				TPM Management - tpmtoken_protect

NAME
       tpmtoken_protect  - encrypt or decrypt data using a symmetric key stored in the user's TPM
       PKCS#11 data store

SYNOPSIS
       tpmtoken_protect [ OPTION ]

DESCRIPTION
       tpmtoken_protect will encrypt or decrypt data using a symmetric key that is stored in the
       user's data store.  The key used to protect the data is a 256-bit AES key stored as a
       private Secret Key PKCS#11 object.  The object has the PKCS#11 label attribute of 'User
       Data Protection Key'.  The key is generated by the TPM PKCS#11 implementation when it is
       needed the first time.  Since it is generated as a private object, it is protected by the
       TPM on the platform.

       This command requires the '-i' and '-o' command options to be specified.
