DESCRIPTION

17       The TPMLIB_GetInfo() function allows to query for TPM implementation
18       specifics and get a JSON string in return. Which data is to be returned
19       can be specified in the flags parameter that may be a logical 'or'
20       concatenation of flags. If passed flags are not supported, nothing is
21       returned . If a 0 is passed in, an empty JSON Object '{}' is returned.
22
23       The following flags are defined and return JSON objects as shown:

26           {"TPMSpecification":{"family":"1.2","level":2,"revision":116}}
27
28       TPMLIB_INFO_TPMATTRIBUTES
29           {"TPMAttributes":{"manufacturer":"id:00001014","version":"id:00740001","model":"swtpm"}}
30
31       TPMLIB_INFO_TPMFEATURES (since v0.8.0)
32           {"TPMFeatures":{"RSAKeySizes":[1024,2048,3072]}}

34           This JSON object may be extended in the future.
