GPG to symmetrically encrypt multiple files, and it would be more convenient if they all had the same strong passphrase. It's possible that someone could gain access to several of these files.
In this situation, I don't care if getting the passphrase for one of the files gives access to the others as well.
Is it safe to use the same GPG symmetric passphrase for multiple files ?
If needed, please assume
--s2k-digest-algo SHA512 and
