Synopsis

tpm2_createpolicy [Options]

Description

tpm2_createpolicy(1) - Creates simple assertion authorization policies based on multiple pcr indices values across multiple enabled banks. It can then be used with object creation and or tools using the object.

Options

These options control creating the policy authorization session:

Common Options

This collection of options are common to many programs and provide information that many users may expect.

This collection of environment variables that may be used to configure the various TCTI modules available.

The values passed through these variables can be overridden on a per-command basis using the available command line options, see the TCTI_OPTIONS section.

The variables respected depend on how the software was configured.

Tcti Options

This collection of options are used to configure the varous TCTI modules available. They override any environment variables.

Supported Hash Algorithms

Supported hash algorithms are:

NOTE: Your TPM may not support all algorithms.

Algorithm Specfiers

Options that take algorithms support "nice-names". Nice names, like sha1 can be used in place of the raw hex for sha1: 0x4. The nice names are converted by stripping the leading TPM_ALG_ from the Algorithm Name field and converting it to lower case. For instance TPM_ALG_SHA3_256 becomes sha3_256.

The algorithms can be found at: <https://trustedcomputinggroup.org/wp-content/uploads/TCG_Algorithm_Registry_Rev_1.24.pdf>

Examples

Create a authorization policy tied to a specific PCR index:

tpm2_createpolicy -P -L 0x4:0 -f policy.file -F pcr0.bin

Returns

0 on success or 1 on failure.
