This document is intended as a specification of the protocol used for the communication between clients and servers to perform certain management operations on objects stored and maintained by a key management system. These objects are referred to as Managed Objects in this specification. They include symmetric and asymmetric cryptographic keys, digital certificates, and templates used to simplify the creation of objects and control their use. Managed Objects are managed with operations that include the ability to generate cryptographic keys, register objects with the key management system, obtain objects from the system, destroy objects from the system, and search for objects maintained by the system. Managed Objects also have associated attributes, which are named values stored by the key management system and are obtained from the system via operations. Certain attributes are added, modified, or deleted by operations.

The protocol specified in this document includes several certificate-related functions for which there are a number of existing protocols – namely Validate (e.g., SCVP or XKMS), Certify (e.g. CMP, CMC, SCEP) and Re-certify (e.g. CMP, CMC, SCEP). The protocol does not attempt to define a comprehensive certificate management protocol, such as would be needed for a certification authority. However, it does include functions that are needed to allow a key server to provide a proxy for certificate management functions.

In addition to the normative definitions for managed objects, operations and attributes, this specification also includes normative definitions for the following aspects of the protocol:

·         The expected behavior of the server and client as a result of operations,

·         Message contents and formats,

·         Message encoding (including enumerations), and

·         Error handling.

This specification is complemented by three other documents. The Usage Guide [KMIP-UG] provides illustrative information on using the protocol. The KMIP Profiles Specification [KMIP-Prof] provides a selected set of conformance profiles and authentication suites. The Test Specification [KMIP-UC] provides samples of protocol messages corresponding to a set of defined test cases.

This specification defines the KMIP protocol version major 1 and minor 0 (see 6.1).

1.1         Terminology

The key words "SHALL", "SHALL NOT", "REQUIRED", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. The words ‘must’, ‘can’, and ‘will’ are forbidden.

1  First steps

OpenSSL is a C library that implements the main cryptographic operations like symmetric encryption, public-key encryption, digital signature, hash functions and so on... OpenSSL also implements obviously the famous Secure Socket Layer (SSL) protocol. OpenSSL is avaible for a wide variety of platforms. The source code can be downloaded from www.openssl.org. A windows distribution can be found here. This tutorial shows some basics funcionalities of the OpenSSL command line tool. After the installation has been completed you should able to check for the version.

• ca To create certificate authorities.
• dgst To compute hash functions.
• enc To encrypt/decrypt using secret key algorithms. It is possible to generate using a password or directly a secret key stored in a file.
• genrsa This command permits to generate a pair of public/private key for the RSA algorithm.
• password Generation of “hashed passwords”.
• pkcs12 Tools to manage information according to the PKCS #12 standard.
• pkcs7 Tools to manage information according to the PKCS #7 standard.
• rand Generation of pseudo-random bit strings.
• rsa RSA data management.
• rsautl To encrypt/decrypt or sign/verify signature with RSA.
• verify Checkings for X509.
• x509 Data managing for X509.

2  Secret key encryption algorithms

OpenSSL implements numerous secret key algorithms. To see the complete list:

The list contains the algorithm base64 which is a way to code binary information with alphanumeric characters. It is not really a secret key algorithm as there is no secret key! Let’s see an example:

3  Public Key Cryptography

To illustrate how OpenSSL manages public key algorithms we are going to use the famous RSA algorithm. Other algorithms exist of course, but the principle remains the same.

3.1  Key generation

First we need to generate a pair of public/private key. In this example we create a pair of RSA key of 1024 bits.

So now it’s time to encrypt the private key:

3.2  Encryption

We are ready to perform encryption or produce digital signature.

• is the file to encrypt. This file must no be longer that 116 bytes =928 bits because RSA is a block cipher, and this command is low level command, i.e. it does not do the work of cutting your text in piece of 1024 bits (less indeed because a few bits are used for special purposes.)
• File that contains the public key. If this file contains only the public key (not both private and public), then the option must be used.
• the encrypted file.

To decrypt only replace by , and invert the input / output file as for decryption the input is the encrypted text, and the output the plain text.

