[](https://pkg.go.dev/github.com/vedhavyas/go-subkey)
Subkey port in Go
## Usage
### Generate Key pair
#### Sr25519
```go
kr, err := sr25519.Scheme{}.Generate()
```
#### Ed25519
```go
kr, err := ed25519.Scheme{}.Generate()
```
#### Ecdsa
```go
kr, err := ecdsa.Scheme{}.Generate()
```
### Deriving keypair from a mnemonic or seed
#### Mnemonic
```go
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
```go
uri := "0x6ea8835d60351a39a1e2293b2902d7bd6e12e526e72c46f4fda4a233809c4379"
scheme := sr25519.Scheme{}
kr, err := subkey.DeriveKeyPair(scheme, uri)
```
#### Hex encoded Seed with derivation
```go
uri := "0x6ea8835d60351a39a1e2293b2902d7bd6e12e526e72c46f4fda4a233809c4379//foo//42///password"
scheme := sr25519.Scheme{}
kr, err := subkey.DeriveKeyPair(scheme, uri)
```
### Sign and verify using Keypair
```go
kr, err := ed25519.Scheme{}.Generate()
msg := []byte("test message")
sig, err := kr.Sign(msg)
ok := kr.Verify(msg, sig)
```
