1.1	45
10.1	46	{{formcycle/}} provides the option to enable encryption for the database to prevent against unauthorized access. Meta data is always encrypted and form data may be encrypted optionally.

	52	; Encrypt form data
	53	: Enable this option to encrypt data of submitted forms including all attachments. When you use a mySQL database, [[form specific data tables>>Formcycle.UserInterface.MyForms.Inbox]] are encrypted as well.
	54	; Update encryption of data sets
	55	: When thic option is checked, the data gets encrypted with the entered password.
	56	; Password confirmation
	57	: The password used to encrypt the data with the selected algorithm.
	58
1.1	59	{{warning}}
10.1	60	Depening on the chosen encryption algorithm, the password and the Java version you are using it may become necessary to install the //Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files//. If these files are missing, an appropriate error message will be displayed.
1.1	61	{{/warning}}
	62
10.1	63	== Migrating data sets ==
1.1	64
10.1	65	Enable the option //Update encryption of data sets// to migrate existing, encrypted data. The encrypted data is decrypted with the password entered in //Password confirmation// and encrypted again with the new password.
1.1	66
10.1	67	== Create or update the database ==
1.1	68
10.1	69	Click on //Save and update// to continue to update the database and system. If the database is empty, new tables will be created. Otherwise, the database is updated. Once the database is up-to-date, all necessary system updates are run automatically.
