+# 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),
+please see [github.com/thalesignite/crypto11](https://github.com/thalesignite/crypto11).

+/* Before including this file (pkcs11.h) (or pkcs11t.h by
+ * itself), 5 platform-specific macros must be defined.  These
+ * macros are described below, and typical definitions for them
+ * are also given.  Be advised that these definitions can depend
+ * on both the platform and the compiler used (and possibly also
+ * on whether a Cryptoki library is linked statically or
+ * dynamically).
+ *
+ * In addition to defining these 5 macros, the packing convention
+ * for Cryptoki structures should be set.  The Cryptoki
+ * convention on packing is that structures should be 1-byte
+ * aligned.
+ *
+ * If you're using Microsoft Developer Studio 5.0 to produce
+ * Win32 stuff, this might be done by using the following
+ * preprocessor directive before including pkcs11.h or pkcs11t.h:
+ *
+ * #pragma pack(push, cryptoki, 1)
+ *
+ * and using the following preprocessor directive after including
+ * pkcs11.h or pkcs11t.h:
+ *
+ * #pragma pack(pop, cryptoki)
+ *
+ * If you're using an earlier version of Microsoft Developer
+ * Studio to produce Win16 stuff, this might be done by using
+ * the following preprocessor directive before including
+ * pkcs11.h or pkcs11t.h:
+ *
+ * #pragma pack(1)
+ *
+ * In a UNIX environment, you're on your own for this.  You might
+ * not need to do (or be able to do!) anything.
+ *
+ *
+ * Now for the macros:
+ *
+ *
+ * 1. CK_PTR: The indirection string for making a pointer to an
+ * object.  It can be used like this:
+ *
+ * typedef CK_BYTE CK_PTR CK_BYTE_PTR;
+ *
+ * If you're using Microsoft Developer Studio 5.0 to produce
+ * Win32 stuff, it might be defined by:
+ *
+ * #define CK_PTR *
+ *
+ * If you're using an earlier version of Microsoft Developer
+ * Studio to produce Win16 stuff, it might be defined by:
+ *
+ * #define CK_PTR far *
+ *
+ * In a typical UNIX environment, it might be defined by:
+ *
+ * #define CK_PTR *
+ *
+ *
+ * 2. CK_DECLARE_FUNCTION(returnType, name): A macro which makes
+ * an importable Cryptoki library function declaration out of a
+ * return type and a function name.  It should be used in the
+ * following fashion:
+ *
+ * extern CK_DECLARE_FUNCTION(CK_RV, C_Initialize)(
+ *   CK_VOID_PTR pReserved
+ * );
+ *
+ * If you're using Microsoft Developer Studio 5.0 to declare a
+ * function in a Win32 Cryptoki .dll, it might be defined by:
+ *
+ * #define CK_DECLARE_FUNCTION(returnType, name) \
+ *   returnType __declspec(dllimport) name
+ *
+ * If you're using an earlier version of Microsoft Developer
+ * Studio to declare a function in a Win16 Cryptoki .dll, it
+ * might be defined by:
+ *
+ * #define CK_DECLARE_FUNCTION(returnType, name) \
+ *   returnType __export _far _pascal name
+ *
+ * In a UNIX environment, it might be defined by:
+ *
+ * #define CK_DECLARE_FUNCTION(returnType, name) \
+ *   returnType name
+ *
+ *
+ * 3. CK_DECLARE_FUNCTION_POINTER(returnType, name): A macro
+ * which makes a Cryptoki API function pointer declaration or
+ * function pointer type declaration out of a return type and a
+ * function name.  It should be used in the following fashion:
+ *
+ * // Define funcPtr to be a pointer to a Cryptoki API function
+ * // taking arguments args and returning CK_RV.
+ * CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtr)(args);
+ *
+ * or
+ *
+ * // Define funcPtrType to be the type of a pointer to a
+ * // Cryptoki API function taking arguments args and returning
+ * // CK_RV, and then define funcPtr to be a variable of type
+ * // funcPtrType.
+ * typedef CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtrType)(args);
+ * funcPtrType funcPtr;
+ *
+ * If you're using Microsoft Developer Studio 5.0 to access
+ * functions in a Win32 Cryptoki .dll, in might be defined by:
+ *
+ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
+ *   returnType __declspec(dllimport) (* name)
+ *
+ * If you're using an earlier version of Microsoft Developer
+ * Studio to access functions in a Win16 Cryptoki .dll, it might
+ * be defined by:
+ *
+ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
+ *   returnType __export _far _pascal (* name)
+ *
+ * In a UNIX environment, it might be defined by:
+ *
+ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
+ *   returnType (* name)
+ *
+ *
+ * 4. CK_CALLBACK_FUNCTION(returnType, name): A macro which makes
+ * a function pointer type for an application callback out of
+ * a return type for the callback and a name for the callback.
+ * It should be used in the following fashion:
+ *
+ * CK_CALLBACK_FUNCTION(CK_RV, myCallback)(args);
+ *
+ * to declare a function pointer, myCallback, to a callback
+ * which takes arguments args and returns a CK_RV.  It can also
+ * be used like this:
+ *
+ * typedef CK_CALLBACK_FUNCTION(CK_RV, myCallbackType)(args);
+ * myCallbackType myCallback;
+ *
+ * If you're using Microsoft Developer Studio 5.0 to do Win32
+ * Cryptoki development, it might be defined by:
+ *
+ * #define CK_CALLBACK_FUNCTION(returnType, name) \
+ *   returnType (* name)

