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.
