Encryption key used to encrypt sensitive data stored in configuration files.
Level: Deploy Target Options
The Application Encryption Key is used to encrypt and decrypt sensitive data of the database connection strings and URL parameters.
Its length has to be 32 characters (Hexa is expected) and it's typically a GUID. By default, it's the GUID of the Knowledge Base.
In Java, the key is stored in a file named application.key, in the folder where the client.cfg is located. Its content is as follows: 7E2E22D26FF2989E2444852A85E57866
The first line contains the key related to database connection information and parameter encryption used when the Encrypt URL Parameters property is set to Session key.
The second line contains the key related to URL Parameter encryption used when the Encrypt URL Parameters property is set to Site key.
In .NET, the Application Deployment Tool creates a KeyResolver.dll with those keys (To encrypt the URL with a different key, follow the steps of SAC 29874).
In both .NET and Java, the Application Deployment Tool creates the files and encrypts the database connection information before packaging the application.
