% tpm2_testparms(1) tpm2-tools | General Commands Manual
# NAME
**tpm2_testparms**(1) - Verify that specified algorithm suite is supported by TPM
# SYNOPSIS
**tpm2_testparms** [*OPTIONS*] [*ARGUMENT*]
# DESCRIPTION
**tpm2_testparms**(1) - Checks that the suite specified by _ALG\_SPEC_ is
available for usage per _ALGORITHM_.
Algorithms should follow the "formatting standards", see section "Algorithm Specifiers".
Also, see section "Supported Signing Schemes" for a list of supported hash algorithms.
# OPTIONS
This tool accepts no tool specific options.

# EXAMPLES
## Check whether if "rsa" is supported
```bash
tpm2_testparms rsa
```
## Check that ECDSA using P-256 with AES-128 CTR mode is available
```bash
tpm2_testparms ecc256:ecdsa:aes128ctr
```
