Why is it said that recovery of data after a cryptographic erase is nearly impossible?
Why is it said that recovery of data after a cryptographic erase is nearly impossible?
- Because cryptographic algorithms overwrite the original data (correct)
- Because the storage device is reformatted
- Because specialized software can always recover it
- Because data is moved to a different storage device

Study Notes
Cryptographic Erase
- Cryptographic erase, or crypto erase, is a method used to permanently remove data from storage devices, like hard drives and SSDs.
- The process overwrites the data with cryptographic keys and algorithms, making it extremely difficult to recover even with advanced tools.
- This method ensures data is truly erased, as opposed to simply deleting files that can be recovered using data recovery software.
