It might be safest to use GnuPG, the Gnu Privacy Guard. For you case using one of its Symmetric ciphers to encypt the file should be sufficient. You can also consider using Public-key ciphers which it also supports. The cygwin package containing it is someting like "gpg (GnuPG) 1.4.9". regards -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

File by file encryption instead of filesystem encryption
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.
