Prosecutors stressed that they don't actually require the passphrase itself, meaning Fricosu would be permitted to type it in and unlock the files without anyone looking over her shoulder.
I wonder if anyone has thought of using more than one keys as a decryption possibility. I've always considered it, but never figured there'd be too much use. Say, have one correct key to decrypts data stored in one way, and another key to either "decrypts" into a pre-generated text, or another variation of what's stored. I guess it latter might be too content dependent.
