"Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the

      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,

      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

(a) You must give any other recipients of the Work or

(b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

(c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

(d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed

      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with

      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

NAME
----
snphost - Command line tool for managing the AMD SEV-SNP environment.

SYNOPSIS
--------
*snphost* [GLOBAL_OPTIONS] [_COMMAND_] [_COMMAND_ARGS_] +
*snphost* [_-h, --help_] +
*snphost* *command* *--help*

DESCRIPTION
-----------
snphost is a CLI utility for managing and interacting with the AMD SEV-SNP
firmware device of a host system.

GLOBAL OPTIONS
--------------
*-q, --quiet*:: Don't print any output to the console.

COMMANDS
--------
*snphost export*::
        usage: snphost export [der, pem] DIR-PATH

This command exports the SEV-SNP certificate chain to the directory
        provided by DIR-PATH. User must specify if the certificates currently
        stored on the PSP are encoded in DER or PEM format. These are the only
        two encoding formats supported in this tool.

options:
        -h, --help      Show a help message.

*snphost import*::
	usage: snphost import DIR-PATH

This command imports serialized SEV-SNP certificates to the host's PSP.
        Currently, only the ASK, ARK, and VCEK are able to be imported to the
        PSP. Note that there are a few user requirements for this command to
        work as intended.

All certificates must be located in the same directory with specific
        names:
                ARK certificate => ark.{pem, der}
                ASK certificate => ask.{pem, der}
                VCEK certificate => vcek.{pem, der}

Not all certificates are needed in the directory, only the ones that a
        user is looking to import to the PSP.

options:
        -h, --help      Show a help message

*snphost ok*::
	usage: snphost ok

This command probes the processor, sysfs, and KVM for AMD SEV-SNP
        related capabilities on the host and emits the results.

options:
    -h, --help          Show a help message

*snphost reset*::
	usage: snphost reset

This command resets the SEV-SNP platform. This will clear all
        persistent data managed by the platform.

options:
        -h, --help      Show a help message.

*snphost show*::
        usage: snphost show [guests, identifier, tcb, vcek-url, version ]

This command describes the state of the SEV-SNP platform. There are
        several platform details to describe:

Guest count:            snphost show guests
        Platform identifier:    snphost show identifier
        TCB version:            snphost show tcb
        VCEK URL:               snphost show vcek-url
        Firmware version:       snphost show version

options:
    -h, --help          Show a help message

*snphost verify*::
	usage: snphost verify ARK-PATH ASK-PATH VCEK-PATH

This command verifies the full SEV-SNP/CA certificate chain.
        Certificates must be encoded in PEM format.

options:
    -h, --help          Show a help message

*snphost fetch ca*::
	usage: snphost fetch ca [ der, pem ] DIR-PATH

This command fetches the host system's CA certificate chain and writes
        the encoded certificates to the directory at path DIR-PATH. Users must
        specify which format they would like the certificate to be encoded
        in (DER or PEM).

options:
    -h, --help          Show a help message

*snphost fetch vcek*::
	usage: snphost fetch vcek [ der, pem ] DIR-PATH

This command fetches the host system's versioned chip endorsement
        key (VCEK) and writes the encoded certificate to the directory at path
        DIR-PATH. Users must specify which format they would like the
        certificate to be encoded in (DER or PEM).

options:
    -h, --help          Show a help message

*snphost fetch crl*::
	usage: snphost fetch crl DIR-PATH

This command fetches the host system's certificate revokation list
        (CRL) and writes the encoded list to the directory at path DIR-PATH.

options:
    -h, --help          Show a help message
