I'm currently using BetterLeaks and implemented a secret scanner into my Git Pipeline. I also made a local scanner which I run over my code before commiting to be better save than sorry.

I still go over the files just in case the scanner missed something, like today: I have over 40 regex rules for my betterleaks.toml and still it struggles with single characters with multiple words like "XyzServerPassword".

Which regex rule is recommendable for these types of characters?
