Thank you for the replies. I understand now.How safe is the reencrypt process? Is there data file ever exposed while it is reencrypted?
Encrypted data in decrypted form are in:
- buffer pool
- RAM
- swap file
- and i don't know where else
Encryption is on page level, so probably reencrypt occur as follow: read a page->decrypt->encrypt by a new key->write a page
But why are you so afraid about encryption process?
