¶ Wiping Algorithms with which WIPERAPP complies
TIP!
This is unique in WIPERAPP that when selecting the AUTO method, the application checks all available data wiping methods in the disk firmware and selects according to priority:
- Crypto Scramble Erase
- Block Erase
- Security Enhanced Erase
- Overwrite
The WIPERAPP software is fully compliant with the Purge and Clear standards described in the NIST 800-88 rev.1 (December 2014) document, which is the newest international standard for data erasure.
WIPERAPP supports Purge methods like: Security Enhanced Erase, Block Erase, Crypto Scramble Erase
Additionally, WIPERAPP supports overwrite methods created 25 years ago (last updated in year 2006):
- U.S. National Industrial Security Program Operating Manual (DoD 5220.22-M) (3 passes: random, complement, random)
- U.S. DoD Unclassified Computer Hard Drive Disposition (18 passes: 6x (random, complement, random))
- U.S. Navy Staff Office Publication NAVSO P-5239-26 (3 passes: random, complement, random)
- U.S. Air Force System Security Instruction 5020 (3 passes: 0x00, 0xFF, random)
- British HMG Infosec Standard 5, Baseline Standard (2 passes: 0x00, random)
- British HMG Infosec Standard 5, Enhanced Standard (3 passes: 0x00, 0xFF, random)
- Bruce Schneier’s Algorithm (7 passes: 0xFF, 0x00, random, random, random, random, random)
- German Federal Office for Information Security (4 passes: random, complement, random, complement)
- Communications Security Establishment Canada ITSG-06 (3 passes: 0xFF, complement, randoms)
randoms - pseudo-random 8 characters string
random - random number from 0x00 to 0xFF range
complement - binary negation of previous pass number
complements - binary negation of previous pass string
Operator also can select custom media overwrite method, select number of passes (1-16 passes) and overwrite pattern (0x00, 0xFF, random)
