# sqlcertcache

SQL cache for [acme/autocert](https://godoc.org/golang.org/x/crypto/acme/autocert) written in Go.

## Example

```go

conn, err := sql.Open("postgres", "postgres://YOUR_CONNECTION_STRING")

if err != nil {

  // Handle error

}

cache, err := sqlcertcache.New(conn, "autocert_cache")

if err != nil {

  // Handle error

}

m := autocert.Manager{

  Prompt:     autocert.AcceptTOS,

  HostPolicy: autocert.HostWhitelist("example.org"),

  Cache:      cache,

}

s := &http.Server{

  Addr:      ":https",

  TLSConfig: &tls.Config{GetCertificate: m.GetCertificate},

}

s.ListenAndServeTLS("", "")

```

## Performance

This is just a reminder that autocert has an internal in-memory cache that is used before quering this long-term cache.

So you don't need to worry about your SQL database being hit many times just to get a certificate. It should only do once per process+key.
