OTFE
From Free net encyclopedia
On-the-fly encryption (OTFE) is a term often used when referring to disk encryption software. "On-the-fly" refers to the fact that the files are accessible immediately after providing the key, and the entire volume is typically mounted as if it were a physical drive, making the files just as accessible as any unencrypted ones.
On-the-fly encryption requires the use of device drivers enabling the encryption process to be transparent to the end user. Typical advantages of OTFE are that encryption takes place without user intervention, and that a single password encrypts almost unlimited data. Disadvantages are that poorly written implementations may have lots of overhead, and a crash in OTFE software may lead to data loss.
