There are times however where I need to generate a strong password but I don’t have KeePassX (or any other KeePass implementation) immediately available to me.
There are many different ways to generate strong passwords on a Linux system. If you Google for a solution, you’ll find a number of completely different solutions, of varying levels of complexity.
Ideally, the password generation tool (or process) should be/have:
- Easy to acquire (preferably through a distributions official repo)
- Minimal dependencies
- Simple to remember and use
- Widely available (across different distributions)
I recommend “pwgen” because its:
- Available in the official Debian and Ubuntu repositories, and it’s available through EPEL for CentOS.
- Only has a single dependency, libc
- Simple enough. To generate a single, secure, with special characters/symbols, password of a length of 25 characters:
pwgen -N1 -s -y 25
- Available in Ubuntu, Debian and CentOS — which is a good start and is enough for my requirements. pcgen’s minimal set of dependencies probably mean that it’s very portable too.
- Bonus: It’s written by Ted Ts’o — which helps to add legitimacy to the program’s security
