# merkletree

A thread safe merkle tree for golang

# Usage

```go

package main

import (

    "crypto/sha256"

    "fmt"

    "github.com/purehyperbole/merkletree"

)

func main() {

    m := merkletree.New(1024, func() hash.Hash {

        return sha256.New()

    })

    // insert the hashes of some values into the tree

    // the hash of the value will be returned

    h1 := m.Insert([]byte("my data 1"))

    h2 := m.Insert([]byte("my data 2"))

    h3 := m.Insert([]byte("my data 3"))

    // generate the merkle root hash. Note, this can only be called once

    mrh := m.Root()

    // generate a proof for 'my data 2' from the generated merkle tree

    proof, err := m.Proof(h2)

    if err != nil {

        panic(err)

    }

    // validate the proof against the hash of the value and merkle root

    err = merkletree.Validate(sha256.New(), h2, mrh, proof)

    if err != nil {

        panic(err)

    }

}

```
