Some scripts written c using libwally to be used with bitcoin core. Everything is compiled locally and linked statically, so there are no external dependecies apart from the c standard library. Bitscriptc is just a simple wrapper around libwally.
Main scripts are for generating a bip39 and converting it to xprv and xpub, and for signing a message with the private key of an address.
The idea for the generations scripts is to have the most simple and with less dependencies way to generate a bip39 mnemonics/bip32 xpub, xprv.
The idea for the signing scripts is that bitcoin core's signmessage
and signmessagewithprivkey do not support
bip-0322,
so they only work with legacy addresses (see
here).
The scripts help with signing from any addresses with bitcoin core in a
minimal way and with less dependencies possible.
Completions for bash are in completions/bitscriptc.bash-completion

make
# if you also want to install
