PublicKey
Derives the compressed/uncompressed public key and coordinates from a private key.
Derives the full public key (and its raw X, Y coordinates) from a private key.
What it does
- •Multiplies the private key by the curve generator point G.
- •Outputs both compressed (33-byte) and uncompressed (65-byte) public key encodings.
- •Shows the raw X and Y coordinates of the resulting curve point.
Use cases
- •Get the public key to share (e.g. for multisig setup) without exposing the private key.
- •Feed the resulting public key into PubkeyAdd, PublicKey - HEX, or the ECC Calculator.
- •See the actual elliptic curve point behind a key pair.
