Using recovery key on erased FileVault encrypted SSD
Your data is unrecoverable in the hands of an average data recovery attempt. First step Data Recovery. Low class data recovery doesn’t recovery everything and can scramble some files making decrypting the files very difficult. Nearly impossible without the recovery key. If the recovery key is known it’s, possible. This is very time and resource consuming and very difficult to target specific data. However If an organization wants to spend an astronomical amount of money to extract and decrypt data they pretty much can unless you destroy the disk. Zeroing out a drive makes it harder for the data to be recovered but takes a very long time and puts a lot of ware and tear on the disk.
