Cryptographic erasure (often abbreviated as Crypto Erase) is one of the three methods that can achieve data sanitization. It has proven to be extremely effective at making data unrecoverable if the proper steps are in place and verification and certification are achieved. Here’s how:
This method erases the encryption key of a self-encrypting drive. The encryption algorithm must be at a minimum of 128 bit for the process to be successful. While the data remains on the storage device itself, by erasing the original key, the data is effectively impossible to decrypt. Thus, the data is rendered unrecoverable.
Like any data sanitization method, there are advantages and disadvantages to using cryptographic erasure.

All organizations must determine their unique risk tolerance to decide which data sanitization method(s) is right for them.
