## Installation
```bash
# Go client
go get github.com/nats-io/go-nats
# Server
go get github.com/nats-io/gnatsd
```
## Basic Usage
```go
import nats "github.com/nats-io/go-nats"
// Connect to a server
nc, _ := nats.Connect(nats.DefaultURL)
// Simple Publisher
nc.Publish("foo", []byte("Hello World"))
// Simple Async Subscriber
nc.Subscribe("foo", func(m *nats.Msg) {
fmt.Printf("Received a message: %s\n", string(m.Data))
})
// Simple Sync Subscriber
sub, err := nc.SubscribeSync("foo")
m, err := sub.NextMsg(timeout)
// Channel Subscriber
ch := make(chan *nats.Msg, 64)
sub, err := nc.ChanSubscribe("foo", ch)
msg := <- ch
// Unsubscribe
sub.Unsubscribe()
// Drain
sub.Drain()
// Requests
msg, err := nc.Request("help", []byte("help me"), 10*time.Millisecond)
// Replies
nc.Subscribe("help", func(m *Msg) {
nc.Publish(m.Reply, []byte("I can help!"))
})
// Drain connection (Preferred for responders)
// Close() not needed if this is called.
nc.Drain()
// Close connection
nc.Close()
```
## Encoded Connections
```go
nc, _ := nats.Connect(nats.DefaultURL)
c, _ := nats.NewEncodedConn(nc, nats.JSON_ENCODER)
defer c.Close()
// Simple Publisher
c.Publish("foo", "Hello World")
// Simple Async Subscriber
c.Subscribe("foo", func(s string) {
fmt.Printf("Received a message: %s\n", s)
})
// EncodedConn can Publish any raw Go type using the registered Encoder
type person struct {
Name string
Address string
Age int
}
// Go type Subscriber
c.Subscribe("hello", func(p *person) {
fmt.Printf("Received a person: %+v\n", p)
})
me := &person{Name: "derek", Age: 22, Address: "140 New Montgomery Street, San Francisco, CA"}
// Go type Publisher
c.Publish("hello", me)
// Unsubscribe
sub, err := c.Subscribe("foo", nil)
...
sub.Unsubscribe()
// Requests
var response string
err := c.Request("help", "help me", &response, 10*time.Millisecond)
if err != nil {
fmt.Printf("Request failed: %v\n", err)
}
// Replying
c.Subscribe("help", func(subj, reply string, msg string) {
c.Publish(reply, "I can help!")
})
// Close connection
c.Close();
```
## New Authentication (Nkeys and User Credentials)
This requires server with version >= 2.0.0
NATS servers have a new security and authentication mechanism to authenticate with user credentials and Nkeys.
The simplest form is to use the helper method UserCredentials(credsFilepath).
```go
nc, err := nats.Connect(url, UserCredentials("user.creds"))
```
The helper methos creates two callback handlers to present the user JWT and sign the nonce challenge from the server.
The core client library never has direct access to your private key and simply performs the callback for signing the server challenge.
The helper will load and wipe and erase memory it uses for each connect or reconnect.
The helper also can take two entries, one for the JWT and one for the NKey seed file.
```go
nc, err := nats.Connect(url, UserCredentials("user.jwt", "user.nk"))
```
You can also set the callback handlers directly and manage challenge signing directly.
```go
nc, err := nats.Connect(url, UserJWT(jwtCB, sigCB))
```
Bare Nkeys are also supported. The nkey seed should be in a read only file, e.g. seed.txt
```bash
> cat seed.txt
# This is my seed nkey!
SUAGMJH5XLGZKQQWAWKRZJIGMOU4HPFUYLXJMXOO5NLFEO2OOQJ5LPRDPM
```
This is a helper function which will load and decode and do the proper signing for the server nonce.
It will clear memory in between invocations.
You can choose to use the low level option and provide the public key and a signature callback on your own.
```go
opt, err := nats.NkeyOptionFromSeed("seed.txt")
nc, err := nats.Connect(serverUrl, opt)
// Direct
nc, err := nats.Connect(serverUrl, Nkey(pubNkey, sigCB))
```
## TLS
```go
// tls as a scheme will enable secure connections by default. This will also verify the server name.
nc, err := nats.Connect("tls://nats.demo.io:4443")
// If you are using a self-signed certificate, you need to have a tls.Config with RootCAs setup.