3.3  Digital signatures

The next step is to be create a digital signature and to verify it. It is not very efficient to sign a big file using directly a public key algorithm. That is why first we compute the digest of the information to sign. Note that in practice things are a bit more complex. The security provided by this scheme (hashing and then signing directly using RSA) is not the same (is less in fact) than signing directly the whole document with the RSA algorithm. The scheme used in real application is called RSA-PSS which is efficient and proven to keep the best level of security.

• is the hash algorithm used to compute the digest. Among the available algorithm there are: SHA-1 (option which computes a 160 bits digests), MD5(option ) with 128 bits output length and RIPEMD160 (option ) with 160 bits output length.
• is the file that contains the result of the hash application on .
• file that contains the data to be hashed.

This command can be used to check the hash values of some archive files like the openssl source code for example. To compute the signature of the digest:

To check to validity of a given signature:

4  Public Key Infrastructure

4.1  What is a PKI? (in short)

4.1.1  The Problem: Man in the Middle Attack

One of the major breakthrough of public key cryptography is to solve the problem of key distribution. Secret key cryptography supposes the participants already agreed on a common secret. But how do they manage this in practice? Sending the key through an encrypted channel seems the more natural and practical solution but once again we need a common secret key to do this. With public key cryptography things are a lot simpler: if I want to send a message to Bob, I only need to find Bob’s public key (on his homepage, on a public key directory ...) encrypt the message using this key and send the result to Bob. Then Bob using his own private key can recover the plain text. However a big problem remains. What happens if a malicious person called The Ugly makes me believe that the public key he owns is in fact Bob’s one? Simply I will send an encrypted message using The Ugly’s public key thinking I’m communicating with Bob. The Ugly will receive the message, decrypt it, and will then encrypt the plaintext with Bob’s (real) public key. Bob will receive the encrypted message, will answer probably with another encrypted message using The Ugly’s public key (who once again managed to convince Bob, this public key belongs to me). Afterwards The Ugly will decrypt the message, reencrypt it with my public key, so I will really receive the Bob’s answer. Indeed I will be communicating with Bob, but without confidentiality. This attack is called “Man in the middle Attack”, where the man is of course The Ugly of our little story. So we need a mechanism to associate in a trustworthy way a public key to the identity of a person (name, identity card number ...). One of this mechanism is implemented in PGP. The idea is that every one builds his own net of trust, by having a list of trusted public keys, and by sharing these keys. The other solution is the use of a PKI.

4.1.2  A solution: Public Key Infrastructure

Public Key Infrastructure is a centralized solution to the problem of trust. The idea is to have a trusted entity (organization, corporation) that will do the job of certifying that a given public key belongs really to a given person. This person must be identified by his name, address and other useful information that may allow to know who this person is. Once this work his done, the PKI emits a public certificate for this person. This certificate contains between others:

• All the information needed to identify this person (name, birth date,...).
• The public key of this person.
• The date of creation of the certificate.
• The date of revocation of the certificate (a certificate is valid during 1 or 3 years in practice).
• The digital signature of all this previous information emitted by the PKI.

So now, if I want to send a private message to Bob, I can ask for his certificate. When I received the certificate, I must check the signature of the PKI who emitted it and for the date of revocation. If verifications pass then I can safely use the public key of the certificate to communicate with Bob. Indeed, in practice the way a PKI works is much more complicated. For example sometimes a certificate may be revocated before the date of end of validity has been reached. So a kind of list of revocated certificated has to be maintained and accessed every time you want to use a certificate. The problem of certificate revocation is really difficult in practice.

4.2  My first PKI with OpenSSL

This section will show how to create your own small PKI. Obviously this is only a tutorial and you SHOULD NOT base a real application only on the information contained in this page!

4.2.1  : let’s configure a few things

Before starting to create certificates it is necesarry to configure a few parameters. That can be done editing the file the is usually located in the directory of OpenSSL. This file looks like this:

4.2.2  PKI creation

First we must create a certificate for the PKI that will contain a pair of public / private key. The private key will be used to sign the certificates.

4.2.3  Creation of a user certificate

Now the PKI has got its own pair of keys and certificate, let’s suppose a user wants to get a certificate from the PKI. To do so he must create a certificate request, that will contain all the information needed for the certificate (name, country, ... and the public key of the user of course). This certificate request is sent to the PKI.
