If the disk is encrypted how can they match file hashes? Do they encrypt known CP files with the FileVault key and then compare? If so, isn't that enough to convict him?

#12`Investigators said content stored on the encrypted hard drive matched file hashes for known child pornography content.` Well there's the reasoning
that makes 0 sense, if the files are encrypted they cannot be a match

#13The accused crime is heinous and there is some evidence against him stated in the article but common, an indefinite jail sentence with no conviction? Then people wonder why the country elects Trump to shake things up. This guy should stand trial or be let go.
Trump quite explicitely promised to double on police and prosecutor power. If what you want is better protection for accused, Trump is last person you should vote for.

This shouldn't work because if they had the key (which should be encrypted with the password) then they could also just decrypt the rest.
Somebody on IRC said that maybe the encrypted filesystem saves hashes of the files unencrypted, but not sure if Apple's FileVault does this.

Isn't the point of encryption that it doesn't create a reliable hash - that 2 identical files will appear different while encrypted, as part of the larger encrypted drive?
Or are encrypted-hash collisions possible when small files are encrypted individually?

Serious question for those who know about crypto, do drive encryption systems allow to retrieve hashes for the encrypted files?
