tarsnap-keygen — generate a key file for use with tarsnap(1)
|tarsnap-keygen|| --keyfile |
tarsnap-keygen generates cryptographic keys, registers with the tarsnap server, and writes a key file for use with tarsnap(1).
key-file option specifies the name of the file in which to write the newly-generated keys. The --user
user-name option specifies 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 encrypt 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 approximately
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.
