Permission Description ACCESS_xxx_xxx ACCESS_xxx_Rxx ACCESS_Rxx_xxx ACCESS_xxx_RW x ACCESS_Rxx_RWD ACCESS_RWD_xxx ACCESS_INT_xxx_Rxx ACCESS_INT_Rxx_RWx No access from anywhere in any state. This is used for placeholder attributes that represent functionality that will be added at a later date. Read-only access in the low state no access in the high state. This is used for status information when the object is in the low state that no longer has any meaning once it has been moved into the high state for example the details of a key that is required in order to move the object into the high state. Read-only access in the high state no access in the low state. This is used for information that is created when the object changes states for example a certificate fingerprint hash of the encoded certificate that only exists once the certificate has been signed and is in the high state. Read write access in the low state no access in the high state. This is a variant of ACCESS_xxx_Rxx and is used for information that has no meaning in the high state but is required in the low state. Full access in the low state read-only access in the high state. This is used for information that can be manipulated freely in the low state but that becomes immutable once the object has been moved into the high state typical examples being certificate attributes. Full access in the high state no access in the low state. This is used for information pertaining to fully initialised objects for example signed certificates that doesn t apply when the object is in the low state where the details of the object are still subject to change. Internal read-only access in the low state no external access or access in the high state. This is identical to ACCESS_xxx_Rxx except that it is used for attributes that are only visible internally. Internal read write access in the low state internal read-only access in the high
