can't even describe lol tell me what is so hard to understand? my first post on this topic gives the clear concept of what I want you don't know English now?
As a native English speaker, I find it difficult to understand what you have written because your grammar and punctuation (which are important components of the language) are poor to non-existent.
If I understand you correctly, you would like someone to create a vanity address generator that returns a number,
N, such that the address for the private key begins with
P, where the private key comes from SHA256(
M|
N), and
M and
P are a string and a desired prefix, both chosen by the user.
That is certainly doable, but keep in mind that as others have mentioned, a brain wallet is insecure. That includes your derivation.
