ENCRYPT_MAC Configuration Parameter

default value

medium

range of values

One or more of the following options, separated by commas:

• off does not use MAC generation.
• low uses XOR folding on all messages.
• medium uses SHA1 MAC generation for all messages greater than 20 bytes long and XOR folding on smaller messages.
• high uses SHA1 MAC generation on all messages.

For example: ENCRYPT_MAC medium,high

takes effect

when Enterprise Replication is initialized

The ENCRYPT_MAC configuration parameter controls the level of message authentication code (MAC) generation.

The level is prioritized to the highest value. For example, if one node has a level of high and medium enabled and the other node has only low enabled, then the connection attempt fails. Use the off entry between servers only when a secure network connection is guaranteed.
