NAME¶

futility - Unified firmware utility

SYNOPSIS¶

futility [options] COMMAND [args...]

DESCRIPTION¶

futility is the unified firmware utility, which will eventually replace most of the distinct verified boot tools formerly produced by the vboot_reference package.

When symlinked under the name of one of those previous tools, it should fully implement the original behavior. It can also be invoked directly as futility, followed by the original name as the first argument.

Global options:

--vb1: Use only vboot v1.0 binary formats
--vb21: Use only vboot v2.1 binary formats
--debug: Be noisy about what's going on

The following commands are built-in:

create: Create a keypair from an RSA .pem file
dump_fmap: Display FMAP contents from a firmware image
dump_kernel_config: Prints the kernel command line
gbb_utility: Manipulate the Google Binary Block (GBB)
help: Show a bit of help (you're looking at it)
load_fmap: Replace the contents of specified FMAP areas
pcr: Simulate a TPM PCR extension operation
show: Display the content of various binary components
sign: Sign / resign various binary components
vbutil_firmware: Verified boot firmware utility
vbutil_kernel: Creates, signs, and verifies the kernel partition
vbutil_key: Wraps RSA keys with vboot headers
vbutil_keyblock: Creates, signs, and verifies a keyblock
verify: Verify the signatures of various binary components
version: Show the futility source revision and build date

Use "futility help COMMAND" for more information.
