TARSNAP-KEYGEN(1)	    General Commands Manual	     TARSNAP-KEYGEN(1)

NAME
       tarsnap-keygen -- generate a key	file for use with tarsnap(1)

SYNOPSIS
       tarsnap-keygen	 --keyfile   key-file	--user	 user-name   --machine
		      machine-name [--passphrased]  [--passphrase-mem  maxmem]
		      [--passphrase-time maxtime]
       tarsnap-keygen --version

DESCRIPTION
       tarsnap-keygen generates	cryptographic keys, registers with the tarsnap
       server, and writes a key	file for use with tarsnap(1).

       The  --keyfile  key-file	option specifies the name of the file in which
       to write	the newly-generated keys.  The --user user-name	option	speci-
       fies  the  name	(i.e.  email  address)	of  the	 Tarsnap account.  The
       --machine machine-name option specifies a name which will be  displayed
       in accounting reports so	that you can see how much data each machine is
       storing.

       If  the --passphrased option is specified, the user will	be prompted to
       enter a passphrase (twice) to be	used to	encrypt	the key	file.

       If the --passphrase-mem maxmem option is	specified, a maximum of	maxmem
       bytes of	RAM will be used in the	scrypt key derivation function to  en-
       crypt  the  key	file;  it may be necessary to set this option if a key
       file is being generated on a system with	far more RAM than  the	system
       on which	the key	file will be used.

       If  the --passphrase-time maxtime option	is specified, a	maximum	of ap-
       proximately maxtime seconds will	be used	in the scrypt  key  derivation
       function	to encrypt the key file.

       The  --version option prints the	version	number of tarsnap-keygen, then
       exits.
