Bitcoin Bip322 Signer

This tool is aiming to simplify message signing process on bitcoin. This was tested on subber.

Simply pass private key in WIF format and message:

simple_signature_with_wif_segwit(message: &str, wif: &str) -> &str
simple_signature_with_wif_taproot(message: &str, wif: &str) -> &str

Currently only Nested Segwit and Taproot addresses are supported. Support for other address types will be added if there will be need for them.

        wif: *const c_char,
    ) -> *const c_char

pub extern "C" fn signature_with_wif_taproot(
        message: *const c_char,
        wif: *const c_char,
    ) -> *const c_char
