Hello,

I am looking for an effective method to scan a large dictionary (about 1GB) in terms of checking the use of its phrases as a brainwallet. Of course, I don't think any of the phrases will contain anything else, but I am asking for statistical purposes on the basis of a private phrase database.
I was able to find https://github.com/j4rj4r/Bitcoin-Brainwallet-Bruteforce, but the checking speed is not entirely satisfactory (I know ... due to API limitations), but it also does not indicate any data on whether the phrase was used as a brainwallet at all times, and in general I have doubts as to whether the above script works.
It doesn't have to be in Python ... it could also be C, C ++

Regards
