Re: Encryption as a accepted mean of sanitization

Hi Connie,

I completely understand this. However my question was about NIST.

Does NIST now recognize one-way encryption of the HDD as a possible
mean to destruct the Data???

Sanitization ensures the data is *gone*. Encryption simply ensures that
the data is inaccessible until such a time that it can be cracked (could
be 2 years, could be 20 years) - but the data is still there - and
potentially crackable.

The reason I ask this question is because there is a debate going on @
Wikipedia on this topic between user:maxt and user:tngr (don't know who
they are).

See:
1) http://en.wikipedia.org/wiki/Talk:Full_disk_encryption ; and
2) http://en.wikipedia.org/wiki/FDE

IT would be nice to have some clarity on this topic.
