-no_seed if 'explicit' parameters are choosen do not use the seed
-genkey generate ec key
-rand file files to use for random number input
-engine e use engine e, possibly a hardware device
