Re: [O] org-crypt: Secure encrypted message against inadvertent change
If it helps, though aside from the question, all GPG lines (except the last 2) are 64 chars(if memory serves). A little scripting and decryption should be plausible (possible in reasonable time), especially if chars were only added and not deleted/changed.
