BSCRYPTO(8)

NAME
 bscrypto - Bareos's 'SCSI Crypto'

SYNOPSIS
bscrypto [options] device_name

DESCRIPTION

The purpose of bscrypto is to be a standalone tool for manipulating the SCSI Crypto framework using the SCSI SPIN/SPOUT security pages. This tool allows you to perform standalone crypto operations that are normally performed by the scsicrypto-sd.so plugin in the storage daemon.

You also need bscrypto tool to to the initial setup of things like Key Encryption Keys in the bareos-sd and bareos-dir configuration files.

OPTIONS
A summary of options is included below.

-?  Show version and usage of program.

-b  Perform base64 encoding of keydata. Any binary data is base64 encoded and as such converted to normal ASCII.

-c  Clear encryption key. Clear the encryption key currently loaded on the drive by issuing a SCSI SPOUT clear key page.

-D <cachefile>
    Dump the content of given cachefile

-d <nn>
    Set debug level to <nn>

-e  Show drive encryption status. Request the current drive encryption status by issuing a SCSI SPIN cmd requesting the SPIN_DATA_ENCR_STATUS_PAGE.

-g <keyfile>
    Generate new encryption passphrase in keyfile. A passphrase is generated from random data and is ASCII only.

-k <keyfile>
    Show content of keyfile. If the data is wrapped using a so called Key Encryption Key you also need the -b flag to base64 decode the data that is wrapped using the algorithm described in RFC3394 which gives binary output.

-p <cachefile>
    Populate given cachefile with crypto keys

-r <cachefile>
    Reset expiry time for entries of given cachefile

-s <keyfile>
    Set encryption key loaded from keyfile. Load the new key from the keyfile and load it into the drives crypto buffer using a SCSI SPOUT command.

-v  Show volume encryption status. Request the current volume encryption status by issuing a SCSI SPIN cmd requesting the SPIN_NEXT_BLOCK_ENCR_STATUS_PAGE.

-w <keyfile>
    Wrap/Unwrap the key using RFC3394 aes-(un)wrap using the key in keyfile as a Key Encryption Key After wrapping the data using this option the output is binary so you may want to use the -b flag to base64 encode this data.