+ * If you're using an earlier version of Microsoft Developer
+ * Studio to do Win16 development, it might be defined by:
+ *
+ * #define CK_CALLBACK_FUNCTION(returnType, name) \
+ *   returnType _far _pascal (* name)
+ *
+ * In a UNIX environment, it might be defined by:
+ *
+ * #define CK_CALLBACK_FUNCTION(returnType, name) \
+ *   returnType (* name)
+ *
+ *
+ * 5. NULL_PTR: This macro is the value of a NULL pointer.
+ *

+ * this should best be defined by
+ *
+ * #ifndef NULL_PTR
+ * #define NULL_PTR 0

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# go-pkcs11uri
+
+Welcome to the go-pkcs11uri library. The implementation follows [RFC 7512](https://tools.ietf.org/html/rfc7512) and this [errata](https://www.rfc-editor.org/errata/rfc7512).
+
+# Exampe usage:
+
+The following example builds on this library [here](https://github.com/miekg/pkcs11) and are using softhsm2 on Fedora.
+
+## Example
+
+This example program extending the one found [here](https://github.com/miekg/pkcs11/blob/master/README.md#examples):
+
+```
+package main
+
+import (
+	"fmt"
+	"os"
+	"strconv"
+
+	"github.com/miekg/pkcs11"
+	pkcs11uri "github.com/stefanberger/go-pkcs11uri"
+)
+
+func main() {
+	if len(os.Args) < 2 {
+		panic("Missing pkcs11 URI argument")
+	}
+	uristr := os.Args[1]
+
+	uri, err := pkcs11uri.New()
+	if err != nil {
+		panic(err)
+	}
+	err = uri.Parse(uristr)
+	if err != nil {
+		panic(err)
+	}
+
+	module, err := uri.GetModule()
+	if err != nil {
+		panic(err)
+	}
+
+	slot, ok := uri.GetPathAttribute("slot-id", false)
+	if !ok {
+		panic("No slot-id in pkcs11 URI")
+	}
+	slotid, err := strconv.Atoi(slot)
+	if err != nil {
+		panic(err)
+	}
+
+	pin, err := uri.GetPIN()
+	if err != nil {
+		panic(err)
+	}
+
+	p := pkcs11.New(module)
+	err = p.Initialize()
+	if err != nil {
+		panic(err)
+	}
+
+	defer p.Destroy()
+	defer p.Finalize()
+
+	session, err := p.OpenSession(uint(slotid), pkcs11.CKF_SERIAL_SESSION|pkcs11.CKF_RW_SESSION)
+	if err != nil {
+		panic(err)
+	}
+	defer p.CloseSession(session)
+
+	err = p.Login(session, pkcs11.CKU_USER, pin)
+	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"))

+		panic(err)
+	}
+
+	for _, d := range hash {
+		fmt.Printf("%x", d)
+	}
+	fmt.Println()
+}
+```
+
+## Exampe Usage
+
+```
+$ sudo softhsm2-util --init-token --slot 1 --label test --pin 1234 --so-pin 1234
+The token has been initialized and is reassigned to slot 2053753261
+$ go build ./...
+$ sudo ./pkcs11-example 'pkcs11:slot-id=2053753261?module-path=/usr/lib64/pkcs11/libsofthsm2.so&pin-value=1234'
