Import 256 bit private key

Question

Can I import a 256 bit private key in a Wallet (binary format)? Or do I have to convert it in another format?

It all depends on the wallet, sometimes it's not possible to directly import a private key, sometimes it uses some specific format (for example WIF for Bitcoin Core). I think you should be more specific or really we can't help much. — Sosthène, Sep 29 '20 at 16:08

Most wallets (and by that, I mean almost all) will not accept a binary 256 bit private key, you will have to convert your 1's and 0's to a WIF format.

There are libraries in python and javascript (and I'm sure other languages too) available that can do this function conversion for you.
