kmip-go

A go implementation of the KMIP protocol and client, supporting KMIP v1.0 to v1.4. See KMIP v1.4 protocole specification

This library is developped for and tested against OVHcloud KMS.

NOTE: THIS PROJECT IS CURRENTLY UNDER DEVELOPMENT AND SUBJECT TO BREAKING CHANGES.

Usage

Add it to your project by running

go get github.com/ovh/kmip-go@latest

and import required packages

import (
	"github.com/ovh/kmip-go"
	"github.com/ovh/kmip-go/kmipclient"
	"github.com/ovh/kmip-go/payloads"
	"github.com/ovh/kmip-go/ttlv"
)

Then you can connect to your KMS service:

const (
	ADDR = "eu-west-rbx.okms.ovh.net:5696"
	CA   = "ca.pem"
	CERT = "cert.pem"
	KEY  = "key.pem"
)

client, err := kmipclient.Dial(
	ADDR,
	// Optional if server's CA is known by the system
	// kmipclient.WithRootCAFile(CA),
	kmipclient.WithClientCertFiles(CERT, KEY),
	kmipclient.WithMiddlewares(
		kmipclient.CorrelationValueMiddleware(uuid.NewString),
		kmipclient.DebugMiddleware(os.Stdout, ttlv.MarshalXML),
	),
	// kmipclient.EnforceVersion(kmip.V1_4),
)
if err != nil {
	panic(err)
}
defer client.Close()
fmt.Println("Connected using KMIP version", client.Version())

You can then use the high level client helper methods to create and send requests to the server:

resp := client.Create().
	AES(256, kmip.Encrypt|kmip.Decrypt).
	WithName("my-key").
	MustExec()
fmt.Println("Created AES key with ID", resp.UniqueIdentifier)

Or alternatively if more flexibility is required, craft your kmip requests payloads:

request := payloads.CreateRequestPayload{
	ObjectType: kmip.ObjectTypeSymmetricKey,
	TemplateAttribute: kmip.TemplateAttribute{
		Attribute: []kmip.Attribute{
			{
				AttributeName:  kmip.AttributeNameCryptographicAlgorithm,
				AttributeValue: kmip.AES,
			}, {
				AttributeName:  kmip.AttributeNameCryptographicLength,
				AttributeValue: int32(256),
			}, {
				AttributeName: kmip.AttributeNameName,
				AttributeValue: kmip.Name{
					NameType:  kmip.UninterpretedTextString,
					NameValue: "another-key",
				},
			}, {
				AttributeName:  kmip.AttributeNameCryptographicUsageMask,
				AttributeValue: kmip.Encrypt | kmip.Decrypt,
			},
		},
	},
}

response, err := client.Request(context.Background(), &request)
if err != nil {
	panic(err)
}
id := response.(*payloads.CreateResponsePayload).UniqueIdentifier
fmt.Println("Created an AES key with ID", id)

You can also send batches of requests:

batchResponse, err := client.Batch(context.Background(), &request, &request)
if err != nil {
	panic(err)
}
id1 := batchResponse[0].ResponsePayload.(*payloads.CreateResponsePayload).UniqueIdentifier
id2 := batchResponse[1].ResponsePayload.(*payloads.CreateResponsePayload).UniqueIdentifier
fmt.Println("Created 2 AES keys with IDs", id1, id2)

And directly craft your request message with one or more payloads batched together:

msg := kmip.NewRequestMessage(client.Version(), &request, &request)
rMsg, err := client.Roundtrip(context.Background(), &msg)
if err != nil {
	panic(err)
}
id1 := rMsg.BatchItem[0].ResponsePayload.(*payloads.CreateResponsePayload).UniqueIdentifier
id2 := rMsg.BatchItem[1].ResponsePayload.(*payloads.CreateResponsePayload).UniqueIdentifier
fmt.Println("Created a 5th and 6th AES keys with IDs", id1, id2)

}
