go-subkey

Subkey port in Go

Usage

Generate Key pair

Sr25519

    kr, err := sr25519.Scheme{}.Generate()

Ed25519

    kr, err := ed25519.Scheme{}.Generate()

Ecdsa

    kr, err := ecdsa.Scheme{}.Generate()

Deriving keypair from a mnemonic or seed

Mnemonic

    uri := "crowd swamp sniff machine grid pretty client emotion banana cricket flush soap//foo//42///password"
    scheme := sr25519.Scheme{}
    kr, err := subkey.DeriveKeyPair(scheme, uri)

Hex encoded Seed

    uri := "0x6ea8835d60351a39a1e2293b2902d7bd6e12e526e72c46f4fda4a233809c4379"
    scheme := sr25519.Scheme{}
    kr, err := subkey.DeriveKeyPair(scheme, uri)

Hex encoded Seed with derivation

    uri := "0x6ea8835d60351a39a1e2293b2902d7bd6e12e526e72c46f4fda4a233809c4379//foo//42///password"
    scheme := sr25519.Scheme{}
    kr, err := subkey.DeriveKeyPair(scheme, uri)

Sign and verify using Keypair

    kr, err := ed25519.Scheme{}.Generate()
    msg := []byte("test message")
    sig, err := kr.Sign(msg)
    ok := kr.Verify(msg, sig)
