-ek option

Allows you to specify the encryption key for strongly encrypted databases directly on the command line.

Syntax
dbmlsync -ek key ...
Remarks

If you have a strongly encrypted database, you must provide the encryption key to use the database or transaction log in any way, including offline transactions. For strongly encrypted databases, you must specify either -ek or -ep, but not both. The command fails if you do not specify a key for a strongly encrypted database.
