SesameGen is just another password generator.
- Uses the secrets module to pick secure random passwords.
- Only uses standard Python3 libraries. (tkinter for GUI)
- Fast
- Simple
- Does what it says on the tin.
There are lots out there and many that have much more features than this one but it wrote it because I wanted a couple of things.
- A light weight tool which starts quickly and generates passwords when as soon as you start it.
I think the password generator in KeePassX for example is great, but the current version (at the time of this writing) you can't access the generator until you have opened your database.
The one in LastPass is also good but again is hidden under layers of menus. Or if you use the public one it keeps popping up asking you to sign up.
SesameGen runs with only the standard Python libraries.
- A tool which reports the entropy accurately.
If I'm being truly honest, this is my biggest bugbear with almost all the password generators I've used before. They measure the entropy based on the output of their system rather than the input. For example if you open the KeePass generator and run it a few times with the same settings you will get a different entropy score each time.
This is because it's based on what appears in the output section. You can edit the output to 'AAAAAAAA' and it will update with a low score.
That's probably a good way of showing things but it's not right. SesameGen on the other hand show how many bits would be needed for the whole key space.
For example if you pick 8 characters, upper and lower case with numbers
it could produce AAAAAAAA or 4Nr8Ik7z with equal probably. You can't
just discount AAAAAAAA because it doesn't feel random enough. It's
part of the possible outputs and removing outputs like this would
actually reduce the keyspace. In SesameGen either of those outputs would
show as 47.6 bits of entropy to produce either output.
