NAME

    curve-keygen - a utility to generate CURVE25519 keypairs.

SYNOPSIS

     Usage: curve-genkey [options]

     Options:

      -f     Filename for the key, default: 'id_curve25519'.

      -n        Your name

      -m        Your email address

      -o         Your organization

      -y              Read private key file and print public key, requires -s

      -s  File containing a secret key

      -c              Don't encrypt the secret key (CZMQ default)

      -h              print this help message

      -v              print program version

DESCRIPTION

    curve-genkey generates a CURVE25519 keypair. It stores the public key in

    CZMQ's zcert format and the private key in binary form. If the option -c

    have been supplied or if no passphrase provided, the private key will be

    stored in zcert format as well.

LIBRARY

    A library libcsk is available which can be used from client programs to

    access encrypted private keys. Example usage:

     #include 

     #include 

 

     int main() {

       size_t rawsize;

       char secretfile[] = "id_curve25519_secret";

       char passphrase[] = "my password";

       unsigned char *raw = csk_raw_load(secretfile, &rawsize);

       zcert_t *cert = csk_zcert_decrypt(raw, passphrase, rawsize);

       if(cert != NULL) {

         // do something with cert

       }

       return 0;

     }

    Compile the client program with -lcsk ld flag.

FILES

    curve-keygen creates by default files in the current directory. If not

    further specified these are:

    id_curve25519_secret

        The encrypted private key in binary form. If the private key is

        saved without encryption this file will be in CZMQ zcert format.

    id_curve25519

        The public key in CZMQ zcert format.

BUGS

    Currently curve-keygen stores the encrypted private key as raw binary

    stream to disk. This is not portable. A future version will save the key

    in IETF format or - once CZMQ provides support for it - in

    zcert-secret-format (however that might be named then).
