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

Synopsis

–-keyfile key-file –-user user-name –-machine machine-name [--passphrased ] [--passphrase-mem maxmem ]

Description

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

The –-keyfile –-user and –-machine parameters are all required.

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.
