Study Notes
Cryptographic Erase
- Cryptographic erase, often called crypto erase, is a data sanitization method.
- It permanently removes data from storage devices.
- Data is overwritten with cryptographic keys and algorithms.
- This process makes data recovery extremely difficult, even with sophisticated tools.
