Usage

Properties

• Length: The length of the string (Bytes). Default is 128 which is the equivalent of a 256 character string.
• _NoEcho: _NoEcho is a CustomResource feature that Lulo implements. Use this if you are generating strings that are sensitive, such as keys or passwords, to ensure that they do no leak. Simple set _NoEcho to true.

Since the only property that can be changed is the length the secret will be regenerated for any update.
