.Sh DESCRIPTION
.Nm
can be used to create an ECC private key and to print the corresponding public key.
You must specify a filename containing an ECC private key in GNUnet format as an argument.
If the file does not exist, gnunet-ecc will create a key.
This may then take a while.
If the option
.Fl p
is given, the corresponding public key will be printed to the console.
.Bl -tag -width indent

Create COUNT public-private key pairs and write them to FILENAME.

.It Fl p | -print-public-key
Print the corresponding public key to stdout.
This is the value used for PKEY records in GNS.
.It Fl P | -print-private-key
Print the corresponding private key to stdout.
This is the value used for PKEY records in GNS.
