This script implements vim commands RandpadPad and RandpadRePad.
RandpadPad inserts a long line containing random characters before the first
and last line of the buffer. The file is padded to a size which is multiple of
g:RandPadBlocksize (default 4096 bytes).
The length of the first random string is between 0.25 and 0.5 times
g:RandPadBlocksize. The second random string fills the buffer to a multiple
of the block size, but has a length of at least 0.125 times (1/8th of)
g:RandPadBlocksize.
RandpadRePad replaces an existing padding with new random strings.
Files which match g:RandpadFilePattern (which defaults to *.rpad and
*.rp) are automatically padded when created and re-padded when saving.
Random padding may be useful when storing encrypted files with small incremental changes in content (e.g. lists of passwords) repeatedly to version control.
For GnuPG encryption of files with vim, see vim-gnupg.
Just clone or copy to ~/.vim/pack/randpad/start/ on vim 8 or later, or use
your favorite
plugin manager.
