Hedera.PrivateKey (Hedera v0.2.0)

Copy Markdown View Source

A Hedera private key — Ed25519 or ECDSA secp256k1.

Signing follows Hedera's conventions: Ed25519 signs the message bytes directly; ECDSA secp256k1 signs the Keccak-256 digest of the message and returns the canonical 64-byte r ‖ s (low-S) signature.
