I'm using gpg in a simple 4-lines script to encrypt some important files.
But i'm lazy and like to use short passwords, especially for often-used files, which generates weak encryption-at-rest.

Now the idea in the title for a second iteration, maybe with a different algorythm: would the generated file be easier to crack or harder than once with a weak password?

Um. If you use the file encrypted with a weak keyphrase a the key for a second round, how would you decrypt the result unless you keep the first-stage encrypted file around, thus defeating the purpose?
