Interesting password complexity tables

  • SpinRite v6.1 Release #3
    The 3rd release of SpinRite v6.1 is published and may be obtained by all SpinRite v6.0 owners at the SpinRite v6.1 Pre-Release page. (SpinRite will shortly be officially updated to v6.1 so this page will be renamed.) The primary new feature, and the reason for this release, was the discovery of memory problems in some systems that were affecting SpinRite's operation. So SpinRite now incorporates a built-in test of the system's memory. For the full story, please see this page in the "Pre-Release Announcements & Feedback" forum.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

    (You may permanently close this reminder with the 'X' in the upper right.)

I came across this blog post and thought it might be of interest to others. These tables could be useful in explaining password entropy:
In 2023 it's really pretty simple. You should not be generating passwords any more, you should be using a password manager. It's then easy to create a password that is 32 or more random characters for every site and you won't reuse them. This table then applies only to your master password for your password manager, and for that you should probably consider a lengthy pass phrase (25+ characters.) How to come up with good, secure, memorable pass phrases has been covered elsewhere.
The article is a 2023 update. The image that is embedded compares the RTX 2080, 3090, and 4090.

Later on, they compare the 4090 to 8 A100 GPUs you can rent from AWS, showing how much the color goes down the scale.

They are making the data. The table in the post above is for md5, they made tables using bcrypt comparing the 3090 to the 8 A100
