  1. BITCOIN_PRIVATE_KEY name may be misleading. There is the hex representation of ECDSA key in the script above. In contrast Bitcoin private keys are typically represented in WIF format (Base58Check encoding) like exported from Bitcoin Core and imported by many wallets.

There is the script that converts keys genereted by OpenSSL to Bitcoin Wallet Import Format (WIF): https://gist.github.com/GregTonoski/438992249df6e4bd613f9758421ff38a
