There are some environment variables that it's useful to set to avoid repeating arguments to the tpm2-tools commands. options: fix TCTI handling to avoid failures for commands that should work with no options. % tpm2_readpublic (1) tpm2-tools | General Commands Manual NAME tpm2_readpublic (1) - Read the public area of a loaded object. This can be done by specifying the private as well as the public section or via a pem file using the -r option Trusted Platform Module (TPM) is an international standard for a secure cryptoprocessor, which is a dedicated microprocessor designed to secure hardware by integrating cryptographic keys into devices. An example to call it with a property value of 2 is: tpm2_getcap vendor:2 NOTE: if vendor requests hang, try the "-i" option to ignore the moreData field and only read once. When signing a message, tpm2_sign utility first calculates the digest of the message similar to the tpm2_hash command. After installation, the different tpm2 commands of tpm2-tools are available. The default is to start a trial session unless the -a option is specified. Options -c, --object-context = OBJECT: Context object for the object to read. tpm2_nvwrite (1) - Write data specified via FILE to a Non-Volatile (NV) index. For the Ubuntu Server 22. tpm2_nvread (1) - Read the data stored in a Non-Volatile (NV)s index. No TPM-specific API calls are needed: the applications may be completely unaware that the keys being used are stored within TPM. It is important to note that individual tools with prefix tpm2_ can still be invoked, however, they are now soft-linked to this tpm2 executable. Synopsis tpm2_shutdown [Options] Description tpm2_shutdown (1) - Send a TPM2_Shutdown command with either TPM_SU_CLEAR or TPM_SU_STATE. The command will create and load a Primary Object. SYNOPSIS tpm2_createek [OPTIONS] DESCRIPTION tpm2_createek (1) - Generate TCG profile compliant endorsement key (EK), which is the primary object of the endorsement hierarchy. Synopsis tpm2_getcap [Options] [CAPABILITY] Description tpm2_getcap (1) - Query the TPM for it’s capabilities / properties and print them to the console. The command is read from a file as a binary stream and transmitted to the TPM using the TCTI specified by the caller. Install tpm2-tools. Instructions for building and installing the tpm2-tools are provided in the INSTALL. SYNOPSIS tpm2_getekcertificate [OPTIONS] [ARGUMENT] DESCRIPTION tpm2_getekcertificate (1) - Retrieve the endorsement key certificate. 0 or how to enable TPM 2. Synopsis tpm2_policyauthorize [Options] Description tpm2_policyauthorize (1) - This command allows for policies to change by associating the policy to a signing authority and allowing the policy contents to change. 0 chips built into a wide range of todays devices. tpm2-tools This is not part of the TPM2 Software Stack per se, but is an end-user command line tool that can be used to generate keys, view capabilities, sign, hash, unseal, etc. Such an object intended for sealing data has to be of the type TPM_ALG_KEYEDHASH. 2-rc0 2021-09-01 tpm2_nvextend: Added option -n, --name to specify the name of the nvindex in hex bytes. The key context is analogous to the context file produced by tpm2_load (1), however is generated via a tpm2_createloaded (1) command. It can be specified as raw handle or an offset value to the nv handle range "TPM2_HR_NV_INDEX". Analogous to strerror (3), but for the TPM2 stack. --disable tpm2_clearcontrol (1) - Allows user with knowledge of either lockout auth and or platform hierarchy auth to set disableClear which prevents the lockout authorization's capability to execute tpm2_clear. It takes a string form of the capability to query as an argument to the tool. TPM is naturally supported only on devices that have TPM TCTI Configuration The TCTI or "Transmission Interface" is the communication mechanism with the TPM. The index can be specified as raw handle or an offset value to the nv handle range “TPM2_HR_NV_INDEX”. ARGUMENT the command line argument specifies the error code to be parsed. SYNOPSIS tpm2_startauthsession [OPTIONS] DESCRIPTION tpm2_startauthsession (1) - Starts a session with the TPM. tpm2_certify (1) - Proves that an object with a specific NAME is loaded in the TPM. Options -c, --key-context = OBJECT: Context object for the quote signing key. If you don't have a TPM 2. This is a thin wrapper around the GetCapability command. Values: TPM2_PT_VENDOR_STRING_1 and TPM2_PT_VENDOR_STRING_2 refers to the model/family of the TPM. The PCR bank to be used per PCR is defined in the cryptographic profile (cf. If a test fails, the TPM will return TPM_RC_FAILURE for any command other than TPM2_GetTestResult () and TPM2_GetCapability () during this time. tpm2_import (1) - Imports an external generated key as TPM managed key object. Configure/ modify the session attributes. Likely the caller % tpm2_nvread (1) tpm2-tools | General Commands Manual NAME tpm2_nvread (1) - Read the data stored in a Non-Volatile (NV)s index. Note: The command line option always overrides the environment variable. The options and arguments that follow are either the common options or those specific to the tool name. tpm2_load (1) - Load both the private and public portions of an object into the TPM or load the object in the TSS2-Private-Key PEM format. OPTIONS -l, --list: List known supported capability names. EXAMPLES tpm2_rc_decode 0x1d5 tpm:parameter(1):structure is the wrong size returns footer NAME ¶ tpm2 (1) - A single small executable that combines the various tpm2-tools much like a BusyBox that provides a fairly complete environment for any small or embedded system. 0 software simulator daemon. Algorithms should follow the "formatting standards", see section "Algorithm Specifiers % tpm2_encryptdecrypt (1) tpm2-tools | General Commands Manual NAME tpm2_encryptdecrypt (1) - Performs symmetric encryption or decryption. References common options collection of common options that provide information many users may expect. The response received from the TPM is written to the output file. A file path containing a TPM object or a TSS2 Private Key in the PEM format may be specified as the path argument. EXAMPLES Send a TPM Shutdown Command with flags TPM2_SU_STATE tpm2_shutdown Send a TPM Shutdown Command with flags TPM2_SU_CLEAR tpm2_shutdown -c NOTES Typically a Resource Manager (like tpm2-abrmd) or low-level/boot software will have already sent this command. tpm2_createprimary (1) - This command is used to create a primary object under one of the hierarchies: Owner, Platform, Endorsement, NULL. The command is read from stdin as a binary stream and transmitted to the TPM using the TCTI specified by the caller. What is tpm2-tools tpm2-tools is: This package contains a set of tools to use with TPM 2. Set % tpm2_clear (1) tpm2-tools | General Commands Manual NAME tpm2_clear (1) - Clears lockout, endorsement and owner hierarchy authorization values. OPTIONS -c, --key-context = OBJECT: Context object for the quote signing key. Package tpm2-tools A bunch of TPM testing toolS build upon tpm2-tss https://github. Options -c, --clear: Shutdown type sent will be TPM_SU_CLEAR instead of TPM2_SU_STATE. tpm2_send - Man Page Send a raw command buffer to the TPM. Changelog 5. If an index isn’t specified, the tool uses the first free index. As an argument takes the auth value for either platform or lockout hierarchy. moslqkenpxcnshejykvczenyzwiodvdlhsjuldkvpcasqei
