### Algorithm details
- Key exchange: X25519
- Encryption: ChaCha20
- Authentication: Poly1305
### Install
```
go get github.com/prongbang/lazychacha
```
### Benchmark
```shell
BenchmarkEncrypt-10 1347146 872.2 ns/op 864 B/op 5 allocs/op
BenchmarkDecrypt-10 2088066 577.9 ns/op 544 B/op 4 allocs/op
```
### How to use
- Generate KeyPair
```go
keyPair := lazychacha.NewKeyPair()
```
- Key Exchange
```go
clientKp := lazychacha.NewKeyPair()
serverKp := lazychacha.NewKeyPair()
serverKx := serverKp.Exchange(clientKp.Pk)
clientKx := clientKp.Exchange(serverKp.Pk)
```
- Shared Key
```go
serverSharedKey, _ := serverKx.Secret()
clientSharedKey, _ := clientKx.Secret()
```
- Encrypt
```go
lazyChacha := lazychacha.New()
sharedKey, _ := clientKx.Secret()
key, _ := hex.DecodeString(sharedKey)
plaintext := "text"
ciphertext, err := lazyChacha.Encrypt(plaintext, key)
```
- Decrypt
```go
lazyChacha := lazychacha.New()
sharedKey, _ := serverKx.Secret()
key, _ := hex.DecodeString(sharedKey)
ciphertext := "f6a1bd8"
plaintext, err := lazyChacha.Decrypt(ciphertext, key)
```
