Set Up Encrypted Communication Between Aleph GUI and Server

Description

Is there step-by-step documentation on how to set up encrypted communication between Aleph GUI and server?

Resolution

1. Aleph server:
In $alephe_tab/tab_version, add line:

! 1 2 3 4 5 6
!!!!!!-!!!!!-!-!-!!!!!!!!-!!!!!!!!!!
21.01E ALEPH Y 2 12345678

2. Restart PC server

3. GUI: add file to GUI tree:
C:\AL500\alephcom\TAB\DES_KEY.DAT

File contains key from column 5 of $alephe_tab/tab_version above

4. Change in alephcom.ini:
[Main]
Encryption=2
Version=21.01E

5. restart GUI

Additional Information

Notes: The encryption is for both ways: Client->Server and Server->Client. This function was introduced in June 2001 in Aleph 15 with rep_ver #003300.

The following encryptions can be used:

See col. 4 Encryption of $alephe_tab/tab_version 
0 - none
1 - ALEPH
2 - DES
3 - Kerberos
4 - LDAP (Authentication only);
5 - Aleph Encryption and LDAP Authentication;
