comment How to use salt when there is only one user
I understand options 1 and 2. But how would option 3 be more secure? The amount of data encrypted with my passphrase-based key would be (much) smaller, but why does that make the encryption harder to crack?

I am using a passphrase, not a password. Just updated the question accordingly.

This is not quite clear to me yet. If an attacker managed to find the passphrase, which is the same for all files, he would be able to decrypt all files, because their salts are public. It wouldn't matter what the individual salts are. Wouldn't security even decrease with individual salts, because there is a slight increase in chances that one of the attacker's rainbow tables can be used?
