### Install

```

go get github.com/prongbang/lazynacl

```

### Benchmark

```shell

BenchmarkLazyNacl_Encrypt-10                       27480             42659 ns/op

BenchmarkLazyNacl_Decrypt-10                       28411             42298 ns/op

BenchmarkLazyNacl_EncryptPrecompute-10             28120             42594 ns/op

BenchmarkLazyNacl_DecryptPrecompute-10             28603             42268 ns/op

```

### How to use

- Create KeyPair

```go

keyPair := lazynacl.NewKeyPair()

```

- Key Exchange

```go

clientKp := lazynacl.NewKeyPair()

serverKp := lazynacl.NewKeyPair()

clientSharedKey := lazynacl.KeyPair{

  Pk: serverKeyPair.Pk,

  Sk: clientKeyPair.Sk,

}

serverSharedKey := lazynacl.KeyPair{

  Pk: clientKeyPair.Pk,

  Sk: serverKeyPair.Sk,

}

```

- Encrypt

```go

plaintext := `Plaintext`

ciphertext, err := lazynacl.EncryptPrecompute(plaintext, clientSharedKey)

```

- Decrypt

```go

ciphertext := "ae76477791140129a083a09ff68d5b10460f125c9affdefff48d52d30d774a7c3f42f364ea581eb9b114a65cdbf535171a"

plaintext, err := lazyEzee.DecryptPrecompute(ciphertext, serverSharedKey)

```
