Dear Customer,
This letter contains a brief description of DSNlink NE Version 3.0 for OpenVMStm. It also lists the DSNlink files and explains what to do after you copy the kit to your system.
These are the topics in this letter:

1 About DSNlink NE Version 3.0 for OpenVMS
DSNlink NE Version 3.0 for OpenVMS (where "NE" means no encryption), is a special kit for customers who cannot install DSNlink Version 3.0, which encrypts all communications. Although DSNlink NE Version 3.0 does not encrypt communications or contain encryption software, it does have all other new features and bug fixes that are in DSNlink Version 3.0.
Customers who want DSNlink Version 3.0, which encrypts communications, can order a copy on CD-ROM. Contact your local Compaq office to place the order. The part number for DSNlink Version 3.0 (with encryption) is as follows:
QA-6FRAA-H8 --- DSNlink Version 3.0 for OpenVMS
1.1 Improved Authentication
When either your system or the Compaq host initiates a connection, the
systems first perform authentication. The goal of the process is for
the customer and host systems to verify their identities to each other
before establishing a communication connection. The systems must
successfully authenticate themselves before messages are exchanged.
Authentication has been enhanced with the addition of stronger, hash-based message authentication code (HMAC) functions. During the authentication process, DSNlink Version 3.0 combines a message with your authentication key and processes the result with industry-standard secure hash functions to generate a hash-based message authentication code (HMAC) for the digital signature. The HMAC algorithm follows RFC 2104 guidelines.
The HMAC authentication methods in DSNlink Version 3.0 are:
The older MD5 authentication method, which produces a 128-bit signature, was used in earlier versions of DSNlink. Your DSNlink Version 3.0 system will use this method if the host system is running an earlier version of DSNlink. This method does not follow RFC 2104 guidelines and is not as secure as the HMAC methods mentioned above.
1.2 New Authentication Key
Previously, DSNlink used only MD5 to authenticate all connections.
Both your system and the Compaq host had identical MD5 keys.
In DSNlink NE Version 3.0, a key that is compatible with the HMAC functions is required for authentication. It is a single key for the SHA1, RMD160, and SR160 authentication methods. It has this location and file name format:
DSN$KEYS:HMAC-DIGITAL-access_number
If you install DSNlink NE Version 3.0, on a system with an earlier version of DSNlink, the installation renames the existing MD5-DIGITAL-access_number keys to HMAC-DIGITAL-access_number. The contents of the MD5 key are not changed, just the file name.
If you install DSNlink NE Version 3.0, on a system without an earlier version of DSNlink, the installation prompts you for the authentication key. You can use the DSNlink authentication key from another of your DSNlink systems. If you have no previous versions of DSNlink, Compaq provides an authentication key for you to enter at the installation prompt for a key.
If new or existing customers request an authentication key, the HMAC key they receive is 16 characters longer than the MD5 keys. Customers are encouraged to request the key because it is harder for an adversary to break. For more information, contact Compaq.

3 Documentation File Names and Descriptions
Table 2 lists the documentation files for DSNlink Version 3.0 that are in the docs directory for the OpenVMS kits. Note that text and PostScript documentation files are included in the DSNLINKNE030.S_DCX_AXPEXE and DSNLINKNE030.S_DCX_VAXEXE save sets. Therefore, you do not have to copy the documentation files from the docs directory unless you want the HTML and/or PDF files that appear only in this :CD-ROM kit.

The decompressor needs to know the filename to use for the
decompressed file. If you don't specify any, it will use the
original name of the file before it was compressed, and
create it in the current directory. If you specify a
directory name, the file will be created in that directory.
