====== Encryption of sensitive data ======

You can set up encryption of sensitive data in the configurator so that they are AES encrypted. The AES key can be created or selected during configuration (see [[en:ueberblick:installation:konfiguration:start|]] at **Setting the encryption**). The key should saved be on the server and can only be read by eBissService. You **should backup the key file**, in case all encrypted data is lost and cannot be restored.  Note: You can activate crypting on existing systems but you must check and safe the passwords in the communication channels after activation of the crypting.

Note: It is possible to activate the encryption for systems that have already been created, but this can lead to passwords from existing communication channels having to be re-entered. Also, existing passwords are not encrypted until they are saved, which is why the communication channel has to be saved. 

====== Encrypted values ======

Following values encrypted:
   * The db connection string in the config files (eBiss.Service.exe.config, eBiss.Service.exe32.config, etc.).
   * Variable values of variables configured in the variable definition
   * The passwords of following communication channels: FtpSendChannel, FtpReceiveChannel, FtpServerSendChannel, FtpServerReceiveChannel, Pop3ReceiveChannel, sFtpReceiveChannel, sFtpSendChannel, SmtpSendChannel, WebDavSendChannel, WebDavReceiveChannel.


The icon shows, if the value is encrypted (number lock) or just hidden (normal lock) (s. [[en:ueberblick:installation:konfiguration:crypt|]]).
====== Encrypted values in job-steps ======

To use encrypted values in the job-step **BackendObjectRetrieverEx** using the variables of the standard system partner.You can also use encrypted values in the Job-Step BackendObjectRetrieverEx using the variables of the standard system partner. To do this, encrypt the variable of the default system partner and reference it using the prefix "$" in the variables of the **BackendObjectRetrieverEx**   

For example, the value for the **eBiss.DbAdapter.ConnectionString1**.  ConnectionString refers to the encrypted variable value **eBiss.DbAdapter. ConnectionString1** of the default system partner in the following screen:
