I have been using ccrypt for my encryption needs for quite a while now. I have mainly used it on my desktop but recently I wanted to install it on my lappy. The README that comes with the package can walk you through the steps pretty well but I did have to do some investigating to get it installed. After unpacking the latest version of ccrypt for OS X open terminal and type “echo $PATH” to determine where OS X will be looking for executables. This is my output on 10.4 “/bin:/sbin:/usr/bin:/usr/sbin” . I then copied the ccrypt executable to /usr/bin and while in that directory made a couple of symlinks by typing these three separate commands

sudo ln -s ccrypt ccencrypt
sudo ln -s ccrypt ccdecrypt
sudo ln -s ccrypt ccat

I then wanted to install my man page for ccrypt. You can find your man page path by typing “manpath“. This is my output: “/usr/share/man:/usr/local/share/man:/usr/X11R6/man”
I then copied “ccrypt.1” to “/usr/share/man/man1” so that now when I type “man ccrypt” in terminal it will output the man page. Now you are ready to encrypt some files!! Make sure you remember your encryption key because there is no way to recover a encrypted file with out the encryption key. This is why you encrypted them in the first place.
