Are there any cygwin/Windows programs that will encrypt a file, but leave it usable, similar to what TrueCrypt does for filesystems?
TrueCrypt takes a large file (call it "encryptfs") and mounts it on a drive (call it "M:"). After you enter your passphrase, Windows sees M: as a normal drive. However, encryptfs is still encrypted, and you can copy it to make encrypted backups. This is great in theory, but has some problems in practise: % Even w/ rsync, even using --partial, copying over a large file is slow and prone to errors. % You have to unmount "encryptfs" to back it up; otherwise, Windows says the file is busy. So, I was looking for a file-by-file solution, where "encrypt1" would be an encrypted file, and "myfile" would be a psuedo-file based on encrypt1 that Windows would see as a regular file. -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology.
