tpmnv_defindex is used to define an index in TPM NV
storage. You can use this to store data in the TPM so that it can be only
accessed when certain conditions are met.
- -i index
- NV index to use. You can specify an integer or use the following symbolic
names: default (0x50000001), owner (0x40000001) or aux (0x50000002).
- -s size
- Size of the NV storage in bytes.
- -pv permission_value
- Permission value to use for the storage. This is mandatory unless you
specify an index that has a default value: default (0x00002000), owner
(0x00000002) or aux (0x00000000).
- -p password
- Owner password for the index.
- -av authentication_value
- Authentication value for the index. Used as a password with
AUTHREAD/AUTHWRITE.
- -wl write_locality
- Write locality value. There are 5 localities: 0-4. For example the
locality value is 0x18 if you want to allow localities 3 or 4.
- -rl read_locality
- Read locality value. There are 5 localities: 0-4. For example the locality
value is 0x18 if you want to allow localities 3 or 4.
- -h
- Print the help text.
