hesela.devPurge sanitization
Purge sanitization uses suitable logical or physical techniques to make target-data recovery infeasible even with current state-of-the-art laboratory techniques while potentially allowing the medium to be reused.
NIST SP 800-88 Rev. 2 section 3.1.2 defines an assurance objective, not a synonym for a particular erase command. Cryptographic erase can be a purge technique when its prerequisites are met. Reuse is possible, not guaranteed: a physical purge technique can leave some media inoperable. Degaussing requires a magnetic field suited to the medium's coercivity, does not sanitize flash components (including those in hybrid devices), and is not classified as destroy merely because hardware stops working.

- data-sanitization, clear-sanitization, destroy-sanitization, cryptographic-erase, sanitization-verification, sanitization-validation
Advantages
- Can provide a higher recovery-resistance objective than clear without necessarily destroying reusable media. [1]
Limitations
- A technique must be appropriate for the medium and implementation; command acceptance alone does not establish successful purge. [1]
