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

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.
