Hi all,
I'm looking for secure file encryption tools that use MAC address as encryption key. FYI, I'm using Red Hat Enterprise Linux OS.
For example: when A wants to send file to B
A will encrypt the file with B's computer MAC/IP address as an encryption key
This file can only be decrypted... (2 Replies)
My dilemma,
I need to send, deemed confidential, information via e-mail (SMTP). This information is sitting as a file on AIX. Typically I can send this data as a e-mail attachment via what we term a "mail filter" using telnet. I now would like to somehow encrypt the data and send it to a e-mail... (1 Reply)

TCG Software Stack Developer's Reference
NAME
Tspi_TPM_CMKSetRestrictions - set restrictions on use of delegated Certified Migratable Keys
SYNOPSIS
#include <tss/tspi.h>
TSS_RESULT Tspi_TPM_CMKSetRestrictions(TSS_HTPM hTPM, TSS_CMK_DELEGATE CmkDelegate);
DESCRIPTION
Tspi_TPM_CMKSetRestrictions is used to set restrictions on the delegated use of Certified Migratable Keys (CMKs). Use of this command can-
not itself be delegated.
PARAMETERS
hTPM
The hTPM parameter is used to specify the handle of the TPM object.
CmkDelegate
The CmkDelegate parameter is a bitmask describing the kinds of CMKs that can be used in a delegated auth session. Each bit represents a
type of key. If the bit of a key type is set, then the CMK can be used in a delegated authorization session, otherwise use of that key
will result in a TPM_E_INVALID_KEYUSAGE return code from the TPM.
The possible values of CmkDelegate are any combination of the following flags logically OR'd together:
TSS_CMK_DELEGATE_SIGNING
Allow use of signing keys.
TSS_CMK_DELEGATE_STORAGE
Allow use of storage keys.
TSS_CMK_DELEGATE_BIND
Allow use of binding keys.
TSS_CMK_DELEGATE_LEGACY
Allow use of legacy keys.
TSS_CMK_DELEGATE_MIGRATE
Allow use of migratable keys.
RETURN CODES
Tspi_TPM_CMKSetRestrictions returns TSS_SUCCESS on success, otherwise one of the following values is returned:
TSS_E_INVALID_HANDLE
hTPM is not a valid handle.
TSS_E_INTERNAL_ERROR
An internal SW error has been detected.
CONFORMING TO
Tspi_TPM_CMKSetRestrictions conforms to the Trusted Computing Group Software Specification version 1.2 Errata A
