encrypt turns any plaintext word into an encrypted string in a variety of ways, including reading a random word from a file. It can be useful for creating passwords for .htpasswd files for webservers. It's also very useful for generating random passwords out of a cronjob.
The program has also and a man page.
But most people will use it like this:
encrypt -s 'dZ' mypassword
Or you can have it generate a random password for you:
encrypt -r 8
Check out the man page 'man encrypt' for more information and examples.
Any user will be able to use encrypt in their own userspace. You can also run 'make install' as root and it will put the program, man page and config file in the locations specified in the Makefile. You may want to run 'make test' first to make sure you have everything that is needed to run the program first.
