URL Change to v2.2.1 Certificate Management Library (CML)



All -- With the recent update to the DigitalNet web site, the source code for the Certificate Management Library (CML) has been relocated to

http://digitalnet.com/knowledge/cml_home.htm

Alternatively, you can reach the home page for all of the Secure Message Protocol (SMP) freeware libraries from the DigitalNet home page (www.digitalnet.com) by first clicking on "Knowledge Bank" in the upper-right corner, and then on "SMP".  This will lead you to all of the freeware libraries supported by DigitalNet.

Thank you.

Subject: v2.2 Certificate Management Library (CML) Now Available
Date: Mon, 24 Feb 2003 18:14:02 -0500
From: "Pawling, John" <John.Pawling@xxxxxxxxxxxxxx>
To: <imc-cml@xxxxxxx>
All,

DigitalNet (formerly Getronics Government Solutions) has delivered
the Version 2.2 Certificate Management Library (CML) for Microsoft
Windows, Sun Solaris and Linux.  The v2.2 CML and documentation is 
freely available at:
<http://www.digitalnet.com/hot/cml_home.htm>.  

Applications requiring Public Key Infrastructure (PKI) security 
services can use the CML to meet their X.509 certificate and 
Certificate Revocation List (CRL) processing requirements.  
The v2.2 CML is described in the v2.2 CML Application Programming
Interface (API) document.  It implements the 2000 X.509 Recommendation
certification path verification processing rules and SDN.706 profile.
It meets the majority of the IETF PKIX RFC 3280 Certificate/CRL Profile
requirements.  There are some unsupported features such as 
Delta CRLs.  The v2.2 CML Abstract Syntax Notation One (ASN.1)
decodes X.509 Certificates and CRLs.  It requires the v1.5
Enhanced SNACC ASN.1 software that is freely available from:
<http://www.digitalnet.com/hot/snacc_home.htm>.

The CML provides robust certification path building capabilities such
as using cross certificates.  The CML uses the accompanying Storage 
and Retrieval Library (SRL) (optionally) to provide local certificate
and CRL storage management functions.  The SRL (optionally) provides 
remote directory retrieval capabilities using the Lightweight
Directory Access Protocol (LDAP).

The CML has been thoroughly tested including validating X.509 
Certificates and CRLs created by a variety of Certification 
Authority (CA) products, and signed using the Digital Signature
Algorithm (DSA) and RSA algorithms.  Further enhancements, 
ports and testing of the CML are still in process.  Further
releases of the CML will be provided as significant 
capabilities are added. 


v2.2 CML includes the following enhancements (compared to v2.1 
CML release):

1) Significantly improved robustness of the certification path
building capabilities (especially the building of paths in
cross-certified PKI environments).  

2) Significantly improved performance and reduced memory 
requirements of CRL decoding and processing. 

3) Enhanced the CML C++ library to support name constraints
processing of the IPAddress GeneralName type.

4) Enhanced CML ASN.1 code to process both correct X.501 
Clearance attribute syntax.

5) See the CML web site and CML API document for further details.


v2.2 SRL includes the following enhancements (compared to v2.1 
SRL release):

1) Enhanced SRL to remove the dependency on a local LDAP 
distribution located in the SMPDist directory.  The new SRL uses
the distribution that the customer is using on their platform. 

2) Enhanced SRL to remove the dependency on LDAP header files.  

All source code for the CML is being provided at no cost and with no
financial limitations regarding its use and distribution. Organizations 
can use the CML without paying any royalties or licensing fees.  The
CML was originally developed by the U.S. Government.  DigitalNet is 
enhancing and supporting the CML under contract to the U.S. Government.
The U.S. Government is furnishing the CML software at no cost to the
vendor subject to the conditions of the CML Public License provided
with the CML software.  

The CML makes calls to an algorithm-independent CTIL API that provides
access to a variety of external crypto libraries.  There is a CTIL for 
each crypto library that maps the generic CTIL API calls to the 
specific calls for that crypto library.  DigitalNet provides CTILs for
the Microsoft CAPI v2.0, Crypto++, RSA BSAFE, Spyrus SPEX/ and 
FORTEZZA Cryptologic Interface libraries.  DigitalNet also provides a 
PKCS #11 CTIL that enables PKCS #11-compliant libraries to be used 
with the CML.  The underlying, external crypto libraries are not 
distributed as part of the CML software. 


The CML has been successfully tested with the v2.2 S/MIME Freeware 
Library (SFL) that is freely available from 
<http://www.DigitalNet.com/hot/sfl_home.htm>.  

The CML has been successfully tested with the v2.2 Access Control 
Library (ACL) that is freely available to everyone from: 
<http://www.DigitalNet.com/hot/acl_home.htm>.

The CML has been successfully used to build and verify 
certificate paths used in the Bridge Certification Authority (BCA)
demonstration which includes cross-certified hierarchical and non-
hierarchical PKIs.  The BCA Interoperability Test Suite (BITS)
is a free and openly available test resource provided to 
facilitate vendor development of secure, interoperable Public
Key Enabled applications.  The CML has been used to successfully
develop and verify the BITS X.509 certification paths available
from <http://bcatest.atl.DigitalNet.com>.  

The National Institute of Standards and Technology (NIST) is 
providing a standard test suite of X.509 certificate paths
<http://csrc.nist.gov/pki/testing/x509paths.html> that can be
used for testing applications against RFC 2459.  The CML was 
used to successfully process the NIST test data.

The CML meets the requirements stated in the SDN.706 Certificate/
CRL Profile required by the U.S. Defense Message System (DMS) 
project.

The Internet Mail Consortium (IMC) has established a CML web page
<http://www.imc.org/imc-cml> and a CML mail list which is used to: 
distribute information regarding CML releases; discuss CML-related 
issues; and allow CML users to provide feedback, comments, bug 
reports, etc.  Subscription information for the imc-cml mailing list 
is at the IMC web site listed above.  

All comments regarding the CML source code and documents are welcome. 
This CML release announcement was sent to several mail lists, but
please send all messages regarding the CML to the imc-cml mail list
ONLY. Please do not send messages regarding the CML to any of the IETF
mail lists.  We will respond to all messages sent to the imc-cml mail 
list.
