Allow a multi-character prefix to be given, rather than a byte value.

For greater flexibility, it would be nice to be able to specify a character prefix of arbitrary length, rather than a byte value.

Thank you for the contribution, but you misunderstood the program a little 😅 It will look for the specified byte, which is repeated, meaning it will search this way starting from 55.... and then 5555.... -> 555555... and so on. Similar to finding as much 0s as possible for an Ethereum address.

If you want to add your functionality, it'd be great if you implemented a check against uint8 buffer here

But honestly this generator was written for fun. And for a serious approach it needs to be rewritten in C instead.

I didn't misunderstand how the program works. I just thought it would be more useful to be able to specify a prefix, rather than a single repeated byte. We're talking about vanity here, after all. 😉

Yes, but it won't be run very often by any one user, so the unserious approach is a fair one, I think. It also allows a good amount of code reuse from Session.

In this case, please consider implementing this as an additional mode, rather than replacing the current one, as they have different applications.

And regarding C implementation, it would be even more convenient for users if there were pre-built binary releases than dealing with JS as now.
