What I like about apg is that it also provides a basic phonic for each password you can generate that helps you to remember your password. As you may already know, having completely ambiguous random passwords isn't necessarily the best thing to use since most users will tend to write them down on paper somewhere and defeat the real purpose for generating good secure passwords in the first place. Here is a small script that can generate these passwords via a web interface which is quite nice. It does require that you have a ksh shell however since it was written with this shell in mind. #!/usr/local/bin/ksh93 PATH=/bin:/user/bin:/usr/local/bin:/; export PATH umask 077 a=/tmp/apg.$RANDOM b=/tmp/apg.$RAMDOM cat << EOF Content-type: text/html <!DOCTYPE html PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html> <head> <title>Help generating a new password</title> </head> <body> <h3>Help generating a new password</h3> <blockquote> These passwords should be reasonably safe.
