Lamport signatures are a one-time signature scheme. Each key is intended to be used only once.

### Usage

Generate key

``` Go

k, err := lamport.GenerateKey(rand.Reader, crypto.SHA256)

```

Sign message

``` Go

message := []byte("Hello, Lamport!")

messageHash := sha256.Sum256(message)

sig, _ := lamport.Sign(k, messageHash[:])

```

Verify signature

``` Go

if lamport.Verify(&k.PublicKey, messageHash[:], sig); err != nil {

    // signature invalid here

}

```

### Testing & Benchmarking

To test on your machine use:

``` Bash

go test

```

If you want to run the benchmarks:

``` Bash

go test -bench=.

```
