How to

Open Source tool for getting public keys and adding private keys (Do not use for wallets with large value)

Getting public key for mandatory -z parameter

Generate private key and public key via openssl in terminal (remove prefix "04" from public key):

$ openssl ecparam -genkey -name secp256k1 -text -noout -outform DER | xxd -p -c 1000 | sed 's/41534e31204f49443a20736563703235366b310a30740201010420/Private Key: /' | sed 's/a00706052b8104000aa144034200/\'$'\nPublic Key: /'

Derive public key from existing private key via openssl in terminal (remove prefix "04" from public key):

$ openssl ec -inform DER -text -noout -in <(cat <(echo -n "302e0201010420") <(echo -n "PRIVATE_KEY_HEX") <(echo -n "a00706052b8104000a") | xxd -r -p) 2>/dev/null | tail -6 | head -5 | sed 's/[ :]//g' | tr -d '\n' && echo

Adding private keys (never use online calculators!)

Terminal:

Use private keys as 64-symbol hexadecimal string WITHOUT 0x prefix:

(echo 'ibase=16;obase=10' && (echo '(PRIVATE_KEY_A + PRIVATE_KEY_B) % FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2F' | tr '[:lower:]' '[:upper:]')) | bc

Python

Use private keys as 64-symbol hexadecimal string WITH 0x prefix:

$ python3
>>> hex((PRIVATE_KEY_A + PRIVATE_KEY_B) % 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2F)