// We provide a helper method to make this case easier.
nc, err = nats.Connect("tls://localhost:4443", nats.RootCAs("./configs/certs/ca.pem"))
// If the server requires client certificate, there is an helper function for that too:
cert := nats.ClientCert("./configs/certs/client-cert.pem", "./configs/certs/client-key.pem")
nc, err = nats.Connect("tls://localhost:4443", cert)
// You can also supply a complete tls.Config
certFile := "./configs/certs/client-cert.pem"
keyFile := "./configs/certs/client-key.pem"
cert, err := tls.LoadX509KeyPair(certFile, keyFile)
if err != nil {
t.Fatalf("error parsing X509 certificate/key pair: %v", err)
}
config := &tls.Config{
ServerName: opts.Host,
Certificates: []tls.Certificate{cert},
RootCAs: pool,
MinVersion: tls.VersionTLS12,
}
nc, err = nats.Connect("nats://localhost:4443", nats.Secure(config))
if err != nil {
t.Fatalf("Got an error on Connect with Secure Options: %+v\n", err)
}
```
## Using Go Channels (netchan)
```go
nc, _ := nats.Connect(nats.DefaultURL)
ec, _ := nats.NewEncodedConn(nc, nats.JSON_ENCODER)
defer ec.Close()
type person struct {
Name string
Address string
Age int
}
recvCh := make(chan *person)
ec.BindRecvChan("hello", recvCh)
sendCh := make(chan *person)
ec.BindSendChan("hello", sendCh)
me := &person{Name: "derek", Age: 22, Address: "140 New Montgomery Street"}
// Send via Go channels
sendCh <- me
// Receive via Go channels
who := <- recvCh
```
## Wildcard Subscriptions
```go
// "*" matches any token, at any level of the subject.
nc.Subscribe("foo.*.baz", func(m *Msg) {
fmt.Printf("Msg received on [%s] : %s\n", m.Subject, string(m.Data));
})
nc.Subscribe("foo.bar.*", func(m *Msg) {
fmt.Printf("Msg received on [%s] : %s\n", m.Subject, string(m.Data));
})
// ">" matches any length of the tail of a subject, and can only be the last token
// E.g. 'foo.>' will match 'foo.bar', 'foo.bar.baz', 'foo.foo.bar.bax.22'
nc.Subscribe("foo.>", func(m *Msg) {
fmt.Printf("Msg received on [%s] : %s\n", m.Subject, string(m.Data));
})
// Matches all of the above
nc.Publish("foo.bar.baz", []byte("Hello World"))
```
## Queue Groups
```go
// All subscriptions with the same queue name will form a queue group.
// Each message will be delivered to only one subscriber per queue group,
// using queuing semantics. You can have as many queue groups as you wish.
// Normal subscribers will continue to work as expected.
nc.QueueSubscribe("foo", "job_workers", func(_ *Msg) {
received += 1;
})
```
## Advanced Usage
```go
// Flush connection to server, returns when all messages have been processed.
nc.Flush()
fmt.Println("All clear!")
// FlushTimeout specifies a timeout value as well.
err := nc.FlushTimeout(1*time.Second)
if err != nil {
fmt.Println("All clear!")
} else {
fmt.Println("Flushed timed out!")
}
// Auto-unsubscribe after MAX_WANTED messages received
const MAX_WANTED = 10
sub, err := nc.Subscribe("foo")
sub.AutoUnsubscribe(MAX_WANTED)
// Multiple connections
nc1 := nats.Connect("nats://host1:4222")
nc2 := nats.Connect("nats://host2:4222")
nc1.Subscribe("foo", func(m *Msg) {
fmt.Printf("Received a message: %s\n", string(m.Data))
})
nc2.Publish("foo", []byte("Hello World!"));
```
## Clustered Usage
```go
var servers = "nats://localhost:1222, nats://localhost:1223, nats://localhost:1224"
nc, err := nats.Connect(servers)
// Optionally set ReconnectWait and MaxReconnect attempts.
