Encrypting abstracts afore it is stored on the average may abate apropos about abstracts remanence. If the decryption key is able and anxiously controlled (i.e., not itself accountable to abstracts remanence), it may finer accomplish any abstracts on the average unrecoverable. Even if the key is stored on the medium, it may prove easier or quicker to overwrite just the key, vs the absolute disk.
Encryption may be done on a file-by-file basis, or on the accomplished disk. Cold cossack attacks are one of the few accessible methods for abolition a full-disk encryption method, as there is no achievability of autumn the apparent argument key in an unencrypted area of the medium. See the area Complications: Abstracts in RAM for added discussion.
Other side-channel attacks, like the use of hardware-based keyloggers or accretion of a accounting agenda absolute the decryption key, may action a greater adventitious to success, but do not await on weaknesses in the cryptographic adjustment employed. As such, their appliance for this commodity is minor.
