A recursive checksum? I wouldn't know how to do that.

I suggest some features for vim improvement.
In my humble opinion, the next thing to do is to enhance vim's encryption. It could implement more encrypt methods like CAST5, TWOFISH, AES256 etc. One studpid feature is that vim prepends a 'magic string' --- 'VimCrypt~..' on the encrypted file, which is COMPLETELY no use except for telling crackers that it is encrypted with vim and its encrypt method. Vim encrypted file should get rid of any thing that would reveal it is vim encrypted and its encrypt method. Then, how to read it back? Vim will never know if it is vim encrypted and the encrypt method. It is easy. First, vim will read in an encrypted file and display a mess with binary mode. Sceond, the user inputs command like ':Z blowfish' or ':Z cast5' in vim, which tells vim to decrypt the mess with blowfish or cast5. If that file is not vim encrypted but an real executable or user has inputted a wrong key, vim still uses that key to decrypt and another mess would display. This will greatly improve the robustness of vim encrypted file. By enhancing its encryption in this way, vim could greatly spread over the world and other editors become truly nothing. Vim becomes a weapon with deity.
By the way, the improvement of vim should never stop. If it stops, then vim will perish --- definitely. But the degree of improvement could vary. This is one stripe of balance, which we have been seeking in the universe.