// This example means 10 seconds total per backend.

A public-key signature system based on [Ed25519](https://ed25519.cr.yp.to/) for the NATS ecosystem.
## About
The NATS ecosystem will be moving to [Ed25519](https://ed25519.cr.yp.to/) keys for identity, authentication and authorization for entities such as Accounts, Users, Servers and Clusters.
Ed25519 is fast and resistant to side channel attacks. Generation of a seed key is all that is needed to be stored and kept safe, as the seed can generate both the public and private keys.
The NATS system will utilize Ed25519 keys, meaning that NATS systems will never store or even have access to any private keys. Authentication will utilize a random challenge response mechanism.
Dealing with 32 byte and 64 byte raw keys can be challenging. NKEYS is designed to formulate keys in a much friendlier fashion and references work done in cryptocurrencies, specifically [Stellar](https://www.stellar.org/). Bitcoin and others used a form of Base58 (or Base58Check) to endode raw keys. Stellar utilized a more traditonal Base32 with a CRC16 and a version or prefix byte. NKEYS utilizes a similar format where the prefix will be 1 byte for public and private keys and will be 2 bytes for seeds. The base32 encoding of these prefixes will yield friendly human readbable prefixes, e.g. '**N**' = server, '**C**' = cluster, '**O**' = operator, '**A**' = account, and '**U**' = user. '**P**' is used for private keys. For seeds, the first encoded prefix is '**S**', and the second character will be the type for the public key, e.g. "**SU**" is a seed for a user key pair, "**SA**" is a seed for an account key pair.
## Installation
Use the `go` command:
$ go get github.com/nats-io/nkeys
## nk - Command Line Utility
Located under the nk [directory](https://github.com/nats-io/nkeys/tree/master/nk).
## Basic API Usage
```go
// Create a new User KeyPair
user, _ := nkeys.CreateUser()
// Sign some data with a full key pair user.
data := []byte("Hello World")
sig, _ := user.Sign(data)
// Verify the signature.
err = user.Verify(data, sig)
// Access the seed, the only thing that needs to be stored and kept safe.
// seed = "SUAKYRHVIOREXV7EUZTBHUHL7NUMHPMAS7QMDU3GTIUWEI5LDNOXD43IZY"
seed, _ := user.Seed()
// Access the public key which can be shared.
// publicKey = "UD466L6EBCM3YY5HEGHJANNTN4LSKTSUXTH7RILHCKEQMQHTBNLHJJXT"
publicKey, _ := user.PublicKey()
// Create a full User who can sign and verify from a private seed.
user, _ = nkeys.FromSeed(seed)
// Create a User who can only verify signatures via a public key.
user, _ = nkeys.FromPublicKey(publicKey)
// Create a User KeyPair with our own random data.
var rawSeed [32]byte
_, err := io.ReadFull(rand.Reader, rawSeed[:]) // Or some other random source.
user2, _ := nkeys.FromRawSeed(PrefixByteUser, rawSeed)

[![Coverage Status](https://coveralls.io/repos/github/nats-io/nuid/badge.svg?branch=master)](https://coveralls.io/github/nats-io/nuid?branch=master)
A highly performant unique identifier generator.
## Installation
Use the `go` command:
$ go get github.com/nats-io/nuid
## Basic Usage
```go
// Utilize the global locked instance
nuid := nuid.Next()
// Create an instance, these are not locked.
n := nuid.New()
nuid = n.Next()
// Generate a new crypto/rand seeded prefix.
// Generally not needed, happens automatically.
n.RandomizePrefix()
```
## Performance
NUID needs to be very fast to generate and be truly unique, all while being entropy pool friendly.
NUID uses 12 bytes of crypto generated data (entropy draining), and 10 bytes of pseudo-random
sequential data that increments with a pseudo-random increment.
Total length of a NUID string is 22 bytes of base 62 ascii text, so 62^22 or
2707803647802660400290261537185326956544 possibilities.
NUID can generate identifiers as fast as 60ns, or ~16 million per second. There is an associated
benchmark you can use to test performance on your own hardware.
