Process Change Detection System is a script to monitor changes in processes--not to monitor if your Web server is still running, but to see if there are new programs running. When debugging a honeypot logging, you often see that there's an extra inetd running, to open up a backdoor port. Or, less dramatically, people login to a system and "forget" to logout.
Shared Crypto System gives the user option to effectively transparently encrypt files on a shared network filesystem, without directly knowing which communication partner will open the file, without needing to share a keypair. It uses Blowfish encryption and one "key" (the passphrase) to decrypt the files. This prevents the hassle of sharing lots of keys and choosing which key to use. It also has an option to recode using a new "key", if for some reason the old key is no longer trusted.
