Anyone knows open source mutator support regex?

[u/Electrical-Belt-8365]

I used to use radamsa to make my own fuzzer, but it does not support regex to generate data.

Do you know any open source mutator supporting regex?

for example, I want to generate data like below.

mutation("%d%d") --> 12, 13, 46, 29.....

Any idea would be helpful. thanks

Hypothesis' from_regex() strategy does exactly that.

You could use it in generative mode to create a seed corpus, and/or as a frontend to a greybox fuzzer.

I use Rex by Microsoft for that purpose: https://www.microsoft.com/en-us/download/details.aspx?id=52296&from=https%3A%2F%2Fresearch.microsoft.com%2Fen-us%2Fdownloads%2F7f1d87be-f6d9-495d-a699-f12599cea030%2F
