Here is a program I found in the usenet archives which will do some of the splitting and merging features. Note that the merge is smart in that you just cat the pieces together and process them. The main feature of the prog is that you can reconstruct even with a few missing pieces, necessary because of the unreliability of remailer email. I don't think the splitting is cryptographically strong, but each piece could be separately encrypted if desired. You can also get shade from either ftp.wimsey.bc.ca:/pub/crypto/software/dist/???????/Misc/shade.tar.gz and shade.patch.gz or ftp.dsi.unimi.it:/pub/security/crypt/code/shade.tar.gz

If you're outside the U.S. and Canada please use the Italian site.
