+# PKCS#11 [![Build Status](https://travis-ci.org/miekg/pkcs11.png?branch=master)](https://travis-ci.org/miekg/pkcs11) [![GoDoc](https://img.shields.io/badge/godoc-reference-blue.svg)](http://godoc.org/github.com/miekg/pkcs11)
+
+This is a Go implementation of the PKCS#11 API. It wraps the library closely, but uses Go idiom
+were it makes sense. It has been tested with SoftHSM.
+
+## SoftHSM
+
+* Make it use a custom configuration file `export SOFTHSM_CONF=$PWD/softhsm.conf`
+
+* Then use `softhsm` to init it
+
+        softhsm --init-token --slot 0 --label test --pin 1234
+
+* Then use `libsofthsm.so` as the pkcs11 module:
+```go
+        p := pkcs11.New("/usr/lib/softhsm/libsofthsm.so")
+```
+## Examples
+
+A skeleton program would look somewhat like this (yes, pkcs#11 is verbose):
+```go
+    p := pkcs11.New("/usr/lib/softhsm/libsofthsm.so")
+    err := p.Initialize()
+    if err != nil {
+        panic(err)
+    }
+
+    defer p.Destroy()
+    defer p.Finalize()
+
+    slots, err := p.GetSlotList(true)
+    if err != nil {
+        panic(err)
+    }
+
+    session, err := p.OpenSession(slots[0], pkcs11.CKF_SERIAL_SESSION|pkcs11.CKF_RW_SESSION)
+    if err != nil {
+        panic(err)
+    }
+    defer p.CloseSession(session)
+
+    err = p.Login(session, pkcs11.CKU_USER, "1234")
+    if err != nil {
+        panic(err)
+    }
+    defer p.Logout(session)
+
+    p.DigestInit(session, []*pkcs11.Mechanism{pkcs11.NewMechanism(pkcs11.CKM_SHA_1, nil)})
+    hash, err := p.Digest(session, []byte("this is a string"))
+    if err != nil {
+        panic(err)
+    }
+
+    for _, d := range hash {
+            fmt.Printf("%x", d)
+    }
+    fmt.Println()
+```
+Further examples are included in the tests.

+To expose PKCS#11 keys using the
+[crypto.Signer interface](https://golang.org/pkg/crypto/#Signer),

+
+# TODO
+
+* Fix/double check endian stuff, see types.go NewAttribute()
+* Look at the memory copying in fast functions (sign, hash etc)
