Within the context of the Compare - Encrypted Email Service Providers I was asked:
It means that a provider can't read OR decrypt the content/attachments of emails stored on its servers.
An example is SCRYPTmail. SCRYPTmail encrypts user objects and emails with a key provided by the user that never sent to SCRYPTmail, so they can’t decrypt it.
Does "AES-256 encrypted storage" mean that a provider can't read OR decrypt the content/attachments of emails (which remains on its servers) ?
